The Matrox VS4 provides up to four independent HD-SDI inputs in a single PCIe slot with up to 8 embedded audio channels per SDI source, taking up an absolute minimum of the precious real estate in your PC.  Letting you take advantage of professional broadcast video and audio sources for the utmost quality in your internet productions.

Matrox VS4 Features:

  • Full-size BNCs connect directly to your cameras.
  • Capture up to four HD-SDI video streams
  • Easy-to-use ISO recording - Recording all your video feeds is as important as streaming if post-event editing is required. The Matrox VS4 not only sends your video feeds to Wirecast for streaming, it simultaneously records all your original video feeds to disk.
  • The easy-to-use Matrox ISO camera recording tool lets you record using the high-quality Matrox MPEG 2 I-Frame codec at up to 300Mb/s in HD. You can then use Adobe Premiere Pro to natively edit your material.
  • Effortless onsite set-up - Just hook up your cameras, start Wirecast, and stream. Matrox VS4 automatically detects the presence, resolution, and frame rate of all your inputs so you don’t have to manually set up each source in Wirecast.
  • Because all inputs on Matrox VS4 are independent, you can use HD and SD cameras in the same production.
  • Expandable technology - Need more than four sources for your production? Simply add a second Matrox VS4 capture card to your system and you've increased your setup from 4 to 8 inputs.
  • Extensive audio support - Matrox VS4 captures up to 8 channels of embedded SDI audio on each input. Using Wirecast, you can choose any stereo pair for your streaming production while simultaneously recording all 8 channels to disk using the Matrox recording tool. You have complete flexibility to go from a simple stereo mix to surround sound for your post-event editing needs.
