[AnimateDiffEvo] - WARNING - ffmpeg could not be found. Outputs that require it have been disabled

[evanerichards]

I keep running into this problem: [AnimateDiffEvo] - WARNING - ffmpeg could not be found. Outputs that require it have been disabled

I don't know why it's giving me this message as ffmpeg is definitely installed on my system and a PATH is even set in environment variables.

Any thoughts why this might not be working? Should I be able to export video files in addition to .gif and .webp? I've updated comfyui and all the associated nodes.

Check if VideoHelperSuite stuff works for you for video outputs - the video-related nodes in AnimateDiff-Evolved are deprecated and I will delete them in a few weeks.

[Kosinkadink]

Hey, were you able to get ffmpeg working with VHS? I just pushed some code here there that should fix ffmpeg use on certain OSs.

I have the same problem and can only use GIFs

Hello, same for me : [AnimateDiffEvo] - WARNING - ffmpeg could not be found. Outputs that require it have been disabled FETCH DATA from: https://raw.githubusercontent.com/ltdrdata/ComfyUI-Manager/main/custom-node-list.json Merci beaucoup !!

Hi, little feedback for MacOS (apple silicon), there is the same problem with ffmpeg, and we obtain a black picture when the generation is finished.

[ixiLod]

Regarding the installation on Mac, the installation via the official package does not seem to work, you just have to go through an installation with homebrew, with the homebrew installation the nodes recognize ffmpeg, however, you always get a black picture at the end of the generation.

[Kosinkadink]

If you're on Mac, make sure you apply the workaround to keep comfy's optimization from kicking in, as pytorch on Mac has a bug that causes black images when that happens: https://github.com/Kosinkadink/ComfyUI-AnimateDiff-Evolved/issues/48#issuecomment-1750156332

If you're saving a gif, it does not use ffmpeg at all to do it, so the images will not be black because of that. But the Mac bug does cause it. Soon(ish), I plan to make it easier to apply the workaround for the Mac pytorch bug.

[Kosinkadink]

Also, the AnimateDiff Combine node is deprecated and will get zero support going forward - I only still have it here for backwards compatibility with previous workflows. The continued development of that node happens in VideoHelperSuite, with the direct replacement node called Video Combine. However, if you didn't apply that Mac workaround yet, the black frames are much more likely caused by the bug than anything relates to ffmpeg not being there (save options available when ffmpeg is not found don't use ffmpeg to save).

[ixiLod]

For me I had the problem of black images with the latest VideoHelper and the deprecated version, I tried to put unlimited_area_hack=True, but now it systematically crashes at Sampler time, there must be something else, when I reset to False no crash, I will look into the question, and thank you very much for the topic, and especially for the work!

[Kosinkadink]

@ixiLod use the --use-split-cross-attention startup argument, that should fix your crash on Mac, on that thread I linked some other peeps had the same issue and fixed it with that

[ixiLod]

It works well ! Thanks a lot !

Hi everyone! I run ConfyUI locally on a PC and I get the same error message… I’m only able to generate GIF and not video outcome. I read the whole thread but not sure how to fix this. It worked with A1111. Thanks for your help 🙏

[Kosinkadink]

@abstrct90014 Make sure to use Video Combine from VideoHelperSuite (VHS), linked in the readme, instead of AnimateDiff Combine from this repo. AnimateDiff Combine is deprecated, meaning it will not get any more support. I plan to update the code for it to throw an error telling people to use Video Combine from VHS instead.

@Kosinkadink I'm not getting any black screens now, but I still get the warning about not having ffmpeg and only have gif and webm as output options. (Mac M1 Max) - is there someplace i need to put ffmpeg within the comfyUI folder for it to be regocnized?

[ixiLod]

@TheMGilroy Install ffmpeg with homebrew, it works for me, I'm also on m1 max :

brew update brew upgrade brew install ffmpeg

[TheMGilroy]

ah, yep that worked. Easy enough

[94352799]

[AnimateDiffEvo] - WARNING - This warning can be ignored, you should not be using the deprecated AnimateDiff Combine node anyway. If you are, use Video Combine from ComfyUI-VideoHelperSuite instead. ffmpeg could not be found. Outputs that require it have been disabled.

i cant repair help me pls

[Kosinkadink]

There is nothing to repair. If you're intending to combine your frames into a video, the warning explains what you should do. Is there something in that warning message that you need a clarification on?

[Gloynus]

How do you just turn off this warning? I don't plan to put ffmpg and use outdated nodes. I would like not to see 6 warnings in a row every time I start (I don't know why I have 6, but it's a fact).

[crystalwizard]

is there an updated node yet?

[Kosinkadink]

Yes, it's exactly what the warning message says.

[Postvoyagercl]

I did al the @TheMGilroy Install ffmpeg with homebrew, it works for me, I'm also on m1 max :

brew update brew upgrade brew install ffmpeg

and the Errors doesn't exist anymore, but the result is a black video. Any hint? I´m running M2 Mac

[Kosinkadink]

@Gloynus I pushed a new change just now to keep the warning from repeating on every page reload - I'm guessing on your end, you had duplicate warning messages pop up for each tab/refresh done, that should go away now - will only display the first time ComfyUI is accessed in the browser after a ComfyUI restart.

I'm a user of the M3 Pro MacBook Pro, and I'm still encountering errors when using SVD or AnimateDiff Evolved on this Apple Silicon Mac. I've installed ffmpeg via Homebrew, updated all nodes, and specified the path for ffmpeg. I'm using Stable-Diffusion via the ComfyUI package through Stability Matrix. For Mac, I heard there's an error with pytorch causing black screens in the generated output due to system conflicts, so I'm using --use-split-cross-attention. I've also heard that the Video Combine node in VHS is no longer supported. So, which nodes should I update to? I'm still experiencing ffmpeg errors and have installed mps acceleration and onnyxruntime to resolve mps backend out of memory errors. I've also used arguments like --precision full --no-half --normal vram and adjusted environment variables. Please help me out. 😭

Hello there, i don't if you still need help but, that's error message said you don't have the FFMEPG installed or set as default path, please follow this guide here " https://www.wikihow.com/Install-FFmpeg-on-Windows " and you will solve the problem. Hope it helps

[Kosinkadink]

That warning message can be completely ignored. I thought I deleted it in recent versions as the ancient video support in ADE is completely deprecated in favor of VideoHelperSuite. VideoHelperSuite works with either a manually installed ffmpeg, or tries to use imageio-ffmpeg package instead.

If I forgot to remove it, I'll do so on the next release.
