YUV444 source "Converting input clip to YUV420"

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

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

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