Auto Crop 3.1.1 for Mac
Mac VideoAuto Crop 3.1.1 for Mac is a small but very useful Adobe After Effects tool from BatchFrame, sold on the aescripts marketplace as Auto Crop 3. With one click it shrinks a composition down to the exact size of its visible content, removing empty borders based on the alpha channel of every layer in the comp.
Motion designers use it to tidy pre-comps, prepare exports at the true content size and stop renders wasting time on blank space. You can crop at the current frame, or let it analyse the whole timeline so animated content is never clipped. Auto Crop is a low-cost paid plug-in, listed at around $9.99, and it requires Adobe After Effects — it is not a standalone Mac app. A limited free trial is available on the official page.
Key Features
- One-click cropping of a composition to the size of its actual content
- Pixel-perfect results based on the alpha channel of every layer
- Crop at the current frame or analyse the full timeline so animation is not cut off
- Rebuilt as a fast native After Effects plug-in, with a dockable panel
- Keeps layer positions intact and can be triggered from other scripts and KBar
How to Download
- Download from the official site
- Sign in to aescripts, try the trial or buy a licence, then download the Mac plug-in files from your account.
- Install with the aescripts + aeplugins manager app, restart After Effects and run Auto Crop from the menu or panel.
Is Auto Crop free?
No. It is an inexpensive paid plug-in. The official trial works like the full version but is limited to 10 crops per day for 7 days, which is enough to test it properly.
Does Auto Crop work outside After Effects?
No. Auto Crop is an After Effects plug-in and needs a supported version of Adobe After Effects on your Mac. It does not crop video files on its own.
