  Making walking people and other objects in motion, invisible in a static scene

  Posted by Jim Bachalo on July 14, 2011 at 2:00 am

  Hi
  Can anyone tell me if there is a way to automate the removal of any objects in motion, in an otherwise static(non panning) scene?

  I was thinking some combination of motion detection and content aware fill, but not sure if this is possible in AE without manually masking out all the moving objects and then manually cloning in the static background data.

  That’s what the ‘Difference Matte’ under ‘Effect > Keying’ is for – you feed it a clip with no motion and a clip with motion of the same static scene and it keys out the difference. It does require some massaging and garbage matting to work properly.

  Thanks for that!

  I think the problem I will have is that I still want to keep some motion in the background but remove other motion (walking pedestrians) in the foreground. WIll need to do some tests but my hunch is that it will require manual rotoscoping as well
