Don't know what's wrong! :/ about eccv2022-rife HOT 6 CLOSED

You have to install ffmpeg. It was not listed in requirements.txt as it is not a python package.
http://ffmpeg.org/download.html
Also go into a console and check if you can execute it, you might not have it in your PATH environment variable.
Without knowing your system I can't give you any more detailed instructions.

Edit:
I should have figured out sooner you are on windows, you have the "Users" folder. Here is a simple guide how to do it in gui: https://www.architectryan.com/2018/03/17/add-to-the-path-on-windows-10/
You can use either the system or user PATH variable, of course 'system' works on any user, 'user' only on your account. Extract ffmpeg to any folder you want, e.g. "C:/Program Files/ffmpeg/" and add the path to the folder with the ffmpeg.exe to PATH. I believe it would be "C:/Program Files/ffmpeg/bin/" in this example, though I'm writing this from memory.

@TheHardew Nope, I am on Mac! Mac also has Users folder.

@kunwar-aditya I'm not really familiar with mac os, but this seems to be an up to date example of adding things to PATH there: https://medium.com/@grantbrits/editing-path-variable-in-catalina-mac-osx-5532ba447af9
That's also how you could do it on linux using zsh shell, so I think it should work.
Also, you might want to look into homebrew, it is a package manager and it would allow you to install ffmpeg like this: brew install ffmpeg

@So-Yp did you edit the python files used for interpolating video to switch to a different encoder? ffmpeg uses libx264 (notice the x in between). I'm not sure what's the problem with opencv though.

@TheHardew Yes, I tried to edit the H264 encoding of the python file, but the code reported an error
OpenCV: FFMPEG: tag 0x34363278/'x264' is not supported with codec id 27 and format 'mp4 / MP4 (MPEG-4 Part 14)'
OpenCV: FFMPEG: fallback to use tag 0x31637661/'avc1'

@So-Yp change line 82 fourcc = cv2.VideoWriter_fourcc('m', 'p', '4', 'v') to fourcc = cv2.VideoWriter_fourcc('h', '2', '6', '4') and when executing the script add --ext=mkv. This seems to work for me (I hope I didn't forget any steps). If you really need mp4 you can after that execute ffmpeg -i a.mkv -map 0 -c copy a.mp4. I'm not yet sure, how to change encoding settings. By the way, you should open a new issue for that, so we don't spam here.

Edit:
By changing fourcc to 'a', 'v', 'c', '1' you can keep mp4 extension.

@TheHardew ok，thanks
