BZBGEAR BG-12GCSA PRODUCT MANUAL
Introduction
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.

BZBGEAR BG-12GCSA PRODUCT MANUAL
Troubleshooting
Most of the issues experienced by users are not from the USB capture device itself, but
from the sophisticated software and hardware combination of PC or laptop. Please follow
the following suggestions if help is required:
1. OBS is a popular USB capture freeware and has excellent compatibility. Please
download it and start with OBS if users are not familiar with USB capture devices.
https://obsproject.com/download
2. Due to the complexities of operating systems and computer hardware, different USB
ports on the PC or laptop may have different performance or limitations. Please try
all USB ports to see if there are any differences.
3. Please use the USB cable in the box. We do not guarantee the overall performance
when the USB capture box works with some other USB cables.
4. HDMI/SDI cable quality may also play an essential role when capturing video. Please
be sure that HDMI/SDI cable can do 4K2K@60 HDMI/SDI signal transmission or
better. Try different cables when the device is not able to work as expected.
5. If audio has noise when using the PotPlayer software, please adjust the audio
renderer to WaveOut on the software. The setting path is:
PotPlayer→Audio →Audio Output →Audio Renderer →WaveOut
6. If there are problems such as video flipping or wrong direction when using VLC
software, please rotate, flip or transpose the video in the VLC software to correct the
video. The setting path is:
Tool →Effects & Filters →Video Effects →Geometry →Transform
