Starting at 0:10 it includes a beautiful mask. Can someone point me to a tutorial that tells me how to use the second half of the as a mask on the first half, so I can let another layer show through behind the laptop?
Import the first 9 seconds to V1
Import the latter 9 seconds to V2
Apply some mystery command to V2 to make it a mask layer...
-Add the track matte key effect to the footage.
-Choose the video track where the matte is from the track matte key settings.
-Set the correct composite setting for the matte. If it has alpha use matte alpha. If it's a black and white matte then use matte luma.
