Using a mask to create an image that's distortable
Essentially I'm trying to create a mask that captures the image it encircles and allows me to distort the image. For example, if I have a picture of a person and draw a circle mask around the person's head, when I distort the mask it distorts (e.g. stretch/skew/bend) the person's head and not just the shape of the mask. I'm trying to create my own version of this video but using Motion instead of AfterEffects and Mocha.
If you watch the tutorial it's the AfterEffects "precompose" function that I'm trying to mimic. And I don't think creating a new Group in motion is the ticket because I can only distort the image by adjusting the edge of the canvas vs. the edge of the mask.

Thanks for any and all help! It's been a couple of frustrating days...
