Unlike standalone AI applications, Mask Prompter is native to the After Effects environment. It functions as an effect plugin, directly generating mask data onto the selected layer. This eliminates the need for round-tripping between external software (like Runway or Adobe Photoshop) and the timeline.
This is the headline feature. You type a descriptive phrase into the prompt box.
Score: 8.7/10
AEScripts Mask Prompter v1.0.0 is not a magic wand that solves all masking problems, but it is arguably the most significant UI/UX leap in rotoscoping since the Roto Brush’s debut in CS5.
By allowing you to interact via natural language, the tool democratizes a historically technical skill. A graphic designer who fears the pen tool can now extract a logo from a video by typing "circle with a star inside."
If your daily work involves isolating objects in After Effects, the time saved on the first project alone will likely cover the cost of the plugin. It is stable, surprisingly accurate for v1.0, and integrates flawlessly into the standard AE pipeline.

Mask Prompter v1.0.0 is an AI-powered plugin for After Effects designed to automate the rotoscoping process. It allows users to create high-quality masks and mattes by simply "prompting" the AI using points, boxes, or even text, significantly reducing the time required for manual masking. Key Features of v1.0.0 AI-Driven Rotoscoping
: Automates subject isolation, serving as a faster alternative to the standard Roto Brush tool. Multiple Prompts Support : Users can guide the AI using:
: Selecting specific parts of an object to include or exclude.
: Drawing a simple bounding box around the subject to define the selection area. Real-Time Feedback
: Provides immediate visual overlays of the mask, allowing for quick adjustments. Edge Refinement : Includes post-processing options like Edge Enhancement (medium or high) to smooth mask borders with a slight blur. Flexible Output
: Supports outputting results directly onto a transparent background for immediate compositing. Performance & Modes Fast Preview Mode
: Optimized for lower-end machines to provide quicker interaction while editing. High-Quality Mode Unlike standalone AI applications, Mask Prompter is native
: Delivers more precise results for final renders but may slow down the live preview. Hardware Acceleration
: Utilizes GPU acceleration (Nvidia) to speed up video analysis and matte generation. Common Use Cases Text Behind Subjects
: Quickly isolate a subject and place text or graphics between the subject and the background. Background Removal
: Effortlessly remove backgrounds from complex footage with fast-moving subjects. Matte Generation
: Create clean alpha channels for color grading or applying effects to specific areas of a clip.

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 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.
If your footage has color grading, noise, or grain, the AI might get confused. Pre-compose the clip, apply "Remove Grain," then run Mask Prompter. The AI sees flat, clean edges better.
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.
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.
