If you have footage that was shot at a different frame rate than your sequence setting, you can make it match. Select one or multiple footage items in the Project panel and choose Clip > Modify > Interpret Footage. In the Frame Rate section of the Modify Clip dialog box, enter the frame rate value that matches your sequence; this changes the duration of the interpreted clips accordingly. Revert an interpreted clip to its original speed by checking the first option, which sets the frame rate value determined by the video file.

Many graphics include an alpha channel that reveals whatever is on a background video layer in the sequence. If you want to handle the alpha channel differently, you can do so without opening the source file in Adobe Photoshop CC or Illustrator CC. Select the graphic in the Project panel and choose Clip > Modify > Interpret Footage. In the Alpha Channel section of the Modify Clip dialog box, select the Ignore Alpha Channel option and click OK. This will reveal black pixels instead of the background video. Have fun experimenting with the Invert Alpha Channel option, which reveals the background video layer through the graphic, like a stencil.
