Ever have a piece of footage like a background that you just need to loop forever throughout your video? Here are two ways of easily doing that. One using Interpreting footage and putting in the number of times you want it to loop and the other more flexible method of using time remapping and a simple expression.
METHOD 1: INTERPRET FOOTAGE & SET LOOP NUMBER
1) In the project panel right click the clip you want to loop and select “Interpret Footage” and then “Main”
2) At the bottom of the window that pops up there is a section called Other Options where you can put in the number of times you want to loop the footage. Put in a number would make the clip longer than your composition timeline.
3) Extend your clip in the timeline to however long you want it to be.
METHOD 2: TIME REMAPPING & THE LOOP OUT EXPRESSION
1) Right click your clip in your composition timeline and select “Time” and then “Enable Time Remapping” it will automatically add keyframes to the beginning and end of your clip.
2) Alt/Option click the stopwatch on the time remapping keyframes to open up the area for you write an expression.
3) Type in the expression: loopOut()
4) Extend your clip to however long
The loopOut() expression very simple and doesn’t only work for time remapping but ALL keyframes. It’s one you should memorize as it comes in handy many times. If you ever need to repeat a series of keyframes over and over just add in the loopOut() expression and you’re good to go.
