Hi I use KDEnlive under Ubuntu and have a problem with speeding up a clip that I cutted out of a another clip.
When I apply the effect the videosequence shrinks and the still images in the project monitor seem to be fine.
But if I playback the clip or render it, it plays the sequence as normal (and therefore not the whole sequnce but just the beginning).
Can anybody help me please?

Has realy nobody else this problem?
