Auto Crop allows you to instantly crop a composition down to the size of its contents. Crop a composition at the current frame or analyze an entire composition’s content and crop without cutting off any animation
Auto Crop2 now even allows you to crop the current comp without it needing to be a pre-comp. In the newest version, Auto Crop has been rebuilt from the ground up as a native plug-in to provide new features and better results.
Pixel Perfect Accuracy
Auto Crop produces pixel-perfect crops based on the alpha channel of every layer within a composition. If even a single pixel is partially visible, Auto Crop will see it and include it in the crop dimensions.
