Please Change This Render Cache Setting Right Now 

Just cleaned-up 400+Gb of cache clips, this is insane. Thank you very much Patrick!

Davinci Resolve suddenly stopped rendering my projects 5 days ago. After watching other RU-vid 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! ☺👏

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!

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.

You can also create proxies (lower quality clips used just for editing), there's great tuturials out there on that

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!

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 😂

You are Absolutely Right! The average, Hell even the advanced Professional RU-vidr 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!

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.

You stop it… FIRST! ❤

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!!

Not sure why RU-vid recommended this video to me 11 months after it came out but I'm glad it did. Working on a vid where I'm using learning to add effects, including your Proto V2 Effect plugin. It was taking quite a while for the effects to render and was still a little choppy during playback. Changing these settings helped a ton. Renders is seconds and playback is smooth. This computer is getting old and I'm glad I'm not having to replace it yet.

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.

Another fantastic thread on making Resolve more responsive, Thanks Patrick.

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.

I'm halfway through the video and i can already see results. Is thanking you even enough ?

Patrick…THANK YOU SO MUCH FOR THIS!!! I knew about the cache stuff but the settings have improved my systems performance dramatically!!!!!

After countless videos on this that were wrong your video just saved me and i got my video exported. I had so much masking it wouldnt even begin to export. After using the smart render cache and remasking it worked no problem.

I was making a 4k video 5 min long and somehow used over 300 GB of Cache, this fixed my problem instantly, thank you for this!

Showing all video frames: just what I needed now... Good timing Patrick .

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.

Very useful bro!!... just cleaned 200gb thanx ur tip!!... Gracias from Chile !! 🙌

It was some awesome stuff that I did not notice by myself. Thanks big bro!

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!

How is this not a first step 101 for new users? Holy cow, game changing.

sir, you just saved my life

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!

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.

I didn't know I needed this vid. I am working with very little hard drive space. I didn't realize I had 40Gb of nonsense cluttering up my very valuable space.

Very good vid. Explained this well!! Thank You!!

Thank you very much.Decode thing works for me because i use clips taken from iphone :)

You are a legend with the save preset as default. Thanks so much.

Great tips Patrick. Just been in, tweaked my settings and saved as default 👍😊

Thank you for the help you are awesome. I always assumed render cache was just bad and that it cause me problem.

I use h265 for proxies and ProRes 422 Proxy for everything else. I work on a low-budget system with not much storage space. I also force temp media size to HALF size. Largest video dimensions I use are 4K or sometimes Open Gate 6K

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.

I just need this video , love you Patrick :D

New to DaVinci and to your channel, massive thank you for solving some of the problems I was experiencing!

Super helpful and excellent explanation. Presentation was clear and conversational which makes it easy to watch and follow along.

This video helped me so much thanks a lot man🤙🏼🔥

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 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!

I'm glad I found your video, I'm fairly new to Resolve and I didn't know much of this. Thank you!!

These are all hidden stuffs for starters - thank you for sharing

very informative! thank you for this

Mannnnn!!!! Thank you sooooo much bro!!!! I had over 140GB worth of cache files on my hard drive...smh... I was finding myself deleting and xferring files off my laptop to make room for projects I've been working on... I appreciate this information!!! #Salute

That "save as default settings" in the last (timeline settings) was surprising for me after 7 months of DR instalation!😂

So you changed my life with this video... thanks

Thanks Patrick!

This is exactly what I was looking for!! Thank you!

Yup the last one was insane! I had more than 300 gb occupied by DaVinci for my RU-vid videos 😂 insane! I even turned off cache media

yep, just cleared out 20gigs worth of cache. THANK YOU

Thanks for this!

DUUUUDEEE You just saved my life! Thank you so much

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).

O. M. G. I was getting corrupted edits because of this. 298GB of garbage cache clips. Thank you for this!!

Thanks mate. Can you please do a detailed video about what is (as is not) actually included in projects, databases etc. Also the process for backing up projects / databases elsewhere (and restoring). And also save so can get new drive, reinstall windows and then restore all Resolve stuff as it was. I get pretty confused about all those things. Ta

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.

I think the best form to improve the playback is use the resize node to playback at 720p

Patrick, thanks a million. I'm a new subscriber and I've been making RU-vid 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!

thanks man my videos were getting like 5 frames in the edit page!

Great video! Time to look under the hood in DaVinci🎉😊

i saw this happen to myself a couple days ago. had to look for the cache folder and deleted it. 100 gigs gone lol. going to roll with the SQ format now, that was a new tip.

Bruh this saved me so much. I had 2.5 TB of cache files which was just ridiculous.

Bro you saved my life

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.

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

thanks

So you have to make sure your effects are all blue or they wont render out?

Brother! Thank You for this video :) My hero!

This video is such a life saver!

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

This is simply brilliant! I just freed up 450gb of space after following your trick. Thanks !!!!

REALLY THANKS a lot. That's why it was better without caching

Thank you thank you!

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.

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.

thank you, protoV2 almost blew up my RTX4060 even in just 1080p

4:45 - Personnel timestamp for when I do the next fresh install

I can't thank you enough, this is a life saver

Thank you so much! This is very helpful.

Thanks!!!

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?

thank you it was so helpful

686gb....I was just picking delete unused cache in order to get more room Thanks

Thank you Patrick, I'm editing on an 8 yr old PC and even a small fusion preset will bog down my playback in the timeline, I was working in proxies, but figured out I don't think presets get made into proxies, only the footage? Anyway, there were a few setting I was missing, like the uncompressed and optimized media settings. Great tips, tyvm.

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.

Thank you it helped me :)

thank you

thank you fam

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.

Thank you for this Patrick. I had a 1tb SSD that had one 1% left! Not anymore though.

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...

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!

Thanks for the tips!

This is a great tip, thank you!

Greatest video about it!!

Thanks for a very helpful video.

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!
