[FFmpeg-user] YUV->RGB Color Shift

[Bob Richards]

In 0.9 when transcoding from ProRes 4444 to a DPX sequence I am
experiencing a color shift that I believe may be due to the yuv-rgb
conversion.  I'm assuming ffmpeg does a video level scale/unscale
operation in these conversions by default but is it possible to
disable this?  I did try forcing specific pix_fmts and color_range
options without it affecting much change in my output.

Sample command:
ffmpeg -i input_prores.mov -vcodec dpx sample_seq_%03d.dpx
