CamTrackAR for iPhone download

Product snapshot

CamTrackAR is an iOS-based mobile virtual production toolkit that captures a single reference point for camera tracking while recording video. It lets you place 3D assets into a virtual scene, remove subjects from backgrounds using professional chroma key tools, and preview VFX setups live as you shoot. Capture, edit, and export projects on the fly to verify shot viability during production.

Main capabilities

Import 3D assets into your scene and position them quickly with simple touch controls.
Remove backgrounds with green or blue screen keying and layer virtual environments for instant pre-visualization.
Export scenes and tracking data in common and high-quality formats for further finishing.
Precisely key individual subjects from their backgrounds using either an automatic tap-selector or a green-screen workflow.
Simultaneously record video and 3D camera tracking data, then add virtual backdrops to check composition in-camera.
Bring generated files into other tools for finishing and compositing.

Capture and camera tracking

CamTrackAR records video and captures 3D tracking information at the same time, providing a synchronized dataset you can use for matchmoving and pre-visualization. A visible green tracking grid assists the app in estimating camera motion, so you can place virtual objects relative to the live action with minimal setup.

Chroma key and compositing

The app includes industry-grade chroma key functionality for both green and blue screens. Use the built-in keying tools to strip backgrounds away or tap to select and isolate an object. Combine keyed subjects with imported virtual backgrounds to build believable previews of your final VFX shots right on set.

Export options and downstream workflows

CamTrackAR lets you export captured projects in high-quality (.hfcs) and flexible (.py) formats. Outputs are designed to be compatible with common post-production tools — you can import CamTrackAR files into apps such as After Effects, Apple Motion, Autodesk (FBX), or open them as plain text for custom pipelines.

Alternative recommendation

For a free option that also supports video capture and tracking data, consider Gorilla Tag Free — it allows simultaneous recording of footage and 3D track information and can be used with imported virtual backgrounds for on-set pre-visualization.
