Sound Familiar?

Hours of Manual Roto

Hand-rotoscoping a moving subject? Hours of frame-by-frame keyframes for a single shot.

Trackers Drop the Subject

Auto-trackers lose the mask the moment the subject moves fast, leaves the frame, or passes behind something.

Locked to One Effect

Most tools bake in blur or pixelate. You want the mask itself — to drive whatever effect the shot needs.

Built for the Hard Shots

Holds Through Motion

Click once. The mask tracks fast movement, frame in/out, and occlusion — and re-locks onto the same subject even after they're fully hidden and reappear.

One Mask, Any Effect

Rotomancer generates the matte. Drive mosaic, blur, replace, grade — anything — from the same mask.

Local & Batch

Runs entirely on your machine and processes long clips in batches. No uploads, no per-minute fees.

See It in Action

Hours of frame-by-frame rotoscoping, replaced by one click.

One mask, any effect

Generate the mask once — then drive mosaic, blur, replace, or any effect from the same matte. The mask is the product; the effect is yours.

Recovers from full occlusion

The mask tracks fast motion, and even when the subject is fully hidden — behind an object or another person — it re-locks onto the same subject the moment they reappear. Just the AI mask — no effects, no tricks.

What Your Time Is Worth

Not as hard as Mocha. Not as pricey as Topaz. Just click.

MethodTime / Cost

Business

For Teams & Studios — Business Use & Custom Inquiry

For studios processing dozens to hundreds of clips a month, we offer a business track separate from the individual license.

  • High-volume: 100+ clips/month
  • Review-standard assistance for FANZA/DLsite (compliance not guaranteed)
  • Hard-case tracking: fast motion, occlusion, unusual objects

Manual rotoscoping runs 2-4 hours per shot; automation compresses most of it.
