I have wanted this feature for about 15 years. You know the feeling: a Silhouette roto project with hundreds of layers, and you need to collapse all the main layers to find something in the Object List. Now you can. Assign it to a keyboard shortcut and boom.

Because the Python API has no direct way to do this, I had to dig into the Qt/PySide UI to find the correct panel and trigger the layer-expansion action.

Yes! I also worked on Season 2 of Avatar: The Last Airbender. As a contractor for Accenture Song VFX, I worked from May 2024 to April 2026 on 74 shots: 28 matchmove shots, three paint shots, and 43 roto shots. The VFX breakdown below includes a few of my shots.

Use this script to optimise frame sequences before sending the smallest necessary frame area to ComfyUI, VitMatte, or another GPU-memory-hungry processing or compositing step. It works with RotoShapes, Crop, and CurveTool. Use the offset parameter to enlarge or reduce the bounding box. Python Script is here on Github
