Broadcast and Studio Video Capture: 4K, SDI, and HDMI

Broadcast and studio workflows demand robust capture from SDI and HDMI sources, often at 4K and high frame rates. When you're feeding a live show or an OB truck, "it usually works" isn't good enough—you need kit that's built for the job. Magewell's USB Capture family includes 4K-capable and SDI models that integrate with standard production and streaming software, so you can ingest without the footprint of full-size PCIe cards.

What Broadcast and Studio Need

Live TV, OB trucks, and studio control rooms need reliable ingest from cameras and graphics. USB capture devices that support 4K60 and SDI allow production PCs to receive broadcast feeds without full-size PCIe cards—handy for compact OB setups, backup ingest, or dedicated streaming PCs alongside traditional broadcast infrastructure. When the main router or switcher is SDI, an SDI-capable Magewell brings that feed into the PC; when you're dealing with HDMI from a camera or graphics machine, the HDMI line does the same. Same driver-free, UVC-style workflow either way.

  • 4K60 capture – Available in higher-tier Magewell USB Capture models for 4K workflows. HDR passthrough where the product supports it.
  • SDI support – SDI input models for direct connection to broadcast cameras and routers. No HDMI-to-SDI converter required when your plant is already SDI.
  • Software compatibility – Works with vMix, OBS, and other production tools that accept UVC or similar sources. Fits into existing pipelines without custom integration.

Choosing the Right Device

For 1080p HDMI-only workflows, the USB Capture HDMI Gen 2 is the workhorse—and it's the same device that streamers and educators use, so you're in good company. For 4K or SDI, step up to the USB Capture 4K or SDI product lines. Resolution, colour depth, and input count all vary by model; our product pages detail specs and compatibility. Contact us if you're matching a device to an existing router or switcher—we can help you get the right interface and cable length.

OB and Mobile Production

Outside broadcast and mobile units often need to keep weight and power low without sacrificing quality. USB capture fits that bill: small form factor, bus-powered where the model allows, and no PCIe slot required. Run a laptop or a compact PC with a few Magewell devices and you've got multi-camera ingest for streaming or recording. Same devices can serve in the fixed studio Monday and in the truck on Saturday—flexibility that broadcast and production companies use every day.
