Aescripts: Mask Prompter V1.0.0 For After Effect...

While this article focuses on AEScripts Mask Prompter v1.0.0 for After Effects, the roadmap is exciting. Version 1.0.0 lays the foundation: local processing, Nvidia acceleration, and text-to-mask. Future updates promise:

Upon applying the effect, v1.0.0 typically attempts an automatic "Instance Detection" pass, identifying distinct objects in the frame. The user can then click on the desired object to generate a base mask.

At its core, Mask Prompter is a machine-learning-powered generative masking tool. Unlike traditional rotoscoping, where you manually draw Bezier paths or paint strokes frame-by-frame, Mask Prompter uses a multi-modal approach. AEScripts Mask Prompter v1.0.0 for After Effect...

The "v1.0.0" designation is significant. It marks the stable, public release of a tool that is not a beta. It promises:

It does not export to a proprietary "AI layer." It generates standard, editable Mask 1, Mask 2, etc., which means you retain full keyframe control after the AI finishes its job. While this article focuses on AEScripts Mask Prompter v1

In the simplest terms, AEScripts Mask Prompter v1.0.0 for After Effects is a generative AI rotoscoping tool. You type a prompt, it creates a mask.

Forget painting strokes of green and red. Forget tracking point clouds. With v1.0.0, you open the extension panel, type a sentence like "the red car" or "the guitarist's left hand" or "everything except the sky," and within seconds, Mask Prompter analyzes the frame and generates a precise, trackable mask around that object. It does not export to a proprietary "AI layer

It leverages a local AI model (no cloud upload, no privacy concerns) that understands semantics—meaning it knows the difference between a jacket and a shadow on that jacket.
