A track matte is an undetectable layer that is utilized to control the haziness of the layer specifically underneath it. Basically, they supplant the alpha channel of the layer they are being connected to.

How about we accept you have 2 layers of footage on top of each other. The top layer will, if its haziness is set to 100% and you have not connected any covers, cloud the layer beneath it altogether.

In any case, you can add a track matte to the top layer to control its haziness. To begin with, you should include another layer specifically top of the layer you need to utilize it as a matte for. This layer can be anything you need: content, shapes, a video or another creation. In the accompanying case I basically included a couple shapes onto my new layer:
