Mask Prompter Features

Mask Prompter

Simple workflow

The masking workflow is super simple. Specify points and rectangles on/around the object. Mask Prompter will create a mask from your prompt. This allows for fine-grained selection, refinement, and easy tracking.



We applied some custom extensions to the underlying AI – therefore you’ll get interactive prompting. Note: The performance will be dependent on your hardware.


Mask Prompter

Stable on video!

It’s very easy to get consistent results on video. The river mask on the right was created with a single point placed on the river!


Multiple output modes

Output your masks as an overlay for visualization, as a black-white matte, or as content witha transparent channel. This allows for versatile integration in your workflow and interplay with AEs inbuilt effects.
