Lossy WEBP Colors

[jay123210599]

I want to make a lossy (yeah, you heard that right) animated WEBP file, but I also want it to have the same colors as my input video. How do I do that with ffmpeg or some other tool? How do I achieve very high quality for lossy webp files (both still and animated)?

lossless.
lossy compression at very high quality like crf 1 is often bigger then lossless crf 0.

you don't ask for the best on this forum because there is no answer.

What should the command be for very high quality lossy animated webp for ffmpeg? Are there any tools that could do the trick?

-quality 100

What about this?

-lossless 0

Something along the lines of:

ffmpeg -i INPUT -lossless 0 -quality 100 OUTPUT.webp

The lossless switch is not strictly necessary because, by default, it is zero.

I mean -lossless 0 by itself, without the -quality 100.

What if my inputs are yuv222p or yuv444p videos? Will I still get the same colors if I use lossy webp?
