after effects wiggle expression in opacity

The one placed in # Main is your guide composition. This assumes your synchronized composition is not time-remapped inside the parent ( # Main) composition. This expression was written by the great Zack Lovatt

Now replace the parentComp variable if your composition is named differently. Linear(time, fullStartTime, fullEndTime, fullStartTime+compStartTimeInParent-audioStartTimeInParent, fullEndTime+compStartTimeInParent-audioStartTimeInParent) parentComp = comp('# Main') ĬompStartTimeInParent = parentComp.layer(thisComp.name).startTime ĪudioStartTimeInParent = parentComp.layer(thisLayer.name).startTime įullEndTime = thisLayer.outPoint+thisLayer.startTime For our example we’ll use # Main > Voice over.Īssuming that your main composition is called # Main (see A composition naming system for After Effects for why I think it should), you can just time-remap the composition you want synchronized and add this expression to the time-remap property.

Whatever will work since we’re using time-remapping. It might be a composition containing your voice-over. In your main composition, place the composition you want synced. Inside of it are many compositions and each one is a scene. Let’s say you have your main composition, which contains your animation. So if you happen to know where it comes from, please let me know in the comments and I will gladly give credit where its due. After some REsearch I was not able to find it. Here’s a solution that I’ve been using for a couple of years that works very well.ĭisclaimer first, I know I found this expression somewhere at some point and saved it as an animation preset, but I have no idea where I found it. As soon as you move things around you have to manually resynchronize everything. Animating to audio is an important part of working inside of After Effects.
