Hello Coachmann,
I know the problem, when I import the film from my camera it runs smoothly, but for editing the movie I use another program because, there are more possibilities for editing. But there the film runs jerkilly. I have to look where the problem lies, the camera made the film with 30 fps, The program for importing the film did save the film with 30fps. The Editing software seems to run with 25fps, but when I open the film it asked me if I would like to change the settings to the settings of the film, so there it should also run with 30 fps.
