Comment (by spookybathtub):
Alright, tried that. The RGB conversion is not the problem. The
following commands produce identical files, both of which look different
than DaVinci's:
{{{
ffmpeg -i J001C031_140110_R6MS.mov -an -vcodec v210 -vf
"lut3d=file=LogC_to_709.dat" Jv210-LUT.mov
ffmpeg -i J001C031_140110_R6MS.mov -an -vcodec v210 -vf
"format=pix_fmts=rgb48le, lut3d=file=LogC_to_709.dat,
format=pix_fmts=yuv422p10le" Jv210-rgb-yuv-LUT.mov
}}}
One other variable here is that DaVinci works in 32 bit float. Perhaps
that accounts for the difference?
