Just cleaned-up 400+Gb of cache clips, this is insane. Thank you very much Patrick!
Same bro, I just thought DaVinci cleaned up the cache everytime I closed the program. Boy was I wrong 🤣🤣
350 gigs of my 1T drive...
I regularly have well over 1TB of render cache.
@@anameyoucantremember HOW TO CLEAN IT WHERE IT IS LOCATED ??
Me too. Huge thanks Patrick!!!
You stop it…
FIRST! ❤
I'm a new dr user and fell victim to this setting. I was banging my head trying to figure out what was going on. Very few videos out there explaining this in the way that you have. It's an essential step to getting adequate playback performance. Thank you so much for providing the tip!
dude, I'm happy for you hahaa. Back when I didn't know I'd wonder why the heck my SSD would have so little space. Well I was using some heavy effects on uncompressed 10-bit! holy shmokes. Now I always go in a delete fusion cache after each vid render.
This was me aswell, soo frustrating until I found this video
Davinci Resolve suddenly stopped rendering my projects 5 days ago. After watching other UA-cam videos, I suspected it was because my special effects and add-ons froze the program. Other videos advised to render the videos in place and make sure the "red lines turned into blue" before proceeding with the render. I did not see that on my end and could not figure out how to set that up - until I watched this video and learned I have to select "Playback >> Render Cache >> Smart" ... and now I FINALLY see what I'm supposed to see! And after it all rendered in place, it finally worked! Something so minor, but I'm still learning this software! Thank you for this! ☺👏
This is an especially important setting to be aware of. We have an internal 2 TB SSD (Samsung) dedicated to caching only, and it would fill up very quickly when we edited one-hour documentaries. A hard disk that is set for the cache and has reached its capacity (meaning it is full) will result in many playback issues with the dreaded red no-media clip warnings. So, indeed, regularly monitor how much space you have left for caching, as DR will not warn you of a full disk. Thanks for sharing the video.
Very useful bro!!... just cleaned 200gb thanx ur tip!!... Gracias from Chile !! 🙌
You are Absolutely Right! The average, Hell even the advanced Professional UA-camr doesn't need Uncompressed 10-bit files.. But try not to use a high level compression CODEC for these. That will slow down your editing performance. there's a reason you want light or no compression... Thanks for the Heads Up!
Such a cute mothatrucka! Love your very unique earlobes, and love to listen to you talk and explain. You have a very genuine and helpful/ nice and humorfull attitude it seems like.
(Judging from watching only this video)
Don't change nothin about that. Luv, and and subbed. Thank you for helping mate!
I literally have a 500GB NVMe SSD in my system dedicated to Resolve render cache, and I kept running out because I guess it's set to uncompressed. Thanks for this video, as it reminded me to try changing the cache format setting.
Sure am glad we have you to show us how to rein in this wild and crazy program with all its hidden pitfalls! "With great powers come great settings, er, responsibility:" uncle Ben Parker. 😄😄 Patrick, thanks for this alert!
Yup the last one was insane! I had more than 300 gb occupied by DaVinci for my UA-cam videos 😂 insane! I even turned off cache media
Thank you very much.Decode thing works for me because i use clips taken from iphone :)
You can also create proxies (lower quality clips used just for editing), there's great tuturials out there on that
DUUUUDEEE You just saved my life! Thank you so much
My Cache Folder is about 150gb, i never checked it until now. Is it Okay to delete it all permanently? Im afraid to loste presets, settings or smartbins - but they aren't effected by the cache files, right?
yup, you won't lose any of that! those are stored in your databases.
@@PatrickStirling Thanks
I missed it till I reminded the video to 4:07
I forgot where the files were stored lol
Thank you! Thank you! Thank you!
me, sitting here all along calculating how much a new computer will cost
and here you come with a solution for my jitter and stutter timeline issues!
Incredible! 🤘🤘🤘
I just need this video , love you Patrick :D
I didn't even know what these options actually did in Davinci Resolve!
This video just improved my experience using this program by 10 fold.
Patrick, thanks a million. I'm a new subscriber and I've been making UA-cam videos since 2018. This was a great video. I'm going to clear a bunch of space. Thank you for the heads up and thank you for this video and all of your videos. Top notch content right here!
So you changed my life with this video... thanks
Thank you! I knew about cleaning the cache, but not the change in settings. Tried rendering something yesterday (14 min 50fps UHD) with a LOT of your effect thingies and it stopped calculating the time at 25 hours 😂
I had this problem after the first completely new project this year (without starting from a preset), it was set to 10 bit uncompressed and playback of render cache was slower and more jerky than without render cache. It took me a few days until i found this setting. I first thought the whole rendering was somehow bugged in the new version until i found out about this setting in some forum.
I don't understand why this is on 10 bit uncompressed by default. Not even my (pretty high end) system could handle that (in 4K).
These are all hidden stuffs for starters - thank you for sharing
Just remember that DNxHR LB to HQ are only 8-bits. HQX is 12-bits. Use LB only if you have to, like on a laptop with small SSD.
This needs to be pinned!
So you say, use DNxHR SQ or HQX?
"DNxHR LB to HQ" what you mean with "to".
Would be cool if you can clarify, I'm non-foreign (english).
@@DerHouy 8-bit 4:2:2 is used in LB, SQ and HQ. 12-bit 4:2:2 is used in HQX. 12-bit 4:4:4 is used in DNxHR 444. Compression rates LB 22:1, SQ 7:1, HQ 4.5:1, HQX 5.5:1, 444 4.5:1. Do not use LB unless you have to. SQ and HQ are both the same heavy for CPU. HQX is more CPU heavy. You can also use GoPro Cineform which is even more CPU hungry, but has constant quality, not constant bitrate.
Why is it important to work with 12-bits when cacheing? When you are working/updating the Colorgrade the Cache shouldn’t be used anymore until you go back to editing and create another cache right? and for Editing Playback the 8 bit should be enough. I would be interested to get your opinion on that. cheers mate
@@mariuswickli3206 Correct - you can use 8-bit cache for editing. For color grading it may be risky. Every node in a chain can be cached, so to prevent clipping more bits should be used. Also if you have source video that is 10-bit, you need at least 10-bit cache, but consider 12-bit to prevent clipping in node chain. And in Resolve you do not have separate caches for editing and color grading and if you need cache for editing, you may need cache for color grading, too.
O. M. G.
I was getting corrupted edits because of this. 298GB of garbage cache clips. Thank you for this!!
I am hiting my head, with what to do with fusion render cache for days end, the render employs %100 of HDD read/write, and as result I get lagging when press playback. That "Render cache format" on DDNxHR SQ solved it wow😮 . Also I would mention that I had to set Timeline Proxy Resolution to Full*, otherwise it wouldn't make a difference ❤. Amazing amazing amazing - this bottleneck is so silly 😢 thank you for the education.
I'm guessing, like CacheClip location, this has to be set for every individual project. Again. Davinci Resolve does have special ways of doing things...
Great tips as always, thanks! I’d love to see a tutorial on setting up DR on a new computer. Is there a way to transfer all you plugins / settings / powergrades etc without manually recreating them all? That’d be amazing!
This is hilarious, my first video I did a relatively simple video edit that tanked my pc at the beginning of the video so I would just skip over it until it came time to export otherwise it would freeze
I can't thank you enough, this is a life saver
So you have to make sure your effects are all blue or they wont render out?
799GB in ONE CacheClip directory. I had no idea.
It might just be a habit from my Premiere days, but I really really really miss being able to manually render specific sections of my timeline without have to render out a different playback file. It's so archaic and feels a lot like editing back before Adobe had dynamic link switching between After Effects and Premiere just to essentially preview files.
you can. Right mouse click - It's called 'render in place' super easy mate. DVR for the win.
@@LandyVlad_Rides But that exports a standalone file that then replaces the edited clip. It doesn't simply render a preview file.
@@ChunkyJo oh i learn something every day, cheers
To do this for specific sections go to Playback, Render Cache, User. Select the clips you want to render, right click, Render Cache Fusion Output > On
Dude. Just when I thought I had everything dialed in, but my ca.....che is st.....ill redn.....der.....ing lik.....e th......i.....s.....
Thanks!
Thank you so much! This is very helpful.

h.265 is better if you have the option for proxy media, half the file size for same quality
This super helpful. Just to add clearing out that cache folder every so often is key along with these settings. If you don't you may run into an error that will say "critical error" and won't allow you to make changes to projects while open and will repeatedly happen if you have backup saves on a frequent timer. It's essentially a warning saying you may have run out of space (ask me how i know LOL). The error doesn't really make it clear that this is the cause but every few months if i'm not clearing out that cache folder I run into it. Anyways Love the content and plugins!!
thank you
4:55 THAT is the ticket. I came here looking for exactly that breakdown. Just didn't know which compressed option to use. I gather this doesn't impact the final render in any way either. I can't believe I had 600GB of files on my NVME with a few minutes of fusion effects.
haha I came back to this because I forgot to 'save as default' so a new project hit me with a 400GB+ cache... thanks TWICE for this video.
This is a great tip, thank you!
thank you it was so helpful
thank you fam
For some reason DNx formats cannot be played back smooth on my RTX3070ti. I am not even talking about 8k. Even 1080p is a struggle. So I use h.265 proxies and intel quick sync to make it smooth. And effects I do render in place with quicktime argb format.
I've been using the highest version of DNxHR, but might switch down to the lowest.
Also, you could play with the resolution if you don't need high quality playback while editing. I only ever use half the resolution of my 1080p files.
Thanks bro
I've been using the program for a few weeks now and when I looked at my hard drives I noticed that I only had 30GB left. I kept wondering what happened and started deleting games and looked at my hard drive again and thought to myself...that can't be right until I accidentally found the cache folder!
thats why i installed an extra ssd for cache only(proxy drive)
Great tips! Thanks.
Very good video, Thanks, I will those settings and clear my cache. I was wondering the other why my media drive is at 95% full. ;-) Now I know.
Just Deleted all my CACHE FILES (Took 20 minutes) I recovered 332 GB on my 1TB Samsung 980 NVMe SSD C:\Drive. I don't do any Fusion or Color Correction. It's never been cleared Fully in 4 years. Thanks thought I was Going to have to BUY a 2TB SSD. You just saved me a couple hundred Bucks BRO.
with 10 bit uncompressed, the system does not have to compress and decompress the files before they are displayed and is therefore the fastest. The speed of the SSD is usually not the problem.
thanks. i just cleared bc of this 500GB of Cache out of my Stuff... Thanks
Give a Setup Tour! and How GTX 1660 is Rendering in 4K 10 bit? Is Your Hardware Setup Changed or Upgraded? 🎉🎉🎉🎉
why always 30 fps? also on "deliver" you set it to 30, why not 60? btw my main videos is Shorts/TikToks
4:45 - Personnel timestamp for when I do the next fresh install
641G of render cache haha 😂 Thanks for this easy understanding of how to fix it! 🙏
DUDE, YOU ARE A MAGICIAN!!!
I just cleared 40 Gbs of data that I didn't know even existed.
1 quary though... The play all frames seems to be very handy. But can you make a video about generating render cache for fusion page itself.... my fusion page playback seems very slow. Can you please help me out?
hello mate, i had serious problems with resolve , all of my problems cause by render cache on, cpu gone insane 100% and 90c degrees !!!!
when i disabled this my problems were fixed
Thanks for this video Patrick. As my resolve compositions are getting more involved then slowing down was becoming more of a problem. Hopefully not now I've got your insights.
I don’t use the cache at all.. anything that struggles, I just render in place. If I change video size, I will change the size then render out the video and bring in the rendered version that will run smooth. When you change resolution of a video to your project settings, it might lag unless you render it out first. The cache just causes all kinds of problems from black screens or whatever, ever since 18 came out. Hasn’t been fixed yet, far as I know.
@Patrick Stirling I am new to Davinci Resolve Studio 18.6.4 Just wondering how much storage needed for cache as in 4k h.265 fps 30 to 60 fps not often doing long recordings with effects and color grading as well?
yep, just cleared out 20gigs worth of cache. THANK YOU
Bro, no wonder I've been having so many issues with caching stuff, I don't think my computer was built to deal with uncompressed footage XD
Hey Patrick. Am planning to use a separate dedicated SSD for cache files. But was wondering if a very high speed nvme ssd would be overkill. What max speeds are the cache files read at? What speed SSD do I really need? Will 3500MB/s be more than sufficient or do I need more? Thks. BTW thks for this video. Its very very helpful for us novices. 👍👍
Hi. Can anyone please help me with my query? Can I get a 1 TB NVMe SSD and partition it, using one partition for the OS, and the other partition for the Cache files (Davinci Resolve). Are there any drawbacks to this? Because I am getting a high speed 1 TB Nvme SSD very cheap and so was thinking of partitioning it like I mentioned. Thks.
686gb....I was just picking delete unused cache in order to get more room
Thanks
Can somebody help me? After rendering (even several soconds video) the result is, that file cannot be played. It looks like only some file of cca 50 kb apperared. Anyone know what does it mean? How to fix it?
Hello. I need your help asap. I have been having issues where after editing an event video and then after the rendering is done, the output file only plays a section and gets stuck around the middle point. Have you experienced that? How do you resolve it?
thank you, protoV2 almost blew up my RTX4060 even in just 1080p
But if you have longer clips thjat few seconds.. like 1 hour video this caching takes huge amount of time and space. No other way to make it faster ?
That "save as default settings" in the last (timeline settings) was surprising for me after 7 months of DR instalation!😂
I think the best form to improve the playback is use the resize node to playback at 720p
👉 4:13 where it's at
my cache folder was 1TB, whoops (and I had HQX selected)
With SMART render cache settings... my RED render bars doesn't change to BLUE, any suggestions?
Hey, I make videos on DaVinci since 3 months and have all the time big issue - render crash, i made a many changes in my render settings some guy tell me to use render cache to neutralize opportunity to crash. In your professional view it will help with render crashes?
But anytime I have to make an edit, cut a clip etc I have to render that clip all over again ??
So time consuming no ?
Less than a minute of video produced almost 5 GIGABYTES of cache data. That's insane!
I guess that the high quality cache is there for those people who want to speed up render time by using cached images on the delivery page
Wow. I have over 300GB of Cache. Deleted 2 years worth and my playback alone is smoother
I did try out the render cache thing few weeks ago. Was working on a 1h video and Davinci decided to create 220GB worth of render cache that I had to delete later. Now I know why XD
Great man. This is what i was searching for. I want delete all render cache but there are projects that i'm not finish. Can i delete or it's a problem? Ciao from italy.
Every New User to DR when first time Downloading DR there should be a WARNING that DR will not Preform Correctly until all PREFERENCES & Project Settings have been Accomplished Then Directed to a video on how to accomplish the adjustments to DR. This will/would save Beginners so much Frustration.
this guy just talks sooo much in this video that its just un-needed
Very good vid. Explained this well!! Thank You!!
Thank you for the help you are awesome. I always assumed render cache was just bad and that it cause me problem.
My render cache seem to default to "none" every time I start a new project, can that be changed so it's always at least "smart" ?
Resolve should do that Automaticly, instead of making it hard to save space
It was some awesome stuff that I did not notice by myself. Thanks big bro!
Deleted 56GB of dvcc files
unfortunately the render cache is ignored when you switch playback resolution to anything else than full. This makes fast effect based editing and especially previewing without constantly rendering the cache in full resolution for all clips you want to preview impossible. We're using the latest 18.5. beta 2 version and have not found any workflow solution for this at the moment. The support could not help us either, which is really unfortunate, since this is a major flaw in DaVinci and makes it impossible for us to use it for our projects.
I didnt know what to do so I bought an additional 500gb storage to create a project. Is that correct?
REALLY THANKS a lot. That's why it was better without caching
Hi, I applied this (changing Uncompressed 10-Bit) and it worked. However, it seems the red dashes return every morning when I re-open the project in which I have to wait for it to finish (15 minutes) Is this the way it is? or is there an additional trick? Please advise, thank you
Hmm that does seem weird. It you don't change anything after saving and don't delete the cache files it shouldn't need to re-render them...
My default render cache fromat was ProRes 422 HQ hmmmm
How would changing the cache to DNX affect color grading? I imagine it would cause artifacts that could affect your grading process
Is it okay to edit my 4K footage in a 1080p timeline? edit and grading that way and then change the timeline resolution to 4K for export when im done? My computer can handle editing in 1080p without proxies.
Yup go for it!
@PatrickStirling thanks a lot !
You didn't mention that the render cache should be on it's own separate drive for the best performance. In fact, everything should be on separate drives . . . OS... READ MEDIA FROM... RENDER TO... CACHE.
Videos like this constantly say they've got a good computer. But we're never told what you have. So what are you using. Include memory, processor, graphic card including graphic memory on the card, and the type of drives you have. Also, which version of DaVinci and if it's studio or the free version. Any one of those things can make a difference in what you're doing.
I was just on another website that said you should have different drives for your cache, project and so forth. I have no idea if it does or not. All of yours are on your C drive.
sir, you just saved my life
