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

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.

Good stuff. Thank you for not having background music. You're legible and concise.

Thanks for sharing. Thanks to you and a few other KZfaqrs, 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.

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..🤯

Very important info 👍

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.

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

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

Bruh 2,037 GB deleted

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

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

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.

This could not be more helpful. Thanks man!

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

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

One of the best to do it!! Thank you 😊

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!

Thank you for this video

Unbelievably helpful - thank you Patrick 🙏🏻

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

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

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!!

Thank you, saved a lot of further headache. Big like bro! 😎👍

Thanks. I wondered why certain projects were slowing down.

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...

thank you so much!!!!

Bro your so cool thanks man

awesome and helpful content Patrick thank you so much

Thank you!

Omg I was doing the whole cache thing wrong and the first tip omg that is the big one bro 🧠

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!

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

Excellent tutorial, thanks!

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.

wow 93gb in mine, didnt even realise at all

Damn got my 200gb back thank you

Thank you so much!😊

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

Very nice vid as usual.

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

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

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

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

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.

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 ???

10gb cleared 👍

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

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

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

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 :(

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.

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

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

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.

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?

Do you know if this can be done on iPad?

Jordan Peterson : clean your room Patrick : clean your cache

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!!

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!!

it would of played just fine on an Ipad though.

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

Why did Resolve never fixed that mistake. A flaw to me

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?

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.

I stopped using render cache just for this 😑
