Do you think that FFV1 'lossless' video codec is a real lossless video codec? I have serious doubts. At first I used (and later other 3 transcoders) to transform AVCHD MTS (progressive segmneted frame) camcorder files into FFV1 MKV format. I tried 4:2:0 planar 12bpp and all avaiable other higher FFv1 options. They had the same results (( The png photos were taken by from the video-frame: 810 th. The original camcorder file (179 M.byte only) is located here: Photos: Seach the difference in the red square! (please, download and enlarge them in a photo viewer application) Original MTS file: (frame: 810) The FFV1 file: (frame 810) I red an article, which proposed the unecessary color palette conversion as the cause of quality losses.

But it is not beliveable: Have you got any idea or suggestion about this 'lossless' quality problem? The didn't produced that quality problem. Thank you for your reply! Code: v1=ImageSource('1.png', start=0, end=10).ConvertToYV12() v2=AviSource('1.avi') sub = v1.subtract(v2) substrong = sub.levels(112,1,144,0,255) StackVertical(StackHorizontal(v1.subtitle('png'),v2.subtitle('ffv1')),StackHorizontal(sub.subtitle('Difference'),substrong.subtitle('Difference amplified 8x'))) This script subtracts one video from the other and shows the differences and the differences amplified by 8x. You can see that there are no differences, even with 8x amplification: Those flat gray expanses at the bottom left and right indicate the two videos are identical.
Then I compared your two PNG files using the same technique.
