ffmpeg-20191101-53c21c2-win64-static\bin\ffmpeg.exe -h encoder=v210
Encoder v210 [Uncompressed 4:2:2 10-bit]:
    General capabilities: none
    Threading capabilities: none
    Supported pixel formats: yuv422p10le yuv422p

The encoder does support this format, without conversion. It is even the only format it supports, along with its 10-bits counterpart.

[Carl Eugen Hoyos]

I am not saying that yuv422p support should be removed but I believe it is noteworthy that no other encoder does internal colour space transformation which comes in addition to the change of input data for a codec that users believe is lossless...
