Fade out sound on a trimmed composition
on Feb 5, 2020 at 12:07:18 pm

I have a file in which I programmatically change the footage via a plugin.
I have a sound layer that is trimmed (adapts) to the length of the video.
Is it possible to fade out somehow the volume of the video at the end of the trimmed composition?

Hey Otto, for audio layer/composition, add effect Audio > Stereo Mixer and apply expression to left & right levels, which:

1. Gets comp/layers duration based on your setup;
2. Uses linear interpolation linear() to fade audio from 100 to 0.

In order to help you further, please share screenshot of your comp, where layer is updated via plugin.
