Overview
The BG-12GCSA is a USB-C 12G-SDI video capture device with a scaler, HDMI 2.0/12G-SDI loopout, and audio that provides a professional way to capture SDI video signals. It adopts a USB 3.1 Type-C Gen 1 (USB 3.0) interface, which allows for high-speed data transmission. Additionally, the SDI input and loopout can support up to 4K2K@60.
Users can connect the BG-12GCSA to a 4K2K@60 source and capture Ultra HD (4K2K@30) video. Furthermore, this unit can capture and display original, uncompressed SDI video, with a more realistic color rendition. The BG-12GCSA uses large volume image buffer technology, which effectively avoids video tearing. The high sampling rate and accuracy ensure that the captured videos have a high degree of sharpness, rich details, and fewer color edges.
