Having alot of problem with the timeline on points where clips are joined for transitions, have clips from three cameras hmc151, GH1 and GH2 and have the GH2 clip as the main clip. My problem is that on the points where i've added the HMC151 clip or the GH1 clip, the clips seems to "vibrate" or hang, jump or repeat some earlier frame, i don't know what is causing this since i've been joining clips in FCP and never seen this happening before. All help appriciated.
