  [AE extend script] how to add expression to hidden ‘audio levels’ property

  Posted by Emid Rianta on October 20, 2020 at 5:49 pm

  i made script to create a new comp and add expression to audio levels. but as you know in the timeline, new comp has no audio so the ‘audio levels’ property is hidden.
  any idea/trick how to solve this?

  You can add a “Audio -> Tone” Effect to the comp-layer.
  This will force the layer to generate audio and reveal the audio levels property.

  After you’ve assigned your expression to the audio levels, it is safe to remove the Tone effect.

  The audio levels property will be hidden again, but the expression will remain in place for when the pre-composition gets sound again in the future.

  Alternatively, just keep the tone effect but set its Level parameter to 0%
