I am trying to sync up the lens flare video effect to a drum loop at the start of my movie. Desired result; simulated camera bulbs going off in sync with the beat of the drum track. Is there a better tool or process in CS5 that would be more effective and time saving than trying to manually animate the flare blasts with the beat?
I can't think of any.
After Effects is your helper here, I use the 3rd party plugin from Redgiant Software Trapcode Sound Keys 1.2. As they say you can "create mesmerizing, complex animations by using the same audio track to drive several types of animation, selecting different audio frequencies for each effect"
There is also deep support within AE (read Todd's message above) and I have read that also Boris FX has support for audio synch.
