[FFmpeg-user] Is it possible to convert yuv444p10le to gbrp10le without defaulting to rgb48le ?

[Suria Pang]

Both window and linux version are giving this issue:
 
ffmpg when convert prores to dpx always default to rgb48le which yield 12M file size wilie standard HD 1920x1080 dpx are gbrp10le at 8.6M.

Is there anyway to get ffmpg to convert yuv444p10le to gbrp10le   ??
 
Here are the output and thanks,
