About pt_CropPrecomps

pt_CropPrecomps, authored by Paul Tuersley, is a script for Adobe After Effects that trims nested compositions down to the bounds of their actual pixel content. The result is a set of pre‑comps sized precisely to what they contain, making it easier to animate Photoshop files imported as layered compositions. Users import a Photoshop file as a composition (using the ‘Cropped Layers’ option in CS3/CS4 or the ‘Retain Layer Sizes’ option in CS5 and later), open the main composition, and click the Crop Precomps button. The script can target only selected precomp layers, supports Photoshop vector masks, and handles non‑square pixel aspect ratios. It is compatible with After Effects versions from CS3 through the 2026 release. A demo video is available on the developer’s page.
