Thanks for sharing. Thanks to you and a few other KZbinrs, I am hooked on fusion! I work in fusion to relax, it's just crazy! I don't know even what to do with my creations! Thanks again for making these things seem that much easier.

[@GaryCunninghamyouareenough]

Unbelievably helpful - thank you Patrick 🙏🏻

[@DaRalf23]

I honestly just thought it was something Resolve did, figured it wasn't optimized or my computer wasn't good enough. This is really exciting to learn.

[@sergentboucherie]

When you are in the Fusion page bottom right you will see a percentage and a RAM amount, you can right click that to purge your comp’s cache and have a few more options, sometimes in Fusion the cache gets confused and it will show a mix of cached and uncached elements together

[@billythecat]

hi i tried to right click that and select purge cache to free up some ram but nothing happened?

I just learned this the other day cuz I was having troubles with an image loading. Very useful information to have!

[@blackmirror0098]

That finally made things clear about render cache. A very helpful video guide. Thank you.

[@mcpaddock_de]

thank you so much!!!!

[@andy_knight]

This is super helpful, thanks Patrick. I added some background blur using the depth map and the playback was awful, I'll try this out!

Learned something in the first minute that will help me immensely. I have been doing this wrong for a while. Thanks.

[@ankushishere]

All i can say is thank you so much really thanks man have been dealing with this for a long time.

[@PatrickStirling]

this exact issue? that's amazing if I was able to help clear this up for you 👊

[@TheRealBarkinMadd]

There are so many other caching mechanisms as well such as mode caching on the Color page and in Fusion. Would be wonderful if you could go through those as well (including strategies for when to use them). Thanks for this one, Patrick.

[@reelhawksstudio]

[@JeremyChone]

Very nice vid as usual.

[@ATLJB86]

First tip was very helpful and probably why I’m have issues with smart mode. I set to quarter and smart but what happens sometimes is this.. After the smart render is done, when I start to make certain changes, it seems like is stores the new cache with the old one and playing both at the same time. So i get strange colors, weird lines, or completely black screen. Then I have to disable smart, delete cache, then re-enable smart and re-cache for it to play right.. I have been working counterproductive to how the cache works this whole time..🤯

[@theplussizecostumer]

Thanks. I wondered why certain projects were slowing down.

[@RealTimtationz]

You just saved me 315 GBs with the clearing Cache tip.. THANK YOU

[@thomasmosby1231]

Yo! I went to delete my cache. ....473GB!!!!!! OMG! Me and my hard drive THANK YOU!!!

[@buzzdx]

you can also achieve the "forced caching" you showed at the end without any changes by playing the clip in the color page.

[@leotexas3485]

Ohh wow! I kept running low on space and DaVinci kept crashing, even after deleting all my render cache on some of my larger projects; still, I would soon run out of space. Using this method and manually deleting the cache from the folder just freed up 640 gigs on my 1 TB hard drive! 😅😃 Thank you for this!

[@Xionaxyz]

Hello from NZ Patrick, thanks for sharing your hacks. Could you please do a video (sorry if you've done already), about setting up good habits for organising and naming cache folders for projects so we know what we're deleting? I know you mentioned DR regenerates new cache clips (mind blowing) but I feel like I need to evolve with DR and be more responsible and respectful, rather than grinding on one new project after another, only to find myself back on YT hunting for a solution. I've been doing this since DR7 lol. Also, thanks for getting straight to the point in your videos. And your humour is refreshing during stressful times...

[@fariscosta4167]

Lol I've just discovered that I had 235GB in my CacheClip... Thanks for this video man, you're a legend!

[@lucabastianello9830]

I needed such video 3 week ago when I found my project with irreversibile error project and thakls to turnaround I deleted my main timeline, puckyly I had a rendere gli of it ended. Only to after fino out that my ssd had 400+ gb worth cache fron DvR and it was the problem. Solved the problem, still this is useful video

[@caribemediaproductions2236]

Thank you, great video, i have the M1 Max. I am rotoscoping in fusion on a 4k raw image, kinda need good playback to see if the scope follows the footage. Its not going smooth on my macbook M1. The mask is not updating always and I need to click a corner of the mask every time for it to update, and sometimes the mask is updating but the background image is not (stuck). Is there a way to make this work better?

[@JustinDaniels]

I don't like setting timeline resolution to anything other than full, because if I need to zoom in on the viewer, I want to see everything in full quality as I edit.

[@fabislav]

for me it was render cache format (idk why i had 10bit uncompressed selected, switched to DNxHR SQ) :D with my setup i7 8th gen + gtx 1080 I do 4K videos and sometimes superscale for drone footage and it´s not pain anymore, fr try switching the format

[@chiranadevsath8315]

Damn got my 200gb back thank you

[@eddiep4940]

Hi there, many thanks for the video. I have everything setup, but when I go to the delivery tab, and I try to play the video, I get this error - Critical Exception: Bad Allocation - any ideas on how to fix this, as I am not able to go any further

[@photojoseph]

Very helpful. Still my number one feature request for Resolve is a “render cache” command like FCP has. Just select anything, hit the shortcut, and it caches. So seemingly simple!!

[@PatrickStirling]

Absolutely. While the Color Render cache is functionally that since the color page is the last link in the processing chain, that's a little more confusing and I think it still requires you to select the option for individual slips in the context menu...

[@photojoseph]

@@PatrickStirling yep. Super non-intuitive and not universal keyboard shortcut away. I will pester them at NAB.

[@satyamdograreallife]

Hey Patrick When I get to Working Folders for deleting Render Cache. It shows Cache Clip Only. It doesen't show which drive it's Located in, although I have only One Drive in my Laptop & that's a c-Drive. Still finding it in another Viewer doesen't show me that CacheClip. It's neither a Folder in my Drive neither I can find some like that in my BlackMagicDesign Folder. What Could it be ???

[@JasonAdank]

So is there any solution to insane lag when youre just workign with footage on the edit page? I dont have any fusion comps going, but even though my timeline is cached (blue line), it staggers horribly and i cant edit the footage for timing or to music because it stuttering so bad. My cache is set to smart, Use Optimized Media if Available is enabled. Im not sure what else to do.

[@killamane.1]

Do you know if this can be done on iPad?

[@brettbertini]

just cleared 500GB of cache files I was unaware I had lol

wow 93gb in mine, didnt even realise at all

[@oxygen454]

10gb cleared 👍

[@imMXND]

Alright, but i'm caching the video and my resolve just crashes... What can i do to prevent that?

[@mamamia980]

can you make a tutorial on how to make Davinci resolve templates. I want to make some for myself but don't know where to start

[@PatrickStirling]

see if this gives you what you want. might be a little more detailed than you want as it's built around a larger presentation: kzbin.info/www/bejne/r3XQgIBund5qb6c

[@yamz3626]

So if I delete all the files from CacheClip Folder, Will it ruin the whole video I've been working on so far? it already took 60 gigabytes :(

[@bobstark8749]

It shouldn't. DR will recreate the cache files according to your particular settings. I had to do that too. My cache drive was full and I cleaned out a bunch. Check your project backup settings for backing up as you make changes. This will ensure your project is backed up and you can pick up where you left off. If you have to load your project from an earlier backup you should be good to go if your media files are all in the same place. I had to do that too. :)

[@Luddejonassalle]

does anyone know if it makes a differance having the cache files on a ssd or a hdd?

[@bobstark8749]

Yes, it does makes a difference (imo). Use ssd drives for your cache files if you can. A separate ssd drive for your cache files would even be better. SSDs have faster read/write times than hdds. This is important for low latency response in the video editing and creation processes.

[@annabrouckova2247]

so what do you actually delete when you delete cache? isn't it dangrous to losing data of the cutting process or someting?

[@PatrickStirling]

You are deleting the video files that are generated to give you smoother Playback on the timeline. Those files aren't used in export unless you specifically tell it to, and deleting them should only really slow you down if you're cutting a video with lots of heavy effects, but then you'll just have to wait until the cache for those specific files regenerates.

[@IskyIskandar]

render cache is ignored at any other timeline proxy resolution than full???? 😫 is that only for fusion clips? or video too?? thanks for the video!!

[@PatrickStirling]

hmm that'd be worth a test, create a wild color grade that would require a cache but check proxy performance. it could always process that a little different behind the scenes..

[@PatrickStirling]

did a super quick text with a chunky color grade and it looks like that works as intended.. I actually wonder if this is a legitimate bug..

[@DaVinciResolveSchool-ur2ni]

Hi guys Could you tell me if I will delete render cache from my current project, then doesit affect it somehow? Like make some media on timeline off?

[@AK-Cat]

@@DaVinciResolveSchool-ur2ni It should say clear render cache, which won't Impact your project.

[@DaVinciResolveSchool-ur2ni]

@AK-Cat thanks buddy

[@AK-Cat]

@@DaVinciResolveSchool-ur2ni No problem bud

[@lensflareclips]

it does not seem to be possible editing with proxies set to quarter resolution and having render cache active at the same time. Once you activate render cache it renders at full resolution. If you have a scene where you can't playback smoothly even with quarter resoluaiton proxy you can only use render cache. That works for this scene, but you then need to switch back to proxy quarter resolution and this scene will stutter although it has been pre-rendered.

[@bzibubabbzibubab420]

Sama case , this is frustrating tbh

[@JustinDaniels]

Resolve's cache is so large that I have a dedicated 500GB SSD in my system simply for cache.

[@HiItsSalty]

Thanks, I thought it was the whole folder, but i just cleared out 50 GB and i ONLY edit shorts LOL

[@dpjohnjones432]

Man I wish I had seen this a week ago lol. I actually returned a M1 MacBook Pro because I made these exact mistakes.

[@nagruvajse]

still this say nothing about a solution to a major problem, when everything is rendered and you move one little thing, lets say ive cut some frames out of one little clip, or i did a fadein or some effect, EVERYTHING goes in red and is in need to be rendered again. its MEGA annoying

[@marc3793]

Really useful. Answered a lot of my questions around slow render times which using Fusion Effects too. Does anyone know a way of setting "Render Cache Fusion Effect Filter" for multiple clips at once? Even if you select multiple it only applies it to 1 clip.

[@ChuchoTheCatLord]

haven't even finished the video and already found 99.7gb in CacheClip folder... sneaky bastard render cache... I'm only working on crappy .. 1080p yt shorts... WOW! EDIT: Thanks much!!

vegas does not need cache it just DOES whatever you want. I've been using vegas for 14 years and I have NEVER had a single crash

[@ProgrammistMusic]

the render cache system, especially in combination with the proxies is one of the worst i have ever seen in a video editing software. Not being able to use the render cache if the proxy render resolution is not set to full it totally unacceptable and makes fast effect editing impossible. This is the only thing, that Adobe Premiere still handles much better.

[@schmutz06]

thanks. I came here because my render cache for a 1-2 minute video in 4K hit 600GB and brought my NVME SSD to it's knees; so I had to learn about it and this vid was helpful. I have noticed 'render cache format' is set to uncompressed 10-bit, hence likely why my cache is gargantuan size. I am going to explore (other YT tuts and experimenting). I used Adobe AE for 15+ years and I'm loving Davinci Resolve, whilst also finding all my intuitions are taking an ass kicking. I'll get over it.

[@MachineSupremacy]

I stopped using render cache just for this 😑
