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? -- ┌─── http://www.cowlark.com ─── │ "I have always wished for my computer to be as easy to use as my │ telephone; my wish has come true because I can no longer figure out │ how to use my telephone." --- Bjarne Stroustrup
