Dual-channel 4K HDMI capture on a single PCIe card with dual loop-throughs.
The Magewell Pro Capture Dual HDMI 4K Plus LT is a professional-grade, dual-channel PCIe capture card designed for high-end video ingest. Its standout feature is the “LT” (Loop-Through) capability, which allows you to pass video signals through to a monitor or secondary device without needing external splitters.
Dual 4K60 Capture: Simultaneously captures two independent channels of video up to 4096×2160 (DCI 4K) at a smooth 60fps.
Integrated Loop-Through (LT): Features two HDMI loop-through outputs that mirror the input signals. This allows you to send your 4K video to a local monitor or another device without needing expensive external 4K splitters.
Dual Video Engine: Each channel has its own dedicated hardware pipeline for up/down scaling, 10-bit color processing, and de-interlacing, ensuring that the high-bandwidth 4K data doesn’t overwhelm your computer’s CPU.
High-Bandwidth Interface: Uses a PCIe Gen2 x8 host interface, providing the massive data pipe (approx. 1600MB/s per channel) required to move uncompressed 4K60 video into your software without stuttering.
