Datapath VisionSC-UHD2 video capturing device Internal PCIe

Datapath VisionSC-UHD2 is an internal PCIe video capture card designed for professional AV installations that require high-resolution, colour-accurate video capture. The card provides two independent HDMI 2.0 capture channels with HDCP2.2 support capable of 4K at 60 fps with 4:4:4 chroma sampling, and includes a 2 GB frame buffer and an eight-lane PCIe Gen3 host interface for high bandwidth capture.

Advantages

The VisionSC-UHD2 offers low-latency capture, advanced hardware scaling with polyphase multi-tap filtering for high-quality downscaling and accurate pixel replication when upscaling, and a full 10-bit processing pipeline. It supports Vision Performance features such as LiveStream, MultiStream, hardware timestamping, HDMI signal conditioning for extended cable runs, automatic mode detection and frame-synchronised ganging of inputs. Unified driver support is available for Windows and Linux.

Suitable for

• Control rooms and command centres requiring detailed, colour-accurate feeds
• Digital signage and reception displays showing high-resolution content
• Collaboration and meeting room systems that need multi-input capture
• Live production, streaming and capture workflows using DirectShow, Media Foundation or V4L compatible software

When it may not be suitable

This internal PCIe card requires a compatible host system with an available eight-lane (or higher) PCIe Gen3 slot and sufficient chassis depth (card dimensions: width 110 mm, depth 177 mm). It is intended for professional installations and may be unnecessary for simple consumer recording needs where single-channel USB capture devices are sufficient.

Key specifications

• Inputs: Two independent HDMI 2.0 capture channels with HDCP2.2 support
• Maximum capture: 4K @ 60 Hz with 4:4:4 chroma sampling on each channel
• Host interface: Eight-lane PCIe Gen3 (net capture bandwidth ~6 GB/s)
• Frame buffer memory: 2 GB
• Processing: Full 10-bit pipeline
• Onboard features: Hardware scaling with polyphase multi-tap filtering, colour space conversion
• Compatibility: Drivers for Windows and Linux; supports DirectShow/Media Foundation and V4L
• Cable support: HDMI certified premium cables up to 5 m with HDMI signal conditioning

How to use

Install the VisionSC-UHD2 into an available PCIe Gen3 x8 (or larger) slot in a compatible host PC. Connect HDMI source devices to the two HDMI inputs using certified cables (up to 5 m recommended for optimal signal integrity). Use Datapath drivers and SDK or compatible DirectShow/Media Foundation/V4L applications to access capture streams. Configure capture settings—resolution, frame rate, colour space and buffering—through the chosen software or Datapath utilities to match your workflow.

What to consider before purchase

• Ensure the host PC has an available PCIe Gen3 x8 (or larger) slot and adequate chassis clearance for a card 110 mm wide and 177 mm deep
• Confirm your software is compatible with DirectShow, Media Foundation or V4L drivers
• Plan for cable lengths up to 5 m or use HDMI signal conditioning for longer runs
• Evaluate whether dual 4K capture and the 2 GB frame buffer meet your performance and latency needs

Usage recommendations

For reliable 4K60 4:4:4 capture, use high-quality HDMI 2.0 certified cables no longer than 5 m where possible, install the latest Datapath drivers, and ensure the host system provides sufficient PCIe bandwidth and CPU resources for your capture and encoding workflow.
