So thats the solution to latency. They should have software on computers that detect bluetooth or aptx latency and tells the computer to sync the video or music you're playing to 200ms slower for bluetooth or in aptx case by 30-100 ms. I dont know why there's no such thing already. It could easily be a driver or software and someone could make money selling it.
Just want to say that I'm high and I noticed no latency issues in the vid, but liked and subscribed because I had a fun time listening to a grown man explaining about Bluetooth and heating a stick. Great video.
There is a very common bug with lots of Bluetooth devices (especially ones that use the Apple chipset from like 6 years ago). If you simply pause the video for 60 seconds, then click play (do not disconnect or turn anything off) it should resync itself for the rest of the session.
Wrong on live audio and video. Light travels much faster than sound. There is absolutely latency, your brain just can't perceive it at short distances. Ever seen a baseball get hit from afar? Latency like a mofo.
I used the examples you used in the video to adjust the MS difference on my speakers for the bluetooth to make everything in sync, 33ms was ideal. Thank you!
It is great video. You are a talented teacher. Everything is very clear and with good jokes. I watched your video with wired headphones. The effect of lagging sound is also clear on the built-in speaker in the gadget. Thank You. 👍
Great thank you. Just a point. When knocking those pieces of bonking wood - it wood (or is that would) be better if you didn't do it in a repetitive manner as we cant associate which clonk belongs to which bonk. So bonk - wait one second - bonk - wait a different length of time - bonk - wait yet another different time - -- you get my drift.
@@unknownuser8454 you need the sound the second you hit a string. worrying about this for movie snobs is just childs play. we are doing actual work an it requires precision. we arent hoping to see dora the explora or santa clause spew vomit out her mouth at the same time her mouth opens an no earlier or later. im here because i have unoticable lag in videos but when i hit a guitar string it sounds right after an is near impossible to play synced to a band an just pisses me off.. oh and to answer the original statement. you wont see lag you can still feel when hitting a guitar string. 15ms sounds like we are borderlining unplayable cause double that is bad. watchign this video has nothing on watching this video if you were hitting that piece of wood an it taking time to sound out after. he himself would probably be out of time with the tap tap tap if the lag wasnt later added in post production
For me, as I use bluetooth headphones, it already has a latency but I cannot know (yet) how to measure that. So, I thought it would be very nice for those who want to check the latency to do kind of "reversed latency" (that is, "earlency") so we can see directly by listening on our BT ear or headphones that the sound and the image is synchronised so we would be able to say e.g. "I have a 33 ms of latency". Thanks.
I'm actually watching this over Miracast which has considerable video latency but listening through headphones connected to the phone so audio is ahead of video. And that 300ms audio latency part was only one normal for me 😂
A video for sync testing purposes should be filmed at 60 fps at least. This one is 23.976 fps (~42 ms per frame) so it lacks clarity. Thank you anyway. )
When you strike that thing to produce the sound, the time gap between two successive strikes should be kept far more than the worst case audio latency. In other words, the time gap should be atleast 1 second. This will help the viewers to judge better. Otherwise, it may happen that the first strike appears to be mute, and the second strike's sound comes nearby the visual frame of the third strike, and so on. I hope you get my point.
Didn't think that Dolby digital can add so much latency! It was prominent on my fire stick connected to sony blue ray through bluetooth & video through a home projector.
Nice demo! I'd have preferred more light for the recording so there would be less motion blur. In addition, for the 0 ms latency you kept the stick touching the instrument after the hit which makes it easier to notice the correct timing. For the final test you hit quite hard and the stick bounced so much that it's impossible to see the the exact hit time in the video due motion blur. Dropping a metal ball on hard surface would make even a better test target for the audio/video sync.
thanks for the examples... I am about to buy a digital audio matrix mixer that has 3ms latency but I was planing to monitor my microphone into headphones and I was wondering how hearing my own voice will sound with 3ms delay in my headphone...
Its funny because with my headphones with their own delay the last test was perfectly synchronized. Except I didnt hear the first tick and had one extra at the end of video.
Oh man it's one hit behind with my Bluetooth headphones with your 0ms Ldac codec changing some settings made it sync again.... Confusing because the settings don't show a change....
It's interesting...the 200ms was the only section I noticed any sort of syncing issues. To give passerbys some context, I'm wearing the 2019 Samsung Galaxy Buds, which normally have syncing issues when you put one of the titular Buds back into your ear.
Interesting... Got my new in-ears today and even without activating their low latency "game mode" I was not even able to notice any delay at all before the demonstration. As if they were 0ms latency. Impossible, I know. But this makes me believe that either something was wrong with the video or, well, I made a great purchase for the small budget that I had. Thanks, I guess 🙂
Ya right sound can be measure for signal system work 😀👍🏿👍🏻 But context same distance and weather. Different sound/signal in same weather example Northern & Russia same extremely Snow but different object frequency
Honestly watching this on my desktop with headphones I can't really tell too much of a difference. However when using my bluetooth headphones with youtube, before it syncs itself, I notice it being significantly worse than even the 300ms here, especially if using any other app other than youtube that doesn't sync itself.
But the Picture also has a Latency. When I look for a Monitor Review I really care for the Input Lag of the device. It is not easy to measure absolute but at least comparable. Non-Gaming-Monitors can have up to 60 ms of Input lag, 20-40 ms is what you can expect on a 60 Hz Office-Monitor (less Delay on the top of the picture, more on the bottom). So if you have a quick wireless connection it can be easily perfectly sync with the picture.
I was so out of sync that the very last clave (idk if that’s how it’s spelled) sounded like it was in sync, only for me to realize that there was an extra beat.
it kind of defeats the purpose of complaining about it though if you have to slow it down to a quarter speed to detect it. I personally couldn't see/hear any difference at all. What I could SEE was that towards the end it didn't look like the wood was connecting at all, my brain will chalk that up to frame rate issues and not audio issues, I couldn't even tell the latency when he was talking. People on the internet almost talked me out of getting a set of bluetooth headphones for casual gaming, after seeing this video I can tell that I have no issue with this kind of input lag at all.
Interestingly enough i never lost sync it always seemed to match but i was try to focus so hard on what i seen and heard that my brain probably had the ability to match them without effort

ha, it was but with that extra phantom "clack" at the end.
Latency:
0 milliseconds: Live audio & video.
33 milliseconds: Audio happens faster.
100 milliseconds: Audio happens normally.
200 milliseconds: Audio happens slower.
300 milliseconds: Audio seems to be out of sync.

In the whole YT universe there is a single video raising the issue of BT latency. The video is this one.❤
How tf did you play 0ms latency on my delayed wireless earphones??!?
I guess it could be the compensation of OS between youtube video and audio.
Very well explained. Thanks for sharing 👍.
This video shows me NOT to buy a $460 audio delay unit with a maximum of 135 ms. Our A/V latency is in the 300 ms range. Thank yoou Brent!

I came to the comments to say this same thing. Due to my current delay this exact thing occurred
The last one was in sync for me, only that the first tap was mute and the last tap sound came from nowhere.
"Should be hopelessly out of sync by now" XD why did this make me laugh so much?

The low frame rate is evident that the frames where the claves are striking each other are missing.
