Hi zdrum & welcome to the forums!
It's not possible to have two movie clips playing on 2 "tracks" simultaneously in iMovie 08. Is that what you mean by multiple frames?
If you want to have more than one movie layer (or track) then I'd recommend looking at Final Cut Express or Pro.
Hope that helps,
This sounds like what I wish to do, Basically as an example I would like to have one clip showing someone's feet whilst on another clip, showing the hands on the same screen. I have seen DVD's where multiple frames are simultaneously shown. Hope this makes sense?
I understand you! The reason I was confused is due to the word "Frame". I was thinking of number of frames of video that make one second...
Unfortunately, it's not possible to have multiple tracks or layers (or clips) of video in iMovie 08.
Final Cut Express can do this easily.
