PremierePro

Set how an alpha channel is interpreted

  1. Select a clip in the Project panel.
  2. Choose File > Interpret Footage or right‑click (Windows) or Control-click (Mac OS) and choose Interpret Footage from the context menu.
  3. In the Interpret Footage dialog box, select any of the following Alpha Channel options and click OK:
    Ignore Alpha Channel
    Ignores the alpha channel in the clip.

    Invert Alpha Channel
    Reverses the light and dark areas of the alpha channel. This swaps the transparent and opaque areas.
    If you have difficulty identifying which parts of a clip are transparent, choose Alpha from the Program view menu in the Program Monitor. Another way to see areas of transparency is to add a bright solid color matte on a track below the image you are keying.
