Hi,
I'm trying to convert a TIFF image sequence into JPEG (sequence) for
preliminary video analysis, and I need to save the JPEG using yuv444 or
yuv442.. but all I have achieved by now is the simple TIFF to JPEG
conversion with some setup in the quality setting (that still produce
blocky images, even with -q 1 or -q:v 1)..
Also, the only codec that works is the MJPEG, any other codec produces
unreadable images or extremely slow-to-process images (libopenjpeg)..
Please post the command(s) you're using, including the full, uncut command
line output.
