Comment 4 for bug 1486750

>>>Did you open video in VLC? Look at the scrennshot, the difference is not so big, but exists (openshot on the left, vlc on the right)

NO not before but now yes. And frankly, I see no difference and even in openshot I got none problem.

>>>I've played the video with ffplay (from winff) - the same behavior
ffplay from winff ?
Just type in a console
melt Sample.mov
and
ffplay Sample.mov
and put here the result and tell us what do you have.

Ah ah I understand (at least for me there are two months ago). I was using this ppa for getting the last version of ffmpeg and I have had a lot of problems and not only with openshot with a lot of softwares using it (ffmpeg). IMpossible to do something (imagination, ffdiaporama, ff multi converter.........
I have resolved this issue using the ppa that you 'll find in the faq 1040 update of the 30 june.
You should do that to my mind.
