[Kdenlive-devel] [Mlt-devel] Framerate Issue on MTS files ?

[Marco Gittler]

Hi

i found the piece, that caused the render in double frame rate of the video.
it is setting: 
skip_frame:bidir (which is an ffmpeg option)
is this still needed to be set in the .kdenlive file or was this only needed in earlier versions of ffmpeg ?

regards marco
