Hi Gerald... I used this fix to correct an issue I had with a 54 music show. Ran a 3-camera shoot thru a studio grade video switcher/mixer, that also got a messy two track ( in sync). I also recorded the session on a 12-track audio recorder. I found that my mixed down multi track ( and raw) ended up just shy of 2 sec short over that 54 min. So problem solved... but wtf is happening to make them not sync. I am recording the audio at 16bit/48Hz, which is the same standard the video system uses... so where is the timing difference coming in. One of the other people in this org was in broadcast for decades,, symphony recording etc... said he had never seen this issue in his entire career.... thanks for your introspection
Yeah, sure, that works. But how about if you DO edit your video in time to audio by cutting, moving around etc, MAKE it in time, export it. Then when you upload to youtube it's out of sync on SOME devices and not all? I uploaded unlisted the other day and everything seems fine on my devices, but I checked a friends phone and the video-audio was out of sync..
Couple Notes: Right click your timeline timecode/playhead area, Show Audio Time units - then you can align same as in Audition, and probably just use the Rate Stretch tool (R key?) to conform as needed, too. Save the Audition export steps. Right clicking your audio and video in the bins and hitting "Merge Clips" and then based on waveforms, append tracks, delete original audio -- with claps and no drift has never not worked for me. If you're getting audio drift just recording in Audition with nothing intensive going on on your PC, I definitely recommend digging into your frequency settings or something, that's really not normal at all other than when your CPU is under intense load causing your audio driver to stall out.
I really don't think that "Audio Time Units" works as well as Audition. It's still clunky and sticks to frames. Audition is buttery. The Rate Stretch Tool is a good stopgap, but it's definitely clumsier than the stretching in Audition. Audition allows more decimal places too. Merge Clips is effective with shorter clips, but it uses the standard sync method and that doesn't change rates for fixing drift. The reason why this happens has little to do with load in my case (because it happens on external recorders as well) and everything to do with relying on frame markers instead of using a properly synced time code. It's always out of sync by about .001%, which is the same as the difference between 30 and 29.97 or 24 and 23.976, etc. And in Premiere you can't choose the correct percentage of correction down to the exact decimal place like you can in Audition. I think everyone suffers from the drift if not using time codes, but it's possible they don't notice because we're only talking about a frame of drift every 10 minutes or so. Once you get into 1-2 hour recordings though, it becomes pretty noticeable in my opinion, but it's still only about 1/2 second out, and might go undetected.
Edit: Audio Time Units + Rate Stretch Tool is a lot better than using neither of those things in Premiere. I don't mean to discount your tip completely. It is a significantly smoother vs not using it. I still like Audition better though. The tools and layout have audio in mind, so I find it faster. But good tip.
Well, that did the trick for me. My camera doesn't have an internal mic, I know right, so I had to sync the drift on two claps one in front and one in the end. Since I couldn't match the internal audio to the external audio I needed the video as a reference to properly sync the audio. Sorry, All I meant to say is, thanks for this tip ;)
You can do this all in premiere. First, sync up your clips in the timeline the best you can, then right click anywhere in the time section of the timeline and choose "Show Audio Time Units" this will allow you to zoom in way closer and even see individual sine curves of the audio. From here you can further sync it as accurately as Adobe audition. Next I would cut the start of both clips where the claps start Then scroll to the end and cut the end of the audio on both clips at a known audio break. (If you have audio drift they should be different lengths) Then right click your video track and choose speed/duration. Copy the length of the video in minutes:frames and cancel out Choose your Audio clip that is trimmed, right click, select "speed/duration" and paste the length timecode that you copied from the video. Be sure to click maintain pitch checkbox as well. You should now have synced audio. Alternatively you can go to your toolbar at the top, click and hold the ripple edit tool and select "rate stretch" from the drop down. You can now stretch the audio clip to accurately sync to the video. Please note, you should take your timeline out of "Show Audio Time Units" after you are complete, otherwise cutting, zooming, and scrolling through your timeline will be much harder
This is a concisely written guide for Premiere. Thank for doing this. I use the rate stretch tool version of this, because I'm used to it and fast at it, but I'll give the speed/duration method a try to mix it up next video. And yeah, always re-disable audio time units or cutting is a mess. They often won't even line up.
You can achieve sub-frame positioning of audio in Premiere by right-clicking on the timecode ruler above the timeline and selecting "Show Audio Time Units." This allows for precise adjustments at a finer level within the timeline. Additionally, you have the option to simply stretch the audio directly within Premiere without the necessity of utilizing Adobe Audition for such tasks.
So it's actually, actually those youtubers' fault when A/V go out of sync, I've been thinking for a while to upgrade my GPU just because of this. Thank you Gerald.

Then you can adjust audio by individual samples instead of by frame. This way you can line up your claps perfectly between camera audio and external sound.
You can actually stretch the audio clip aswell in Premiere directly. Just use the clip speed tool. Works for audio aswell and you can stretch the track. I dont remember the correct name since I am using Davinci now.
Speed / Duration is okay, but the problem is you can't get it to the exact % you want, because it rounds and doesn't provide enough accuracy or decimal places. There is the Rate Stretch tool, which is decent, but again, doesn't line up as well because it's subject to frame positions.
Ok thanks for the info. I used it on clips around 10 min and it worked pretty well. Didn't use it on longer clips though. For Resolve I am doing it via Audition as you show in this video. Works very good.
Hey Gerald, actually in premiere you don't have to be subject to just frame positions with audio. Just select your audio then in the preview window, hit the wrench and checkmark "show audio time units". Now you have the freedom at the waveform level to stretch or slide. After I do that, I really zoom in a lot then hold the alt-key + the right or left cursor to slide it. You might have to hold it down for awhile and let the auto repeat of the keyboard setting do the work to actually move it enough. Now you have all the precision you need :)
@@geraldundone If you hit the timeline hamburger menu and enable "Show Audio Time Units", you can adjust audio in finer increments than just frames! Edit: whoops someone already said it 😬
Hey! If you want no restrictions with the time with video frames, you have to click the 3 lines next to the sequence you are in, and choose "Show Audio Time Units", and you will have like in Audition all the audio to synch perfectly!
You know when you watch a video and the person explains exactly what’s going wrong with your project and how to solve it?! That just happened, thank you so much 🤙
Thanks so much for this video! I've been agonising for months over whether my issues were in Traktor, my camera, or something I was doing wrong. Now syncing my dj mixes with video perfectly. I've adapted your technique to use with Resolve and Audacity. Just takes a little more work to stretch the audio. 👍👏
Exact same thing can be done inside premiere pro. Use alt+arrow keys to move layer precisely. And there is time stretch tool in premiere too. But great video 👍👍👍
Funny, I've never had this happen before. I've recorded 5-7 minute long segments with my GH5, using the Tascam DR-60D mk II recorder for external sound. I use a slate for syncing and the sound has always worked fine. But, if it ever does, I have this wonderful video to fix it. Thanks, Gerald.
Yeah, you won't notice it much at 5-7 minutes. When I say "long recordings" I mean like an hour or two. You'll drift by about .001%, so that will only be a portion of a frame at 5 minutes. Not noticeable. Thanks for the kind words and sharing your experience! Cheers. 😃👍
Thank you for posting this. Long gone are the days when I meticulously chopped up clips, hoping the mouth and audio sync didn't come out looking like an overdubbed 70's Kung Fu film.
That's very useful, cheers.. By the way, synching in Premiere gets more accurate if you go the little dropdown at the top right of the sequence window and select "show audio time units". You will then be able to drag the audio by much smaller increments without it snapping to the next frame. Switching it back afterward is better for editing your video.
WOW, this video addressed the exact situation I was facing down. My videographer gave me 4 video clips at 48000 Hz sample rate plus 3 audio clips at 44100 Hz (from a Lavalier mic) and the audio drift was noticeable, especially on the longer clips. I followed your video exactly and it worked perfectly (except for the time I forgot to mute the scratch track in Audition). You da man! I will use this in future situations. Thank you!
There is an even easier way, and it's 10x faster than this... you simply take the 44.1kHz and you load them on an audio editing software, and then you export those as 48kHz. They will be sample-accurate...
Great vid man. I've only ever had this happen once before and it was because audio was recorded in 44,1khz vs 48khz. Ever since then I started recording all audio in 48khz. Not sure why it really matters because I edit a lot of music videos that have music at 44,1khz and it always syncs perfectly.
This may or may not be a f'ing lifesaver, my man. No joke, this is like actual job saving- if it solves the problem I'm currently having, that is. I'll get back to you in a bit.
Long time since anyone commented on this. I use a Zoom H6, plug in my microphones to it, then use the line out to plug into my camera, or into the back of the ATEM Mini pro. I also record the session on the Zoom and can use that as my audio source. Syncs well and is easy to fix if need be.
I record my audio on a Olympus LS14 and I've never had any problem with it going out of sync with my Nikon or Fujifilm cameras. However, I tend to record in multiple short clips (10 to 15 minutes) at a time. Incidently, the LS14 is a great audio recorder!
*Audio syncing:* You can move the audio wherever you want as there are no frames, if Premiere won't let you do this then its because its amateur software. *Audio drift:* This occurs because your camera and audio recorder are running at different sample rates or you have PreManure set to import all wavs as 44.1khz! I've never had this issue in the last 1/4 century except on other people's audio as they where camera people and had no sound recordist.
Dude, your videos are incredible, and your "what is happening?" intro always cracks me up. This explanation of sync drift is concise but also incredibly intuitive. I've worked with Audition and music production and DJ software quite a bit so I'm used to these concepts, but your explanation of why you need to keep the original scratch audio track conveyed a difficult concept in a very small number of words. Always look forward to your videos! Now please do a comparison of HLG vs F-Log on the Fuji XT-3 and tell me which one to use and how to expose for it using the NINJA V, when I have a dynamic light source in the background :)
Recommend to use the show audio time units option when moving audio in Premiere. Also Pluraleyes plugin is a huge timesaver for syncing and drift correcting audio. 😀
I have a 30 minute 4K sync with external audio and I’m using Plural Eyes 4. There is still audio drift because the clip is so long and plural eyes is not recognizing the audio drift so using Adobe Premier helps when Plural Eyes 4 cant fix it properly.
@@Gutie5g, on little trick is to adjust the speed of the separate audio track by using rate stretch tool to match the waveform at the beginning and end. Often that will fix a slight drift that Pluraleyes doesn't catch. Good luck friend!
The radio station I work at today still swears by Cool Edit Pro as their audio software of choice. I didn't realize Audition came from Cool Edit Pro until recently, and that was when I realized how out of date the software they use at most radio station's is.
So damn helpful. I'm so glad to finally know WHY my ZOOM tracks were always drifting from my GoPro tracks, even if I synched them perfectly at the start of my 20-minute clips.
Holy shit I have had this problem so much that for the longest time I used to cry when I looked at the imported audio and see drifts of up to several seconds sometimes. I used to use laptops running Audacity or Audition attached through a USB soundcard to my mics. I recently bought a Zoom H1n to see if I could avoid this problem, but I haven't had the chance to test it yet. Thank you for your video, I didn't know that Audition had those little bars and I was using Premier to sync them up. Apparently the desync is due to OS schedulers, where they assign a CPU priority to processes and this causes delays when switching back to the process that's recording audio from the input. Even if you have nothing else running in the background, the overhead from the OS's own processes (such as Windows Update or the NetSvc) can cause a delay in recording that adds up. It's written to the buffer correctly but the file write gets delayed. So a dedicated recorder ostensibly doesn't have to deal with this.
Thanks for the info! I'd love to know if you notice a difference between recording through the computer vs the Zoom when it comes to drift. Your explanation intrigues me. Cheers! 😃👍
@@geraldundone is there a way to contact you an not end up in your spam box? 😅 I probably have time this new year's eve, so I was about to record a test shot outside. I'll make a video and post it on my channel, and if it's easy for you I'll reply right here with the link. Maybe you can make a follow up video as to why this happens.
For a quick and dirty way (and similar results) you can also do all this within premiere. You cut the clean and scratch tracks to the same points, then use speed/duration to match the length of the clean track to the scratch track and sync them up. Your way is actually easier, I just hate switching apps :) Great vid!
Thanks! 😃 That definitely works, but not perfectly on really long recordings because Premiere is actually missing a decimal place that Audition has. Premiere rounds the 3rd place off, where Audition doesn't. So I'm willing to switch apps to get that slight better accuracy. But for me, I'm not even switching apps because I do my audio in Audition anyway. Good tip though. If it works for your clips than it's a time saver for sure.
But it would be especially on long recordings 😃 Just to clarify: I'm referring to adjusting the duration not speed of the clean track. So if you take a video recording of 01;44;37;27 (a recent project), and your clean track is 01;44;45;15, I paste the first value in the clean track's duration, assuming identical cut points, being a frame off at that duration is negligible. I do agree, for the best accuracy you have to leave premiere. Fine, I'll switch apps! 😃
Nice technique - not sure it would work for music videos though, right? Because you can't (or shouldn't, at least) time-stretch your audio master of the song?
Been using this method for years, funny how it now got recommended for me Nowadays the easiest way to record camera and audio, is straight to OBS but I have to use this method whenever dealing with external recorders.. It seems like because traditional cameras record at either 23.976 or 59.94, somewhere down the line, the camera will either skip or freeze frames but maintain audio length so it slows down the audio
Thanks for your work, I have a teeny weeny gaming channel, but have recently decided to use it to really learn about editing (I don't have a camera), I've swapped from Camtasia to Vegas Pro and Davinci Resolve but even though you're an Adobe guy, your stuff is really helpful and inspiring so keep it coming
Hey Gerald, Is there any explanation for why this happens? I find this happens often with professionally recorded audio done in ProTools and am worried that modifying the speed of the clip in audition might alter the pitch of the music. I am currently editing 20 minute live sessions and the audio end up being faster by about 5/6 frames by the end. Is it actually down to how to audio is processed and exported?
I do this with only premiere: Turn on audio time units, place the good audio track, align the start, then use the rate stretch tool on the audio. No Audition and rendering needed.
This is definitely the best way to do it within Premiere. I made the tutorial with Audition because I use Audition for my audio anyway, but if you were trying to keep it quick and just in Premiere, or didn't want to do certain audio corrections in Audition, this would be the way to go.
@@geraldundone Not to mention that Audition has wicked scopes and additional filters for sweetening the audio as long as you're in the program. At least half of your videos in 2018 have directly benefited me and my processes. Keep up the great work!
Haha! Perfect intro. Love your channel. I learn so much about things I didn't even know I should know. Thank you for such quality videos. Happy new year and best wishes for 2019!
You can amend your timeline display to show audio rather than video frames. This can help with the syncing part then just use a rate stretch tool within premiere.
Thanks for the suggestion. Unfortunately it still suffers from that jumpy-frame-sticking thing where it doesn't let you slide it smoothly to line up perfectly. I find only audio programs let you do that. Also, I record my audio in Audition and correct it in there too, because it's more useful for normalizing and noise suppression. But the rate stretch tool is useful in Premiere if you need to do it all in one place quickly as you mentioned. I just wish you could line the sync up as nicely.
Thank you, I had a terrible time trying to resolve this yesterday, I will give it a go edit: I tried this and it actually worked! So happy I found a solution that worked. Thank you so much!!!
But you can either merge or sync audio directly in Premiere Pro Gerald. For instance, just drag marquee around you two tracks then right click and choose synchronise.
That won't work for audio drift because the rate isn't the same. All it does is sync it (usually poorly) in one spot, but it still drifts by the end of the clip.
Thank you for this episode. I use Audacity, and I don't know if it has the same tools at Audition, but you got me on the right track. Right now, I am doing the cutting up the audio track into pieces to sync. Not fun.
very interesting learning about sub frame editing, which I didn't know about. But wouldn't we still be constricted by Premiere's Speed/Duration settings in terms of fixing audio drifts?
Movies Are Dope Yes, I’m just talking about getting things lined up. From time to time for a really long tracks I’ve done something as simple as just cut the audio track and just sync up the different sections so everything is mostly synced
Solid video! Helped a ton... So GoPro breaks up videos clips. I've been nesting them to make them one clip can you take a nested clip into Audition. seems like I can not. Suggestions?
Thank you from the bottom of my heart 💚💚💚💚 You made me find what i was looking for in 7 years of lost Thanks dear very thanks i even download your video and put it in my best videos folder in my phone to save it Thank you dear again god bless you
I would love for ever if you show us what rig you used to record this audio and how you edited this audio. I saved this video, shared with many people as the best audio quality video I ever seen. Could you share how can we make our audio quality sound at least close to yours ? Thanks
YES ! Am familiar with the Synchronize feature on Adobe locking up multi camera tracks through the, 'Mixdown' setting however am now trying to Synchronize a new 4 Cam Multi Camera Shoot to a Master Audio Track recorded previously but after I draw over the 4 independent tracks then right click on the group my Synchronize tab is GHOSTED! Can you offer me a Solution?
Used to syncing stuff as a sound producer and worked with Audition for a long time. Now with videos I do the same *right within Vegas Pro 12* : no frames restriction (can be turned off for audio edits) and stretching is present (including various modes for speech, musical instruments, pitch correction/preservation etc.). No need for external software. And it all inside a simple 5-year old programm. I was thinking of switching to Premiere after purchasing a new powerful laptop, but can't it do such easy things still? I would think twice then.
Hey, Paul. You can do it in Premiere. It's called the Rate Stretch Tool. I just find it is a little clumsier than Audition. And I run my audio through Audition anyway, so I figured I might as well sync it while I'm in there too since it's easier.
FCPX is easier in this problem. You just time stretch the audio track within the timeline to match the video audio. Much quicker. I have this problem with all my recordings and do it manually every time. Trying to figure out how to resolve it from my recorder once and for all.
Helpful tip for aligning audio in Premiere, if you hit the hamburger menu beside the Sequence name/tab, and select "Show Audio Time Units" in the second section, you can now drag freely and makes the snap-to-frame becomes...undone. ;) Probably already knew that by now since this was last year. Helpful tip and once you align, trim the edges to the clip length and re-link it to the video, you can turn it back off and continue working! Doesn't apply to sync drift, but just syncing in general!
on the time line ruler scale you can right click and choose audio measurement instead. This method help your timeline to be just like in Au. because if you going to strech there is also tools in PR No need to export to Au to waste your ram
I really don't think that "Audio Time Units" works as well as Audition. It's still clunky and sticks a bit. Audition is buttery. But is definitely an improvement and a good tip! 😃 The Rate Stretch Tool is a good stopgap, but it's definitely clumsier than the stretching in Audition. Audition allows more decimal places too.
I know this is an old video but in Adobe Premier Pro CC 2017 and in the context of recording gameplay content with Shadowplay my gameplay audio track drifts out of sync with the actual gameplay visual track. There is no 2 audio tracks I can compare to as one is visual. In that case I right-click my tracks and unlink them, then I right-click the gameplay audio track only and select "Speed/Duration". For me setting that to 99.85% does the trick when recording the source with Shadowplay. The exact % is trial and error off course.
I have to say, the only time my audio goes out of sync nowadays is when I record it with a portable Philips voice tracer dictation device, while my video with a Lumix camera. When I use a smartphone or a DAW on a PC, there is no sync loss in usual length videos. But I know how bad it can go with dissynced equipment, especially when a camera is working in PAL while audio device is synced to NTSC (stupid legacy standards)
Great solution, Gerald. I was wondering why this happens in the first place if my in-camera audio and my external audio are both at the same sample rate. Can internal clocks really be that different?
Thanks for watching! I hope you all have a happy new year. 😃🙏

Hey! If you want no restrictions with the time with video frames, you have to click the 3 lines next to the sequence you are in, and choose "Show Audio Time Units", and you will have like in Audition all the audio to synch perfectly!
You know when you watch a video and the person explains exactly what’s going wrong with your project and how to solve it?! That just happened, thank you so much 🤙
This is why I love youtube. Just fixed my audio drift with your help. Thanks man!
Awesome! Glad to hear it. Thanks for saying so.
Thanks so much for this video! I've been agonising for months over whether my issues were in Traktor, my camera, or something I was doing wrong. Now syncing my dj mixes with video perfectly. I've adapted your technique to use with Resolve and Audacity. Just takes a little more work to stretch the audio. 👍👏
Exact same thing can be done inside premiere pro.
Use alt+arrow keys to move layer precisely.
And there is time stretch tool in premiere too.
But great video 👍👍👍
Funny, I've never had this happen before. I've recorded 5-7 minute long segments with my GH5, using the Tascam DR-60D mk II recorder for external sound. I use a slate for syncing and the sound has always worked fine. But, if it ever does, I have this wonderful video to fix it. Thanks, Gerald.
Yeah, you won't notice it much at 5-7 minutes. When I say "long recordings" I mean like an hour or two. You'll drift by about .001%, so that will only be a portion of a frame at 5 minutes. Not noticeable.
Thanks for the kind words and sharing your experience! Cheers. 😃👍
Thanks!
Thank you for posting this. Long gone are the days when I meticulously chopped up clips, hoping the mouth and audio sync didn't come out looking like an overdubbed 70's Kung Fu film.
Dude you just saved my life. Holy smokes. I've been searching for ages for a solution to this. THANK YOU.
Awesome! Glad to hear it. Thanks, Troy!
That's very useful, cheers.. By the way, synching in Premiere gets more accurate if you go the little dropdown at the top right of the sequence window and select "show audio time units". You will then be able to drag the audio by much smaller increments without it snapping to the next frame. Switching it back afterward is better for editing your video.
Audition also has "Automatic Speech Alignment" tool. Designed pretty much exactly for this problem. ;)
Where is this tool??? :)
This saved me 6 hours of audio recording. Thank you so much!
This saved my project form failing, i almost lost my hope that i can fix this issue somehow, thanks a lot
You saved me about 3 hours of editing. Got it done in like 10 seconds. I love you!
I was literally like 😱😲🤭when you stretched it! THANK YOU SO MUCH! I have done WAY to much manual un-drift-ifying!
WOW, this video addressed the exact situation I was facing down. My videographer gave me 4 video clips at 48000 Hz sample rate plus 3 audio clips at 44100 Hz (from a Lavalier mic) and the audio drift was noticeable, especially on the longer clips. I followed your video exactly and it worked perfectly (except for the time I forgot to mute the scratch track in Audition). You da man! I will use this in future situations. Thank you!
There is an even easier way, and it's 10x faster than this... you simply take the 44.1kHz and you load them on an audio editing software, and then you export those as 48kHz. They will be sample-accurate...
Great vid man. I've only ever had this happen once before and it was because audio was recorded in 44,1khz vs 48khz. Ever since then I started recording all audio in 48khz. Not sure why it really matters because I edit a lot of music videos that have music at 44,1khz and it always syncs perfectly.
Thanks! Yeah, that one is pretty common from what I've read. I also keep everything in 48kHz for that reason too.
thank you man.I was looking for a solution to exactly this problem. Thanks to you I won't be dealing with 1 millisecond audio drifts
This may or may not be a f'ing lifesaver, my man. No joke, this is like actual job saving- if it solves the problem I'm currently having, that is. I'll get back to you in a bit.
thank you so much! this tutorial helped us fix an audio sync bug we had been working at for an hour in premiere - life-saver!!
Long time since anyone commented on this. I use a Zoom H6, plug in my microphones to it, then use the line out to plug into my camera, or into the back of the ATEM Mini pro. I also record the session on the Zoom and can use that as my audio source. Syncs well and is easy to fix if need be.
YOU SAVED MY JOB AND PROBABLY IM GONNA GET RAISED. THANK YOU KIND SIR I LOVE YOU
My pleasure! Thanks for letting me know.
I record my audio on a Olympus LS14 and I've never had any problem with it going out of sync with my Nikon or Fujifilm cameras. However, I tend to record in multiple short clips (10 to 15 minutes) at a time. Incidently, the LS14 is a great audio recorder!
*Audio syncing:* You can move the audio wherever you want as there are no frames, if Premiere won't let you do this then its because its amateur software.
*Audio drift:* This occurs because your camera and audio recorder are running at different sample rates or you have PreManure set to import all wavs as 44.1khz!
I've never had this issue in the last 1/4 century except on other people's audio as they where camera people and had no sound recordist.
Thanks for the great tips on the audio sync. This reminds me I need to get back in the studio to undo some music.
why does this happen in the first place¿? Oh, and if you change your ruler unit you can move audio by samples and not frames, so its more precise
Dude, your videos are incredible, and your "what is happening?" intro always cracks me up. This explanation of sync drift is concise but also incredibly intuitive. I've worked with Audition and music production and DJ software quite a bit so I'm used to these concepts, but your explanation of why you need to keep the original scratch audio track conveyed a difficult concept in a very small number of words. Always look forward to your videos! Now please do a comparison of HLG vs F-Log on the Fuji XT-3 and tell me which one to use and how to expose for it using the NINJA V, when I have a dynamic light source in the background :)
Thanks! I'm really glad to hear that. Really appreciate this comment. And thanks for the suggestion too. Cheers! 😃🙏
Recommend to use the show audio time units option when moving audio in Premiere. Also Pluraleyes plugin is a huge timesaver for syncing and drift correcting audio. 😀
I have a 30 minute 4K sync with external audio and I’m using Plural Eyes 4. There is still audio drift because the clip is so long and plural eyes is not recognizing the audio drift so using Adobe Premier helps when Plural Eyes 4 cant fix it properly.
@@Gutie5g, on little trick is to adjust the speed of the separate audio track by using rate stretch tool to match the waveform at the beginning and end. Often that will fix a slight drift that Pluraleyes doesn't catch. Good luck friend!
Yes, love Audition. I grew up using it with a community radio station back when it was "Cool Edit Pro", then purchased my own Audition v1.5 lol
The radio station I work at today still swears by Cool Edit Pro as their audio software of choice. I didn't realize Audition came from Cool Edit Pro until recently, and that was when I realized how out of date the software they use at most radio station's is.
Happy New Year to you and all the Undones.
Thanks, John! You too. 😃🙏
Thank you! I was pulling my hair out trying to fix this issue. You saved what's left of my sanity.
I need help.. i don’t know what i’m doing wrong. i’m doing this same thing i keep getting audio drift.
Once again....you make the best vids
Thanks, Steve!
Bro THANK YOU!!! You have NO IDEA how much time you just saved me!!! This is amazing.
Life saver for my long recordings-thank you so much!
So damn helpful. I'm so glad to finally know WHY my ZOOM tracks were always drifting from my GoPro tracks, even if I synched them perfectly at the start of my 20-minute clips.
Holy shit I have had this problem so much that for the longest time I used to cry when I looked at the imported audio and see drifts of up to several seconds sometimes. I used to use laptops running Audacity or Audition attached through a USB soundcard to my mics. I recently bought a Zoom H1n to see if I could avoid this problem, but I haven't had the chance to test it yet. Thank you for your video, I didn't know that Audition had those little bars and I was using Premier to sync them up.
Apparently the desync is due to OS schedulers, where they assign a CPU priority to processes and this causes delays when switching back to the process that's recording audio from the input. Even if you have nothing else running in the background, the overhead from the OS's own processes (such as Windows Update or the NetSvc) can cause a delay in recording that adds up. It's written to the buffer correctly but the file write gets delayed. So a dedicated recorder ostensibly doesn't have to deal with this.
Thanks for the info! I'd love to know if you notice a difference between recording through the computer vs the Zoom when it comes to drift. Your explanation intrigues me. Cheers! 😃👍
@@geraldundone is there a way to contact you an not end up in your spam box? 😅 I probably have time this new year's eve, so I was about to record a test shot outside. I'll make a video and post it on my channel, and if it's easy for you I'll reply right here with the link. Maybe you can make a follow up video as to why this happens.
I marked you as an approved commenter, so you should be good!
@@geraldundone thank you, that makes me feel all warm and fuzzy inside :)
This video is very helpful, unfortunately I always forget how to do this so I've rewatched it probably 100 times now
Bro imma try this when im back home , this thing was making me crazy over this week
Dude This Helped Me Fr Thank You So Much I was Getting Hella Frustrated 😁
For a quick and dirty way (and similar results) you can also do all this within premiere. You cut the clean and scratch tracks to the same points, then use speed/duration to match the length of the clean track to the scratch track and sync them up. Your way is actually easier, I just hate switching apps :)
Great vid!
Thanks! 😃 That definitely works, but not perfectly on really long recordings because Premiere is actually missing a decimal place that Audition has. Premiere rounds the 3rd place off, where Audition doesn't. So I'm willing to switch apps to get that slight better accuracy. But for me, I'm not even switching apps because I do my audio in Audition anyway. Good tip though. If it works for your clips than it's a time saver for sure.
But it would be especially on long recordings 😃 Just to clarify: I'm referring to adjusting the duration not speed of the clean track. So if you take a video recording of 01;44;37;27 (a recent project), and your clean track is 01;44;45;15, I paste the first value in the clean track's duration, assuming identical cut points, being a frame off at that duration is negligible. I do agree, for the best accuracy you have to leave premiere. Fine, I'll switch apps! 😃
Ah, I see. Yeah, that's better than speed %. 😃
Nice technique - not sure it would work for music videos though, right? Because you can't (or shouldn't, at least) time-stretch your audio master of the song?
Great tutorial and very helpful as per usual👍
Thanks for this video!! This is what my life has been missing! My videos are usually long and the drift gets crazy! I can't wait to try this out!
Audition is awesome. If you're making videos, you need Audition as much as Premiere.
This is great! You can change the mode so you can move audio less than one frame though for future reference. Thanks for the fix!
2021 year... it's wasn't fixed... You is my master! Thanks!
Been using this method for years, funny how it now got recommended for me
Nowadays the easiest way to record camera and audio, is straight to OBS but I have to use this method whenever dealing with external recorders..
It seems like because traditional cameras record at either 23.976 or 59.94, somewhere down the line, the camera will either skip or freeze frames but maintain audio length so it slows down the audio
This video SAVED me! Can't Thank you enough for making this. Huge help! Subscribed and supporting from here on out!
Thanks for your work, I have a teeny weeny gaming channel, but have recently decided to use it to really learn about editing (I don't have a camera), I've swapped from Camtasia to Vegas Pro and Davinci Resolve but even though you're an Adobe guy, your stuff is really helpful and inspiring so keep it coming
Hey Gerald, Is there any explanation for why this happens? I find this happens often with professionally recorded audio done in ProTools and am worried that modifying the speed of the clip in audition might alter the pitch of the music. I am currently editing 20 minute live sessions and the audio end up being faster by about 5/6 frames by the end. Is it actually down to how to audio is processed and exported?
I do this with only premiere: Turn on audio time units, place the good audio track, align the start, then use the rate stretch tool on the audio. No Audition and rendering needed.
This is definitely the best way to do it within Premiere. I made the tutorial with Audition because I use Audition for my audio anyway, but if you were trying to keep it quick and just in Premiere, or didn't want to do certain audio corrections in Audition, this would be the way to go.
@@geraldundone Not to mention that Audition has wicked scopes and additional filters for sweetening the audio as long as you're in the program.
At least half of your videos in 2018 have directly benefited me and my processes. Keep up the great work!
Gerald, your presentation is excellent! Thank you!
Great advice! I knew it couldn't be entirely my drumming that was making longer songs so far off from the original track, lol :)
Haha! Perfect intro. Love your channel. I learn so much about things I didn't even know I should know. Thank you for such quality videos. Happy new year and best wishes for 2019!
Thank you very much! Happy new year to you too! 😃👍
Why does sync drift happen in the first place? Is there a way to prevent it altogether, rather than relying on fixing it in post?
Yes, record all source in 48kHz
Whew I've never seen a single hair straying out that far parallel to the ground! HD that is ) Thanks man!
Awesome information that I wouldn't have thought of! Great video sir!
I am going to try this later but i think you will save me a LOT of time with this.
useful video thanks! I'm just starting my video journey and knew nothing about audition despite having access to it :D
You can amend your timeline display to show audio rather than video frames. This can help with the syncing part then just use a rate stretch tool within premiere.
Thanks for the suggestion. Unfortunately it still suffers from that jumpy-frame-sticking thing where it doesn't let you slide it smoothly to line up perfectly. I find only audio programs let you do that. Also, I record my audio in Audition and correct it in there too, because it's more useful for normalizing and noise suppression. But the rate stretch tool is useful in Premiere if you need to do it all in one place quickly as you mentioned. I just wish you could line the sync up as nicely.
Gerald Undone yeah, I like your way better it seems the best way having it in audition for editing purposes too. Keep up the good work!
Thank you, I had a terrible time trying to resolve this yesterday, I will give it a go
edit: I tried this and it actually worked! So happy I found a solution that worked. Thank you so much!!!
But you can either merge or sync audio directly in Premiere Pro Gerald. For instance, just drag marquee around you two tracks then right click and choose synchronise.
That won't work for audio drift because the rate isn't the same. All it does is sync it (usually poorly) in one spot, but it still drifts by the end of the clip.
Thank you! This is a burning issue, now I finally know what to do. Happy new year! 😀
Thank you for this episode. I use Audacity, and I don't know if it has the same tools at Audition, but you got me on the right track. Right now, I am doing the cutting up the audio track into pieces to sync. Not fun.
This is an awesome tip!! I can't wait to use this on my next project! Happy New Year!
Thank you so much for this. This is EXACTLY what I needed.
Don't forget about "Sub frame Editing" to perfectly sync audio
very interesting learning about sub frame editing, which I didn't know about. But wouldn't we still be constricted by Premiere's Speed/Duration settings in terms of fixing audio drifts?
Movies Are Dope Yes, I’m just talking about getting things lined up. From time to time for a really long tracks I’ve done something as simple as just cut the audio track and just sync up the different sections so everything is mostly synced
Casey McBeath gotcha. Ok, thanks for clearing up my confusion
Solid video! Helped a ton... So GoPro breaks up videos clips. I've been nesting them to make them one clip can you take a nested clip into Audition. seems like I can not. Suggestions?
Thank you from the bottom of my heart 💚💚💚💚
You made me find what i was looking for in 7 years of lost
Thanks dear very thanks i even download your video and put it in my best videos folder in my phone to save it
Thank you dear again god bless you
You saved hours of my life! THANKS!!! 🤩🤩🙏🏼🤩🤩
Thank you Gerald for sharing this trick, it works!
Final Cut Pro X users can use it’s built in audio sync tool a few clicks and your done. It will even do waveform analyses for you.
I would love for ever if you show us what rig you used to record this audio and how you edited this audio. I saved this video, shared with many people as the best audio quality video I ever seen. Could you share how can we make our audio quality sound at least close to yours ? Thanks
YES ! Am familiar with the Synchronize feature on Adobe locking up multi camera tracks through the, 'Mixdown' setting however am now trying to Synchronize a new 4 Cam Multi Camera Shoot to a Master Audio Track recorded previously but after I draw over the 4 independent tracks then right click on the group my Synchronize tab is GHOSTED!
Can you offer me a Solution?
Thanks for all your videos in 2018. Have a happy new.
You too! 😃🙏
Man this video literally saved one of my podcast recordings. Bruh thanks for sharing ✌🏾
Used to syncing stuff as a sound producer and worked with Audition for a long time. Now with videos I do the same *right within Vegas Pro 12* : no frames restriction (can be turned off for audio edits) and stretching is present (including various modes for speech, musical instruments, pitch correction/preservation etc.). No need for external software. And it all inside a simple 5-year old programm. I was thinking of switching to Premiere after purchasing a new powerful laptop, but can't it do such easy things still? I would think twice then.
Hey, Paul. You can do it in Premiere. It's called the Rate Stretch Tool. I just find it is a little clumsier than Audition. And I run my audio through Audition anyway, so I figured I might as well sync it while I'm in there too since it's easier.
FCPX is easier in this problem. You just time stretch the audio track within the timeline to match the video audio. Much quicker. I have this problem with all my recordings and do it manually every time. Trying to figure out how to resolve it from my recorder once and for all.
wow thank you!! it solved my drifting audio issues Subbed! Keep creating great contents!
Helpful tip for aligning audio in Premiere, if you hit the hamburger menu beside the Sequence name/tab, and select "Show Audio Time Units" in the second section, you can now drag freely and makes the snap-to-frame becomes...undone. ;) Probably already knew that by now since this was last year. Helpful tip and once you align, trim the edges to the clip length and re-link it to the video, you can turn it back off and continue working! Doesn't apply to sync drift, but just syncing in general!
on the time line ruler scale
you can right click and choose audio measurement instead.
This method help your timeline to be just like in Au.
because if you going to strech there is also tools in PR
No need to export to Au to waste your ram
I really don't think that "Audio Time Units" works as well as Audition. It's still clunky and sticks a bit. Audition is buttery. But is definitely an improvement and a good tip! 😃
The Rate Stretch Tool is a good stopgap, but it's definitely clumsier than the stretching in Audition. Audition allows more decimal places too.
I know this is an old video but in Adobe Premier Pro CC 2017 and in the context of recording gameplay content with Shadowplay my gameplay audio track drifts out of sync with the actual gameplay visual track. There is no 2 audio tracks I can compare to as one is visual. In that case I right-click my tracks and unlink them, then I right-click the gameplay audio track only and select "Speed/Duration". For me setting that to 99.85% does the trick when recording the source with Shadowplay. The exact % is trial and error off course.
I have to say, the only time my audio goes out of sync nowadays is when I record it with a portable Philips voice tracer dictation device, while my video with a Lumix camera. When I use a smartphone or a DAW on a PC, there is no sync loss in usual length videos.
But I know how bad it can go with dissynced equipment, especially when a camera is working in PAL while audio device is synced to NTSC (stupid legacy standards)
Great solution, Gerald. I was wondering why this happens in the first place if my in-camera audio and my external audio are both at the same sample rate. Can internal clocks really be that different?
