ffmpeg MOV to Animated WebP

mov2webp.sh

ffmpeg -i input.mov -vcodec libwebp -lossless 1 -q:60 -preset default -loop 0 -an -vsync 0 output.webp

@dreampiggy, How can i set a export video resolution?

example the video i have is 800px height and i need to 480px webp file.

@vijkmr somehow like that I guess:

ffmpeg -i video.mp4 ... -vf scale=320:240 output.webp

Thanks @scpketer, i tried this and it worked

ffmpeg -i input.mov -vcodec libwebp -lossless 1 -q:60 -preset default -loop 0 -an -vsync 0 -s 320:240 output.webp

better gist -> https://gist.github.com/witmin/1edf926c2886d5c8d9b264d70baf7379

-q:60 should be -q 60

ffmpeg -i input.mov -loop 1 -an -vf scale=750:-2 -r 24 output.webp

ffmpeg -i input.mov -loop 1 -an -vf scale=750:-2 -r 24 output.webp

tried this in May 2025 and it works

Hi, it works nicely but, do we have a way to retain the alpha channel from the .mov ? the terminal says this :
alpha is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented. i wonder if it's already supported and i didn't put the right command into the line you provided ?
