|Summary||0002496: Abnormal fps and its effect on "blue screen" effect|
|Description||I use a Sony HDR-HC9 MiniDV High Definition Handycam Camcorder (mpeg2), and after acquisition by using kdenlive, some (but not all) of the video m2t files have abnormal fps (according to ffmpeg -i): e.g. 30.65, 25.68, etc... instead of 25.|
I never noticed it before and I think this has no impact when no effect is used in the montage.
Recently I used the blue screen effect, and when I use it on one of these clips, I get a very large desynchronization of sound and video, and kdenlive seems to loose montage points.
|Steps To Reproduce||just add blue screen effect on one of these clips with abnormal fps.|
|Additional Information||So far I resolved the question by doing this:|
ffmpeg -i Corse001.m2t -vcodec copy -acodec copy Corse1.m2t
the resulting file has a correct 25 fps, and the blue screen effect problem disappears...
I don't know if the problem is coming from the camcorder of from video acquisition program.
