If your clip is short, we're going to do a little loop trick with expressions to make it loop over and over.

1. Trim your layer if you need to by changing the In and Out points. See 'Trimming layer footage' in the Adobe After Effects Help for more information.

2. Apply Time Remap to the layer. Layer > Enable Time Remapping.

3. Tap the I key (that's I as in India). That will bring you to the in point of your clip. Set a keyframe for Time Remap by clicking the stopwatch.

4. Tap the O key (that's the letter O, as in orange). That brings you to the outpoint of your clip. Add a keyframe here.

5. There may be other keyframes in set for Time Remap. You can delete them.

6. Add an expression to Time Remap. Select Time Remap in the timeline and go to Animation > Add Expression.

7. Use the pull down menu for expressions by clicking the box with the right arrow. Select Property > loopOutDuration(type = "cycle", duration = 0) or just type:

loopOutDuration(type = "cycle", duration = 0)

8. You may need to drag the footage layer out to fill the timeline. You can go to the last frame of your animation, select your layer and hit option + ] (right bracket) on the Mac or alt + ] (right bracket) on Windows. This will force your time remapped footage fill the timeline.
