Have you ever wanted to layer or mix different videos together? Or perhaps layer multiple videos, one on top of the other, or add a watermark image? If so, this is called "compositing", and is a super cool, and very useful technique when editing videos. I thought it would be fun, to offer a quick and simple tutorial for new users, and show the basics of multi-track video editing using OpenShot.
Here is the main screen in OpenShot. It contains three different layers (also called "tracks") at the bottom of the screen (labeled 1, 2, and 3). These tracks behave much like layers of paper on your desk: the bottom track is covered up by the track directly above it, and that track is covered up by the one above it, and so on, for as many tracks as you choose to add.
Clips on this track will be on top. Logos and watermarks should be on this layer. The OpenShot logo is on this track in the illustration.
These clips are under the top track, but above the bottom track. The image with circles is on this track in the illustration.
These clips are under all other tracks. The sunset is on this track in the illustration.
