I've recorded 2 songs in the studio and would like to make a video of me playing all the instruments so I can upload it on Youtube. I filmed myself playing each instrument (including singing) from start to finish without any audio recorded, so I now have 4 clips that are in time with the song. My plan is to find a way to line up all 4 tracks to be perfectly in sync with the audio, then I would like to cut and switch between each clip. (eg. switching to the guitar playing clip during the guitar solo) If that makes sense. I thought I'd be able to do it on iMovie, but I can't seem to figure how to do what I'm trying to achieve. Ideally, I would also like to crop each clip a little and add a bit of a tint to them as well. Here's an example of what I'm trying to achieve here: However, what I'm after is much simpler than this example. I don't need any extra cropped video over a video. Could anyone help me out here? Thanks in advance!
