I tried the scale command with the 10 bit build, but no luck. Resulting video was one uniform color rather than 8 distinct bars.
Possibly because it did work but every video player by default will assume limited range for yuv so stretch and not display anything above/below the video levels. It will also be pot luck whether by default you will get to see 10 bit 444 or whether the player ends up converting it to 8 bit 420. FWIW using your 1.png I can convert to full range yuv44410le and back to png and the result is very similar to the master (=+1 on the values as shown by imagemagic display). Squashing to video then expanding back to png48 there was more of a difference = +12. I didn't test zscale yet and am just "clicking around" to see numbers rather than judging ramp smoothness (not that 1.png is a ramp anyway). _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
