How to replace Video in a Shot when it was not shot with Green Screen or Locked Down
Hello –
I’m editing a documentary and need to replace some video in shots of TVs that were not shot with green screen or locked down. Ultimately, a job for a master effects person, but I want to use Adobe Premiere (or whichever part of Adobe CS6 is best suited for this), to do a rough replacement.
I’m an Avid & Final Cut editor, just learning Adobe, and will just do these shots there to import into Avid project.
Does any kind soul know the steps I would take to do this? I think it involves creating my own “fake” green screen, and imagine I’d also have to get Adobe to track the video image on the shot I’m replacing.
Any suggestions greatly appreciated.
Thanks so much & happy Friday!

Use garbage mattes to cut out the TV screens. Move or change the mattes with keyframes as necessary. If the cutouts move around significantly, use motion trackers in After Effects to follow the television screens, and then link the replacement images to the tracking data. The following post provides more informaion:

The upcoming ‘Mask Tracker’ in AE should help ease this process.
