Hello creative people,
I’ve been thinking of a way to remove a moving subject from his background without rotoscoping.
Knowing that in my case, there isn’t any greenscreen.
More important though, knowing that i’m talking about shots with a static camera.
Is there a way in Adobe After Effects to tell the software :
- This is the shot of the background with the subject
- This is the same shot with the background only. Without the subject
- Pease (yeah I know, I’m polite with my softwares), AE, could you put out the subject from the first shot using the differences between the two shots ?
It seems so easy said this way. So easy that I would be surprise that such a feature doesn’t exist, right ?
PS: When I was a kid, I remember using my webcam with a software that could remove the background from me using this technique
The method was simple : I had to push a button, get away from my background for 5 seconds and then the background was gone once I was back in front of my webcam ! As simply as this.
Yes, you can do this with a difference key... or is is difference matte? I forget. But for best results, the backgrounds have to be identical down to the last pixel. Because that's how it works -- it compares corresponding pixels in the two shots. If there's the least bit of difference, it's opaque.
So no moving the camera, and no auto irises!
