Demo Video


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 and composition 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 is possible for the composition markers, 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.

Should I use Beat Assistant for AE or BeatEdit for Premiere Pro?

We have a similar product called BeatEdit for Premiere Pro which will often be the better choice for you.

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

If you use an old version of After Effects (the Premiere tool is only compatible with CC2014 or newer) 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.

Works Beat Assitant with Cs3?

Hi Marvin, sorry for the late reply. No, Beat Assistant does not work with CS3. You need CS4 or newer to use it.

beat assistant works with premiere pro cc version 7?

Hi Dave,

Beat Assistant itself only works with After Effects. But you can use the method shown in this tutorial to cut and paste the Beat Assistant markers from After Effects to Premiere:

This also works with any Premiere CC version.


Hi there,

I'm trying beat assistant for the first time on a wav file and keep on getting the same error message (unable to open de file "..." for reading). I tried MP3 with the same result. How can I fix this problem? I'm using After Effects 2014 release.


Hi Carlos,
is your footage located on a network drive or has permissions such that it is not readable for your current user?

If so, does it change if you move the footage to the same drive where your AE is installed?

If this doesn't help, could you please open a support ticked here:
attach a screen-shot of the exact error message and describe what steps exactly you do before the error occurs?
The more details I have, the faster I will be able to help.


Have just purchased Beat assistant - however, when I copy markers or export the sequence into Premiere Pro - I am ONLY getting 1 minute of markers.

Product was purchased and installed using the key provided.

Hi Paul,
note that Beat Assistant only generates markers in the workarea.
Probably you have set your workarea to 1 minute?


The color selector swatch does not open a color pallet when I click on it. I can type numbers in the value boxes and it changes the color, but it would be a lot easier to just open the pallet and select manually.

Hi Mark,
thank you for pointing me to this bug!
I just published a new version (1.53) in which the color selector should be clickable again.


Beat Assistant for AE looks great! Is it compatible with cc 2017?

Yes, it is fully compatible with CC 2017.

The tutorial on how to copy/paste the markers from AE to premiere is not available at the address you specified
Can you please fix this or even better to let us know how to do this technique here in the comment section? Thank you very much

Ok, i figured it out. You copy paste it as long as its a comp, the markers will be transferred. If its not a comp, the markers will not get transferred.

Thank you for the feedback. In deed it looks like the tutorial has been deleted. I will ask Eran Stern why it is deleted and whether it is still accessible somewhere. Alternatively, our tool Beat Edit for Premiere Pro has a much better beat detector and is prefect to create beat markers directly in Premiere Pro:
