# Aja Studio Mocap Cleanup And Retarget

## Scope

V2 studio shoots continue to use Vicon / OptiTrack as physical capture hardware.
The software path for cleanup and V2-skeleton retarget is Aja:

- `@aja/motion-pipeline-sdk` for ingest, marker-solve import, gap fill, jitter
  cleanup, contact cleanup, and root-motion normalization.
- `@aja/neural-retargeting` for V2 fighter-skeleton retarget and retarget
  quality evidence.

## Contract

Before `shoot_ingest`, the capture session must pass
`@v2/aja-consent-nil-ledger`: every performer has active
`@aja/consent-management` consent, the Themis `@themis/likeness` license ID is
linked through `consentChainRefs[]`, and `rightsManifestSha256` matches
`V2/legal/rights-manifest.json`. Any revocation blocks future Aja processing and
Bellona cook for dependent clips.

`@v2/aja-studio-mocap-pipeline` emits a content-build-only plan with stages:

- `shoot_ingest`
- `marker_solve_import`
- `cleanup_gap_fill`
- `contact_root_cleanup`
- `neural_retarget_v2_skeleton`
- `retarget_quality_gate`

The hardware policy records Vicon / OptiTrack as `recording-only` and sets
`motionBuilderMayaFallbackAllowed: false` for the default production path. Maya
and MotionBuilder remain manual review tools after Aja output, not the primary
cleanup or retarget owner.

The accepted retargeted clip then flows through
`@v2/aja-bellona-livelink-export`, where `@bellona/mocap` performs 60 Hz
frame-snap export and `@bellona/unreal` receives the editor-only Live Link
handoff for cooked AnimSequence import. Runtime Live Link plugins remain
disabled for V2.
