I have a question: “I have an audio visualizer and I need to manually change the duration of hundreds of comps to adjust it to the new song. Is there a way to automate it?”.
Go to Window-AEJuice Pack Manager.
Click on the lightning icon – Increase duration.
Enter the desired duration.
The script will go through active composition and its nested compositions recursively and adjust duration (both comps and layers).
You can select a layer to increase only the layer’s duration with its nested precopms.
