An eight-lane PCI Express capture board with four separate video capture channels is the Datapath VisionHD4 Quad Video Capture Card. Additionally, this capture card records embedded digital audio from every channel, which may be precisely timed to the corresponding video capture channel. For control room, medical, and other applications that need a high capture bandwidth, this video capture card offers a high-performance and high-density video capture solution. Great 4K and quad HD solutions are made possible by the quad HD capture capabilities in conjunction with Datapath's multi-stream and synchronisation features.

General capture card features:

- 8 lane PCI Gen.3 bus
- 3.2 GB/s total capture bandwidth in 4 PCIe lanes Gen.3 or 8 lanes Gen.2
- 4 x Datapath capture processors
- Frame buffer memory 4 x 256MB
- Datapath unified Windows and Linux driver support
- All standard Vision range features

Quad DVI-I capture channel:

- HDMI/ DVI/ RGB/ YPbPr video capture
- Maximum resolution up to 4096 x 4096, at 165 MHz Pixel Clock (digital modes) or 170 Msps in analogue modes
- HDMI audio capture with streaming from each DVI channel
- 800 MB/s bandwidth per capture processor
