Supported formats
Kapnetix Post reads the common motion-capture interchange formats and, on export, writes back standard editable files that drop straight into your pipeline.
Format support
| Format | Source | Read | Export |
|---|---|---|---|
| FBX | Autodesk (Maya, MotionBuilder) | ✓ | FBX |
| C3D | Marker-cloud standard | ✓ | Keep original |
| BVH | Skeleton / hierarchy | ✓ | Keep original |
| TRC | Marker trajectory (Motive/OpenSim) | ✓ | Keep original |
| TAK | OptiTrack Motive | ✓ (read-only) | FBX |
| VDF | Vicon Shōgun | ✓ (read-only) | FBX |
Format and tags are auto-detected on upload — you don't select the type by hand.
Read-only formats: TAK and VDF
TAK (OptiTrack Motive) and VDF (Vicon Shōgun) are read-only. Kapnetix can load and clean them, but there is no writer for either format, so their clean versions and exports come back as FBX. The upload and export dialogs state this so there's no surprise at the end of a run.
Everything else round-trips in its original format when you choose Keep original on export.
Convert export
Converting between formats on export (for example C3D → BVH) isn't wired yet — it arrives with the convert worker. Until then, use Keep original, or FBX for TAK/VDF. See the FAQ.
Capture systems
Kapnetix Post works with takes from:
- Vicon — optical marker systems (and Shōgun
.vdf). - OptiTrack — optical marker systems (and Motive
.tak). - Markerless — computer-vision / markerless capture.
Frame rate
Takes are handled at 120 fps. Duration, marker count (typically around 53), actor count, and capture system are read from the file and shown on the take's stats panel after diagnosis.
