Single-channel 4K60 HDMI PCIe capture with HDMI loop-through.
Ask us a quick question about this product — signal compatibility, use case fit, or anything technical. We usually reply the same day.
The Pro Capture HDMI 4K Plus LT is the HDMI 4K Plus with an added zero-latency HDMI loop-through output. That single addition opens a new use case: capture the 4K60 signal while a local monitor or downstream HDMI equipment continues to receive the same signal in real time.
For broadcast galleries this matters because the captured signal often needs to remain visible on a confidence monitor or feed into a downstream switcher. For corporate AV in conference rooms, the loop-through means the live camera feed continues to display on the room's main screen while the capture happens for streaming or recording.
Aside from the loop-through, the card is identical to the Pro Capture HDMI 4K Plus — same FPGA pipeline, same form factor, same broadcast-grade colour handling. If you don't need local monitoring of the captured signal, the standard 4K Plus is a more cost-effective choice.
