I think what he wants to do, what will really be good for him is to wear a mask. F3 in the composer.

Another option is to edit this video that you want to put on top, with the measurements you want 1:1, export it like this, and then insert it into this project.

Have you tried the "Crop & Position" plugin instead of the "Crop tool" in the Compositor?  IgorBeg is the expert on usage.

I have two video tracks; one is overlayed on the other. I'm using projector automation to put the overlay video in the corner of the underlying video. I would like to crop the overlay video so it only shows the section I'm interested in. The overlayed video is a 1:1 image in the middle of a 16:9 video, and I just want to show the 1:1 bit. I can't figure out how to do this.

- I thought I would be able to use the camera automation to scale the image after I had placed the projector, but while this works, it happens before any track plugins are rendered, and as one of these is rotation I always end up with a rotated rectangle on the screen. (With black borders.)

- using the crop plugin adds more black borders.

- I tried a mask, but I haven't found out how to invert the mask (i.e. I draw the area I want displayed so that everything else is cropped); plus cropped areas show up as black.

- I simply can't get my head around the crop tool.

The best I've come up with is to add a scale plugin to the track to resize it up a bit, so that the black wedges caused by the rotate plugin aren't visible; then adjusting the camera to zoom in on the are I'm interested in; but I haven't found a way to change the shape of the projector yet. It's always a 16:9 rectangle, but the area I want to show isn't that shape.

What's the right way to do this? Ideally what I would like is the ability to draw a path on an object on the screen and say 'clip this object to this path'. Does anything like that exist?
