In this one minute tutorial we use the automatic beat detection of BeatEdit for Premiere Pro to create markers at the beats of your music and then import the markers in After Effects.
These markers are very helpful when timing your animations such that they fit nicely to the music.
This is useful, for example, if you want a text to appear word by word in sync with the beat.
