FFmpeg AVIF Format

[jay123210599]

When making AVIF files from videos using ffmpeg, do they automatically get the right format for it? For example, if my video is YUV240 8bit or YUV444 10bit, will ffmpeg automatically use the correct format for it?

Can't you just fucking fuck around and find out
It's not like FFmpeg hides what pixel format it uses from you
What the fuck is wrong with you

Short answer is yes

Well in that case, since my source video does not any colorimetry flags, I'll just use this since the output AVIF won't have any tag issues and it automatically get the correct format.

-vf zscale=min=709

But my problem now is that I got this error

[Parsed_zscale_0 @ 00000295523f9340] code 3074: no path between colorspaces

How do I fix this while getting the 709 colors I want?
