Removing a background using a picture
on Jan 5, 2014 at 2:45:59 pm

Hi!

I recently came across a problem. I have my friend in front of a bit complex background, but I have the picture of the exact same background taken from the same spot as the video itself. My question is how to remove the background from the video, using the picture? I tried rotobrush, but it's quite timeconsuming.
I'm sorry if my explanation wasn't clear, I upload 2 pictures (one from the video, and the background itself) to help.

Snapshot from the video:

The background:

You can start with the Difference Matte effect. It may require some cleanup, but it'll get you started.
