Advice keying problems with motion actress
on Nov 27, 2012 at 2:05:47 pm

Hello everyone,

Quick question, When doing the keying using keylight 1.2, the result looks fine however the original footage, 1080p 25f has a "dragging effect" dont know how to call it exactly therefore I have pink and red edges around the moving arm of the actress... (see picture attached)

Any advice on how I can solve this issue? Maybe pre compose and work over the arm separately?

Thanks a lot for the help!

You don't say which version of AE you have, but the Feather Masks feature in CS6 can be a real friend here. What you're seeing is motion blur - the video was shot with a slow enough shutter speed that the arm movement is too quick to be captured in focus, hence the blur.

I've had good luck using a combination of the Roto Brush and masks to clean this up. It's tedious, though. Good luck...

CS5 is the version Im working with...

Gonna give it a try to see if by using masks I can get rid of it. Thanks a lot for the reply!

You can still feather your masks, you just don't have the total control of the new Mask Feather feature. It's worth the upgrade just to get that one feature:
