matte size doesn’t match original image from DVCPRO HD
Thanks in advance for helping me with this one.
I shot some video (720p/60) of a sunflower with a blownout background sky, thinking to myself that I’ll use a luma key to replace it with a better sky.
So I do that and get those nasty jaggies on the edges of the flower. No problem, I’ll do that lightwrap thang, but when I do it, the new image mask doesn’t match the size of the original image.
Here are the images I’m working with:

…and what it looks like in the Motion Layers tab.

Help!

Make your comp size 1280X720 square pixels. The DVCPro HD footage will be automatically scaled to fit, and your jaggies will magically disappear. I had the same problem in both Motion & Shake, and making the comps full 1280X720 with squar pixels solved it in both programs.
