VisionSC-SDI4 Capture Card

  • Four channel 3G-SDI capture card
  • 1080p HD video capture at 60 frames per second
  • PCIe Gen.3 for 2.97 GB/s capture bandwidth per channel

Developed for capturing multiple High Definition SDI video signals, the VisionSC-SDI4 is the perfect solution to AV professionals looking to capture from multiple SDI sources.

Ideal for use in broadcast markets or with any SDI capable applications the VisionSC-SDI4 provides four 3G-SDI inputs each capable of capturing 1920x1080p at 60 frames per second. Each capture channel is hardware timestamped allowing for larger surfaces to be captured and stitched together.

Video Streaming
DirectShow drivers for WDM Streaming supports the following applications, to encode, record and stream video over networks or the Internet:

  • Microsoft Media Encoder®
  • VLC
  • VirtualDub
  • Any other DirectShow encoding software

For streaming applications, the VisionSC-SDI4 can be used with Windows Media Encoder to compress and stream captured video. To replay the video, use Windows® Media Player.
Any application compatible with Windows® DirectShow technology can use the VisionSC-SDI4 due to its built-in WDM support
