How to Automatically Sync Audio Across Comps

By January 29, 2019No Comments

Emanuele Colombo shares an easy way to sync audio automatically across various compositions in After Effects.

Comps and nested comps are a great way to organize and work more smartly in After Effects. When you are working with a large number of compositions, the problem becomes how do you keep audio synchronized across all of your timelines? With a little expression of course. Animator and motion designer Emanuele Colombo demonstrates with this short quick tip – How to automatically sync audio.

The key to the trick is a little expression that you can easily copy and paste to be on your way. The expression is:

[syntax type=”js”]

MasterC = “Name of your main composition here”;
PreC = thisComp.name;

C = comp(MasterC);
L = C.layer(PreC);
Main_T = time + L.startTime;

[/syntax]
