Frequently Asked Questions
Does this replace manual rotoscoping?
For most use cases, yes. One-click masking with automatic tracking replaces frame-by-frame rotoscoping. Handles hair, transparent objects, and motion blur better than traditional roto tools. For hero VFX shots requiring perfect pixel accuracy, you may want to refine edges manually.
How do I select what to mask?
Click any object to auto-detect it, or use the lasso tool for precise selections. The model propagates your selection across all frames from a single keypoint.
What output formats are available?
MP4 with alpha channel or PNG image sequence with transparency. Both are standard compositing inputs for After Effects, Nuke, and Premiere.
Does it work with camera movement?
Yes. The model handles pans, tilts, and handheld motion. The mask stays locked to the subject across the full sequence.
What are the input limits?
Upload up to 1080p MP4 files, up to 300 frames (about 10 seconds at 30fps). We're working on increasing the limit.
How is this different from After Effects RotoBrush?
RotoBrush requires manual refinement on nearly every frame and struggles with complex edges. This tool propagates from a single click and handles fine detail - hair, transparency, motion blur - with less cleanup.
Can I get a clean matte?
Yes. The tool provides both the isolated subject and a clean matte that you can use separately in your compositing workflow.
