I'm creative a music video for a college project and came across this effect I would really like to use.I saw this Batman video on collegehumor and saw this throbbing background effect when Batman looks at Scarecrow.





@ 0.46 and various other parts of the sketch. I understand it was probably used with green screen but how would the throbbing background effect be achieved?

All answers are helpful, thank you

It is green screen with a background plate. You'll find various scripts and utilities that can keyframe a layers attributes based on audio if you'd like to automate the motion.

Beyond that, if you don't have a greenscreen and a plate, you would need to take a frame, paint out your actor for a clean plate, and then place it under a rotoscoped version of your footage.

Specifically, once you have a separate background layer, you would animate the scale (or one of the Distort effects) and use one or more blur effects to get the result that I saw.

Johnny

As Todd said Animating the scale parameter and using a blur effect could create the desired look.

Check the Example:

Instead of any blur effect, I just used the Native Motion Blur of AE. Though you can use a blur effect to enhance the effect.
