Chroma - Why are there wavy lines?

Jun 23, 2011 10:11 AM

I'm using a green screen behind an actor among some crates.

I'm using Adobe Premiere 5.0's Chroma Keying effect to drop different background images behind the actor.

 

The problem?

After applying the Chroma effect, if you look at different crates and at parts of the actor, it looks like the border lines are moving in quick, small waves. Although the waves are small, this is enough to be very distracting.

This doesn't just occur at the borders touching the green screen, this includes the actor's eyes, mouth, and wood lines within the crate. There are absolutely no green on set except on the green screen.

 

In viewing the video clip without the Chroma effect (but using Premiere Pro), the waves disappear. Everything is normal. Same thing when you view the raw footage.

 

How do I correct this problem?

    This question pertains to Premiere Pro, not OnLocation, which is the current forum. If you haven't done so already, please repost on the PPRO boards.
