The Panasonic GH2 (set to pal) has had two 1080 recording modes: 24p and 50i. I have never used the 50i mode but filmed in 24p which kdenlive was able to handle natively.
Some time ago Panasonic released a firmware update that enabled a 25p mode and this is the mostly preferred framerate, so I do always use it.
Now the problem is, that the 25p Progressive material comes in a 50i wrapper, and kdenlive is unable to handle the files. Pulling the files into either a 25p or 50p timeline shows that kdenlive can not play back the clips at all. Only heavy stuttering and short interface freezes on starting/stopping. Forcing the clips framerate to 25 in the clip properties makes the video play smoothly, but there is no scrubbing possible and starting playback on any timeline position makes the clip play from its beginning. Having two or more overlapping clips in timeline leads to image freezing and strange jumping while playback.
I am not really sure if that is an ffmpeg related issue because Blender play the clips smoothly when the project framerate is set to 50. (Although audio is too short) So I do not even know where to post a bug report ;)
VDPAU is enabled on my system, Kdenlive build with build script. So FFMPEG, MLT and KDENLIVE are most recent versions.
Has someone made the same experience or has some tips?
Here is a short panning clip if you want to try:
Thank you ;)
