Chroma Key & Multicamera

I can't figure out the best way to do this, I have a three camera shoot - with a green screen. I would like to use a different background image with each angle.

Up until now - I have been rendering each shot seperately first before putting it in multicamera mode. So in the end I'm rendering the video twice which is a bit time consuming and loses some quality.

Thanks in advance!

Compositing IS time consuming and usually DOES require multiple renders.
Your methodology sounds to be exact... it's your patience &/or equipment that needs a bit of tweeking.

I would:

- Edit the 3 Angles separately - ChromaKeying my Backgrounds.
- Bring in the 3 Angles with BackGrounds and Edit my final.

or

- MultiCam Edit my piece on GreenScreen.
- Flatten this to 1 Video track.
- Insert appropriate BackGround under the cuts and ChromaKey.

I wouldn't worry about losing quality during my intermediate renders as I would be rendering to the same format or better. (Mathematically you may lose a bit of quality but Aesthetically no one will notice.)

Thanks! I was really hoping that there was some way of linking background and video as one camera track.

Nested projects (1 for your first and 1 for the second track) ?

It works with multicam.
