Use the Interleave tool to interleave the frames of two source clips. You specify how to interleave the two clips in the Spacing field. For example, a spacing value of two mixes two frames of the second source clip after every frame of the first source clip.

To interleave two clips:

1. With Video selected from the A/V Tools box, click Interleave.
2. Set the spacing for the interleave in the Spacing field.
3. Select the source clips.
4. Select the destination for the result clip.

   The result clip appears in the selected destination.
