feature request: export selection as animated webp

[Diego851]

Hello

Please consider adding "export selection as animated webp", it would be useful.

Also it might be easy to add, for ffmpeg can do such conversions with something like

Code Select Expand

ffmpeg -i input_file.mp4 -vcodec libwebp -lossless 1 -q:60 -preset default -loop 0 -an -vsync 0 output.webp
Thanks
