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

Hey,

I have tried your method several times with a gazillion different adaptations to the settings...
Any idea what i'm doing wrong, for some reason, my new frames are rendered over the old ones...

I uploaded an example here: https://drive.google.com/open?id=1ICZ-CJ9Ug_Y4fCsmJjsEd_QHho1qXKoC

Found someone else with this problem, but it didn't get resolved:https://stackoverflow.com/questions/38864497/transparent-animated-webp-not-clearing-frames

Thanks!

@FlorianHendrickx1 +1

The following command works in my case. You can have lossless or lossy options if you want. I removed -q:60
ffmpeg -i input.mp4 -vcodec libwebp -preset default -loop 0 -an -vsync 0 output.webp

@FlorianHendrickx1 I couldn't find an FFMPEG solution for the same task either. So, as a workaround, I decided to render .mov as a png-sequence with alpha channel and then pass it to the img2webp converter (https://developers.google.com/speed/webp/docs/img2webp).
For me it works like a charm.
Hope it helps.

@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
