Track a subject.
Keep the matte.
Select and refine a subject in the Windows app. Track a shot, export a black-and-white H.264 matte, then use it for blur, grading or compositing in a compatible editor.
Release preparation is underway. Sales and trial downloads are not open.

When a mask needs to move between steps
Frame-by-frame adjustments add up
The more often you redraw a subject boundary, the less time remains for the finishing work.
A mask can get trapped in one step
Processed pixels alone are difficult to reuse in another editor or another finishing pass.
The same subject gets selected again
Instead of defining the target separately for blur, color, and compositing, keep one transferable matte as a source asset.
Make it standalone. Deliver it as a matte.
Select and refine a visible subject
Open a video in the Windows app, select a subject that is clearly visible, refine the selection when needed, track the short shot, and review the result.
Export a reusable black-and-white matte
The output is a black-and-white H.264 matte with no finishing effect baked in, ready to hand off to an editor that supports the format.
Use the GUI or headless CLI
Alongside the GUI, the CLI accepts an input video, seed JSON, and output path for scripted matte generation. AI inference runs on your PC.
See It in Action
Review the generated black-and-white matte and an example of using it in an editor. Check the output on each source clip.
These demos are edited for playback, not processing-time benchmarks. Review and refine tracking for each shot.
Reuse the same matte in finishing
Export the black-and-white matte, then reuse it as the target area for blur, color, or compositing in a supported NLE.
Inspect the matte before finishing
Review tracking as a black-and-white matte before baking in the finishing treatment. For footage where the subject stops being visible, inspect the result and refine it when needed.
A workflow that leaves a reusable asset
Rotomancer is a Windows standalone app, not an effect built into an NLE. Make a black-and-white matte in the GUI or CLI, then hand it off to editing.
| Step | Role / output |
|---|---|
| GUI | Select and refine the subject |
| Headless CLI | Run from seed JSON |
| Export | Black-and-white H.264 matte |
| Supported NLE | Use as a track matte |
The current v1 workflow
Inside Rotomancer
- →Choose a frame where the subject is clear
- →Track the short shot and review the result
- →Export the black-and-white matte
Inside the editor
- →Import into an NLE that supports the exported format
- →Reuse the same matte across finishing steps
- →Review the composite and refine when needed

Rotomancer exports a black-and-white H.264 matte video. Import it into Premiere Pro, DaVinci Resolve, Final Cut Pro, or another NLE that can use the exported format as a track matte, then use it as the target area in finishing.
Version 1 selects, refines, tracks, and exports a visible subject in a short shot. Results vary with the footage, so review the matte before export.
