Comment (by ponpon):

 thank for your reply and pointing out not enough explanation.

 >You wrote above make a beautiful RGB or YCbCr video.
 yes. thank you for your understanding regardless of vague explanation! ! !
 Lab color space produces its effect in filtering rather than pix_fmt of a
 final output.
 as you know, ffmpeg can change pix_fmt in video filter.
 difference, a case of unsharp

 >Could you elaborate?
 i done with a trial version of photoshop before. photoshop can import and
 modify a movie, though it is little is known concerning.
 now i can't use photoshop because the trial version is expired and it is
 too expensive.

 >Are you talking about gif files?
 not only gif but also mpeg2, mp4, mkv, etc. because Lab color space
 produces its effect in filtering.
