YUV444 source "Converting input clip to YUV420"

[Ceppo]

I'm trying to encode a 444 16bit clip with x265 but it gets converted to YUV420. How do avoid this?

Try adding

--intput-csp i444

I tried adding --input-csp i444 but with no changes.

Maybe you should try setting the profile accordingly with the --profile switch?

With --profile main444-10 --input-csp i444 still no luck.

The problem is in your avs2yuv call. You have to use --csp i444 as the default is i420.
