Is ZEISS CinCraft Scenario the same as Ncam Reality?

CinCraft Scenario is the ZEISS product built on the Ncam technology. ZEISS acquired Ncam Technologies on 18 July 2023 and launched Scenario in the CinCraft ecosystem later that summer, with CamBar, Origin and Link hardware and the Scenario, Wrangler and Export software. When people ask about an "Ncam alternative" today, Scenario is the current form of that system.

Does RedSpy need markers?

Yes. RedSpy is a marker-based optical tracking system using retroreflective markers on the ceiling, walls or floor, and patented pierced markers on LED walls. The markers give it an absolute reference, no drift and recovery from tracking loss in under 0.2 s. The placement is done once per studio and the map is reused indefinitely.

Which system works outdoors?

Both. RedSpy tracks floor markers in daylight at long distances and is used on live sports and outdoor broadcasts. CinCraft Scenario tracks natural features outdoors and is aimed at set extensions on location. The difference is what you carry: markers for RedSpy, the scene itself for Scenario.

Can I keep my ZEISS lens data workflow with RedSpy?

RedSpy reads lens position through internal serial encoders on Canon and Fujinon lenses or through external zoom and focus encoders, with absolute ranges that do not need a reset at power-on. ZEISS eXtended Data is specific to the CinCraft ecosystem; with RedSpy the lens is calibrated once in the RedSpy workflow and the calibration is kept.

Which is better for LED volumes?

Both work on LED volumes. RedSpy uses its patented pierced markers on the wall, so the wall content does not affect tracking. CinCraft Scenario uses digital markers displayed on the LED wall. For a volume that also runs live broadcast, RedSpy adds ST 2059 genlock and sub-frame recovery.

Which is better for live broadcast?

RedSpy. It was built for the broadcast chain: 2 ms delay, tri-level, BnB and SMPTE ST 2059 genlock, FreeD output to every major broadcast engine, no drift and automatic recalibration after power-on. CinCraft Scenario is strongest on film sets and in on-location VFX where the priority is tracking without rigging and data for post-production.

Camera tracking comparison · 2026

RedSpy vs ZEISS CinCraft Scenario (formerly Ncam Reality)

Q: Which has the lower delay?

RedSpy publishes a data delay of 2 ms, or 0.1 frame at 50 fps, with output up to 250 fps. ZEISS describes CinCraft Scenario as very low latency but does not publish a figure. For a live signal path, test Scenario in your own chain before committing.

Two different answers to the same problem. RedSpy tracks the camera against retroreflective markers placed in the studio. CinCraft Scenario, the system ZEISS took over when it acquired Ncam Technologies in July 2023, tracks natural features in the scene and adds reflective or LED digital markers where the scene does not offer enough detail. This comparison is written by the team behind RedSpy and sticks to published specifications.

Sources: stYpe RedSpy specification; zeiss.com/scenario and docs-cincraft.zeiss.com; ZEISS press release of 18 July 2023; Film and Digital Times, August 2023. Where ZEISS does not publish a figure, the table says so.

At-a-glance comparison

Both systems deliver real-time 6DOF camera tracking for virtual production. The differences are in the tracking reference, the published performance figures and the lens and post-production workflow.

Where the systems diverge

Markers vs natural features

RedSpy reads retroreflective markers on the ceiling, walls or floor. Once the map exists the reference is absolute: the system locks within seconds of power-on, does not accumulate drift and does not care what the set looks like, which is why it is at home in green screen studios and on plain LED volumes.

CinCraft Scenario tracks natural features, the edges and textures already in the scene, and only needs reflective or LED digital markers where the scene is too uniform. That is a real advantage on location and on film sets where rigging markers is not an option. It is also why the system needs help on green screens and featureless walls.

Published performance for live use

RedSpy publishes the numbers a broadcast engineer needs: 2 ms data delay, positional resolution below 0.01 mm, recovery from tracking loss in under 0.2 s, up to 250 fps output, and SMPTE ST 2059 genlock for ST 2110 workflows.

ZEISS describes CinCraft Scenario as "very low latency" but does not publish delay, resolution, recovery or frame-rate figures in its current documentation. That does not mean the system is slow; it means you have to test it in your own pipeline before relying on it for a live signal path.

Lens workflow

CinCraft Scenario is strongest with ZEISS glass: Supreme Prime, Nano Prime, CP.3 and Master Prime lenses arrive with eXtended Data and are plug and play, and more than 200 templates cover other cinema and broadcast lenses, with 10 to 20 minutes of calibration per lens for anything else.

RedSpy is built around broadcast lens workflows: Canon and Fujinon internal serial encoders, external encoders for lenses without a readout, and absolute encoder ranges that survive power cycles, so a studio does not reset zoom and focus limits at every call time.

Where CinCraft Scenario still makes sense

If your work is film and episodic virtual production, you shoot on ZEISS lenses, and the tracking data has to end up in Nuke or Maya as much as in Unreal, Scenario is a coherent package: CamBar on the camera, Wrangler for recording, Export for post. The Ncam heritage in on-set VFX is real.

The honest call: RedSpy and CinCraft Scenario are not two versions of the same idea. RedSpy is a broadcast instrument with an absolute reference and published sub-frame figures. Scenario is a film-set tool that trades an absolute reference for freedom from rigging. Choose by the shape of your production, not by brand.

Switching from Ncam Reality or CinCraft Scenario to RedSpy

If you are considering a switch, here is what changes and what stays.

What carries over

Cameras and rigs - RedSpy mounts on any broadcast or cinema camera; the CamBar position on the camera is where the RedSpy unit goes.
Engine scenes - Unreal, Vizrt, Pixotope, Zero Density or disguise projects are not rebuilt; only the tracking source changes and RedSpy speaks FreeD.
Lenses - the same lenses work; calibration is redone once in the RedSpy workflow and then kept, because encoder ranges are absolute.

What changes

Markers go up - a one-time placement on the ceiling, walls or floor, then a map that is reused for the life of the studio. Installation takes marker setup plus about 6 seconds per square metre.
Absolute reference - no drift and no dependence on scene texture, so green screen and LED wall setups behave the same on every show day.
Live signal path - 2 ms delay, sub-frame recovery and ST 2059 genlock fit an IP broadcast chain without extra buffering.

Most teams switch between two productions. Our deployment team supports the first shoots so the workflow matches what the crew already knows.
