Setting up frames and fields for DDR-based footage

When working with DDR-based footage in After Effects, make sure that your Composition Settings, Render Settings, and the Interpret Footage dialog boxes for the footage files are all set to the fps used by your DDR. If the frame rate in the Interpret Footage dialog box is 29.97 and the Composition Settings frame rate is 30 fps, the footage will appear with duplicate frames.

It is also important to separate fields when importing DDR-based footage. Make sure that the field settings in the Interpret Footage and Render Settings dialog boxes are the same; otherwise, the footage will preview and render with the wrong field order, causing the footage to play back with a jerky appearance. (See Using interlaced video in After Effects.)

For information on using your specific DDR with After Effects, refer to your DDR manufacturer's documentation.
