Hi, I’m making a video installation in which I am hooking a real life push button up to a patch that will allow the viewer to cycle through 4 channels of simultaneously playing video. (Meaning I would not like to dispoad, read and start over on the next clip in the same LCD, but rather cycle through with each button press as they all play at once. Think of a surveillance monitor.)
Is there a way to have multiple video files play on one iMovie screen at the same time?
I think you should try Jitter objects, rather than imovie.
In the Jitter tutorials you should be able to find a good starting point for playing videos.
Once you have your four videos playing, [counter 1 4 ] and [switch 4] will help you routing the video streams.
