Magewell Pro Capture Hexa CVBS review

This is a source-based assessment of Magewell’s Pro Capture Hexa CVBS, part 11250 (manufacturer SKU 112500000), not a hands-on digitizing test. It is a six-channel standard-definition composite capture card for a very different job from the HDMI and SDI cards elsewhere in this library: bringing several legacy analog sources into one PCIe computer. The central buying question is whether your source really is composite CVBS and whether the modest SD resolution is appropriate for the material you need to preserve.

Six composite paths, carried through one DB25 connector

Magewell identifies six CVBS video inputs and six analog stereo audio pairs (left and right). The card presents them through one DB25 connector rather than six BNC jacks on its bracket. The manufacturer’s package list includes a DB25-to-six-A/V breakout cable, which fans that connector out into the six source paths. This is a materially different hookup from a normal six-BNC SDI card: check the supplied cable, label each branch and confirm how the source’s video and audio connectors map before designing a rack or cable harness.

CVBS means composite video. Do not confuse it with S-Video, component video, HDMI or SDI just because a source device can offer several of those outputs. A VCR, legacy camera or compatible analog security feed may provide composite, but a component-only or S-Video-only source needs a different capture route or an appropriate conversion stage. The six-channel count is useful when several separate analog feeds need to reach a single system; it is not evidence that the card accepts six modern digital signals or converts them into HDMI.

Standard definition is the hard boundary

The technical specification sets the input and capture-image ceiling at 720×576 pixels and the listed capture-frame-rate ceiling at 30 fps. It supports NTSC, PAL and SECAM and can automatically detect the composite video standard. That is a practical range for many legacy sources, but it is not a 1080p or 4K digitizer. The card includes cropping, scaling, de-interlacing, aspect-ratio and color-format conversion, yet scaling an SD source to a larger canvas does not restore detail that was never present in the composite signal.

The existing finder’s capture-rate choices start at 1080p60, so none represents the Hexa CVBS’s actual 720×576-at-up-to-30-fps mode. An analog-only finder result can still surface it for the correct source category; adding an HD capture requirement should correctly remove it. That makes the model a specialist candidate for legacy-video or multi-camera SD workflows rather than a substitute for a game-capture card. If a production needs a particular NTSC or PAL field treatment, exact de-interlacing, audio synchronization or preservation codec, check that full chain in the target software rather than relying on the card’s broad format list.

Check the PC and physical package

The Hexa CVBS is an internal PCIe Gen2 x1 board with a low-profile bracket. The technical sheet gives a board size of 118.16×68.88 mm without its bracket and maximum power consumption of about 6.12 W. A low-profile bracket helps with compatible small-form-factor systems, but it does not remove the need for an actual PCIe slot, the proper bracket opening and a clear path for the DB25 cable. Verify that the case can close with the breakout attached and that the cable can bend without pressing against neighboring cards.

The product page lists one Hexa CVBS card, one DB25-to-six-A/V cable and one low-profile bracket. It does not list source cameras, composite leads, storage or a separate monitor/output device. The U.S. authorized-dealer listing bridges the product name and part number; the manufacturer page supplies the SKU and package information. Match the part and cable package on the offer rather than assuming that every seller bundle includes the same extras.

Software supports multiple workflows, not one automatic outcome

Magewell lists Windows, Linux and Mac support and names OBS among compatible applications. Its detailed specification describes DirectShow and DirectKS on Windows, V4L2 and ALSA on Linux, and a broad set of other DirectShow/V4L2 streaming or encoding programs. Capture Express and the Magewell SDK are also part of the wider product software story. A conservative Windows/OBS plan is documented here, with a separate general Mac software/host arrangement and no unsupported HD mode. Before a multi-source installation, confirm how each app enumerates the six video inputs and their associated audio pairs, what format each source is producing, and how the chosen operating-system driver exposes the card.

The technical sheet describes independent stream settings for a selected input, multiple cards per system and two video-processing pipelines. Those statements are not a workload benchmark for six fully processed channels on a particular PC. The six-channel identity and connectors make this a credible multi-feed design, but host bandwidth, application behavior, capture configuration and storage are still system-level checks. The product’s SDI/HDMI-free signal path also means it has no documented HDMI passthrough or display output; a monitor must be served by the computer or a separate device.

How it differs from other analog-capable cards

Pro Capture AIO and the DVI-family devices in this library accept different selectable signals or breakout configurations, usually as one capture path per selected input. Hexa CVBS instead devotes its DB25 breakout to six composite video feeds and six analog audio pairs, while retaining a standard-definition ceiling. Choose it when channel count and legacy composite connections matter more than HD resolution; for one VGA, component, DVI or HDMI source, another model may have a closer connector and mode fit. The broader output/streaming range of unrelated models does not erase this card’s specific advantage or its SD limit.

Before choosing it

Confirm that all intended video sources provide composite CVBS in NTSC, PAL or SECAM, and identify the audio and video branch for each one. Check whether 720×576 at up to 30 fps meets the preservation or monitoring goal, whether the computer has a usable PCIe Gen2 x1 connection, and whether the low-profile bracket and DB25 breakout physically fit. Verify the operating-system driver and the app’s device routing before relying on six-channel concurrency. This model is not a match for HDMI, SDI, 1080p60 capture or HDMI passthrough. The published limitations and capabilities are drawn from model-specific manufacturer pages and a U.S. identity bridge; no product was personally installed, used or benchmarked, and no price, current stock or seller experience is claimed.
