Did you ever work on an animation that involved something called MUSIC? Its this by-product that comes out of your speakers while the video is playing.

If you treat music in your videos as first-class citizens, beat assistant is a tool for you. It automatically detects the beats per minute of your music and allows you to do lots of things with it.

  • set layer markers according to the beat
  • generate keyframes and animate to the beat
  • stagger layers according to the beat

Easy import to Premiere Pro Beat Assistant with Premiere Pro
The composition markers can easily be imported to Premiere Pro, as Eran Stern shows in his tutorial about Beat Assistant with Premiere Pro.

No expressions
You think animation to the music involves some weird expressions magic to tie your animation to audio keyframes? No, with beat assistant, you do it the mamoworld way: Animate all properties directly using intuitive interfaces.

Beat Detection is achieved with the popular SoundTouch Audio Processing Library. While .wav files are supported natively, to work with .mp3 and .aif files, you need to install the separate tool LAME.

Where is the difference to BeatEdit for Premiere Pro?

BeatEdit for Premiere Pro and Beat Assistant for After Effects are very different.

BeatEdit for Premiere Pro

  • has a way more robust and accurate beat detection engine. In contrast to the AE tool, it does not only predict the beats per minute, but the actual position of every single beat (and even other rhythmically relevant points).
  • has a very powerful and intuitive interface to visualize and select individual beats

Beat Assistant for After Effects

  • is compatible with all After Effects versions since CS4, while BeatEdit for Premiere is only compatible with CC 2014 and CC 2015
  • can also generate keyframes and stagger layers

Hence, if you use an old version of After Effects or if it is very important for you to generate keyframes or stagger layers, Beat Assistant for After Effects might be your best choice. But usually, BeatEdit for Premiere Pro will be the much better, more robust, accurate and flexible solution.

  • Interface to generate markers
  • interface to generate keyframes
  • Interface to stagger layers
