I made a video using vids from my digital camera. The clips are 640x480, avi, 30.00300 fps, 1:1, motion jpeg. I was able to take my 20 or so clips, cut them up, lay them out just fine and save it. This was yesterday.
Today I tried to add videos from a friends camera: 640x480, mpg, 30.0 fps, 1:1, mpeg-video.
My video kept going black when i dropped it into the timeline with my other clips. I tried creating a new project, this time square NTSC (the first one was dv pal). I'm getting all kinds of problems now with clips not playing in the timeline, or they play and when I go back to them they dont, or there's just a white shell where the movie should be. This is very frustrating. What to i have to do to merge these two series of videos together? I'm getting black playback now when only one type of video is added.
