  • Using straight black and white video footage for transitions in AE

    Hi Everyone,

    I know this probably really simple stuff, but I just can’t seem to figure it out. I have some pre-made Black and white movies to be used for transitions in after effects (stuff like black dripping over a white frame until it completely covers it). My question is, how do I bring this footage into after effects and use it as a transition between two images (where the white area becomes the background and the black defines the end. Any help would be much appreciated.

    First, you import your footage into after effects through File>Import>file… (Ctrl+i).

    Then drag the footage into the timeline and above the footage you want the transition to work on.

    Check the trackmatte box in the modes section in the timeline for your black & white footage. Then, for the footage layer under your trackmatte, select the trackmatte dropdown box and choose lumamatte or inverted lumamatte depending on what you want and how you set up your layers.

    That should be what you’re looking for.

    peace,
    Michael
