Generating an outline for masked/keyed objects?

Badass, Mark. Really Badass. I don’t think I’ve ever even used the min/max filter before.
This has given me a few ideas. Can’t wait to try them out.

The outline can be a little chunky so try blurring it – I tried adding a levels filter after blurring to tighten it back up but was surprised that it had no effect.

Hmm. I wonder if that’s because of the channel swap filter?

Hi Mark,
I’ve only just seen this, so many belated thanks! You’re a star!

Amazing video Mark, although it didn’t work for me. The Min/Max filter does not seem to affect the size of the alpha’d image… could this be because I am using a still image with a number of masks instead of an image which has transparency inherent in itself?
Perhaps I should mask out the image in Photoshop and then import it into motion?

Shouldn’t be the issue – really can’t tell without seeing the project

well that did solve the problem… I imported the original photo into Photoshop and selected the person in the photo using the wand and the eraser to get the desired and appropriate transparency, then imported the .psd into Motion and the Min/Max feature in conjunction with Channel Swap did work as you describe.
on the image with the masks, I removed the masks and applied the min/max filter to see what would happen, and what it appeared to do was enlarge (using maximum) or “crunch” (minimum) the pixels of the image, rather than enlarging image size itself
sorry, I’m very new at this and totally lack the understanding or the vocabulary to explain myself or the problem accurately… but got there in the end.

Yes you need the transparency to have an edge to work with. Glad you got it figured out.
