I am trying to make a video showing me playing various instruments arranged together in a song. The effect that I want to achieve is exactly like this.
The person in the video is a friend of mine, and he told me he created the video using iMovie. But he was only able to mix two videos at once, so he resorted to mixing two videos, exporting, mixing together with another one and so on.
I already have the various snippets filmed, and I would like to put them together in a collage, but using a software that allows superimposing many videos at once ( at certain points I have eight). What kind of software allows this?
Ideally I would use a Mac, but Linux is also fine (as long as it does not need enormous amounts of resources, since it is an older machine)
