Comment (by cehoyos):
I tested the following with kdu_render 7.6:
{{{
$ ffmpeg -i fate-suite/jpeg2000/chiens_dcinema2K.mxf -vcodec copy -f
rawvideo -vframes 1 out.jp2
$ kdu_render -i out.jp2 -o out.jpg
}}}
Using FFplay to look at both files, out.jp2 show a brown dog, green
background (leaves) with brown trunks and several red elements on the
laptop screen. The file produced with Kakadu, out.jpg, shows a grey
background, grey laptop screen and a very light brown dog, nearly no
colour.
What does Photoshop do with the exported frame from chiens_dcinema2K.mxf?
