Phantom VEO 4K vs PIXBOOM Spark

Which high-speed camera suits the shot?

Robotface's Phantom VEO4K-990S is an established, RAM-buffered high-speed system with 72 GB of internal memory, 10GbE connectivity and a Cine RAW workflow. The PIXBOOM Spark takes a newer approach, with continuous recording to removable media and a lighter camera body. Neither is automatically the better camera: the right choice depends on resolution, frame rate, take length, lighting, lens package, monitoring and the post-production path.

The comparison below reflects Robotface's PIXBOOM Spark running firmware V1.1.0. PIXBOOM modes and output options can change with firmware, while Phantom performance varies by resolution and recording settings. Robotface will confirm the booked configuration before production.

Practical reasons to choose each camera

Choose Phantom for controlled tabletop and motion control

For repeatable product work, Robotface prefers Phantom. The operator can control the camera remotely, provide immediate laptop playback and offload selected footage while the crew resets the shot. Phantom is also the current motion-control choice because the robot can start and stop camera recording directly.

Choose PIXBOOM Spark for unpredictable or extended action

Robotface now prefers PIXBOOM for sports, wildlife and other action that is difficult to predict. Its continuous-recording design allows the camera to keep rolling beyond Phantom's roughly five-second maximum-resolution capture window, reducing the risk of missing an unrepeatable moment. It can begin another recording immediately after stopping, and tested in-camera playback has been smooth and reliable.

Explosions, impacts and drama workflows

The production workflow determines the choice. For drama or feature work where immediate playback into a VTR system is essential, Phantom is currently better suited, and normal reset time gives its operator an opportunity to offload memory. For action lasting beyond Phantom's maximum-resolution window, reduce Phantom's frame rate to extend its capture duration or choose PIXBOOM. Where immediate VTR playback is not essential, PIXBOOM can be an excellent option for a longer unrepeatable event.

VFX and repeatable passes

Phantom is the current preference for VFX-heavy motion-control work because it can provide sync that MRMC robot systems lock to across non-standard frame rates. PIXBOOM provides genlock and may suit productions working at frame rates supported by the genlock system, subject to testing the exact configuration.

Small crews and post-production

PIXBOOM's smaller body is easier for a small crew or tight location and can be handled by an independent camera crew without a dedicated Robotface operator. Playback can become fiddly when rigging blocks access to the top LCD, however, because Wi-Fi control is not yet available in Robotface's tested workflow. Phantom continues to require a specialist operator/technician.

PIXBOOM currently requires more post time: copy as much as 2.5 TB of PXBC media, convert it through PIXBOOM Cine to CinemaDNG, grade in DaVinci Resolve, then export ProRes or another delivery format. With Phantom, the operator offloads during the shoot while the crew resets; the backed-up Cine files are ready by wrap and open directly in Resolve.

Lighting at 850–1,000 fps

For product shots and close-ups, standard lighting packages can often achieve around T2.8–T4. Wider depth of field, larger diffusion frames and softer sources quickly increase the required output because diffusion absorbs exposure. Lighting a full studio or full-body talent beyond T2.8–T4 can move the production toward classic 9K HMI-scale fixtures. Undiffused outdoor daylight is generally comfortable for high frame rates. Every brief should still be assessed individually for shot size, stop, shutter, diffusion and flicker.

Initial Robotface image findings

Robotface compared the cameras side by side in natural light at 4096 × 2160, 850 fps, ISO 1600 and daylight white balance, using matched Cooke S4 lenses at approximately T5.6. The physical camera positions created slightly different framing. Phantom was exposed one stop over its camera setting, consistent with Robotface's ISO 800 exposure rating. Each format was adjusted through its native RAW controls in DaVinci Resolve.

PIXBOOM was very usable and not noticeably noisy at ISO 1600, while Phantom produced the cleanest result when exposed this way. The Phantom's monitored log image was much closer to the resulting file. PIXBOOM currently displays a Rec.709-style live image, which made highlights appear harshly clipped on set even though the CinemaDNG files recovered them beautifully in Resolve. In the grade, both cameras felt broadly even for highlight control, while PIXBOOM showed more exposed shadow detail out of the box.

Robotface found Phantom's overall image and out-of-box skin tones more pleasing, with the kind of familiar colour response often associated with ARRI cameras. The difference is close, as it is between many modern cameras, but Phantom remains the slight preference when that familiar production finish matters. No meaningful rolling-shutter versus global-shutter difference was visible in this particular test.

What should be tested before booking?

Confirm the exact frame rate at the required resolution, crop and aspect ratio; acceptable noise at the planned exposure; flicker-free lighting; lens coverage; trigger and sync requirements; maximum useful take length; media capacity; offload time; monitoring; and whether editorial and grading can ingest the resulting files without an avoidable transcode bottleneck.
