Overview
Tracks a model through a shot and holds it there. The correction workflow is the point: grab a pin on any frame, nudge it, and the solve re-fits around what you stated.
How to
- Wire the plate and the geometry.
- Position the model on the clearest frame using the viewport handles (the Select tool returns the ordinary camera controls).
- Track, then correct where it slips.
Inputs
| Input | What it takes |
|---|---|
| geo | the geometry |
| src | the source image |
| mask | limits the effect to this matte — the engine's universal mask slot, applied for every node that declares it |
| cam | the camera to project through |
