BZBGear BG-4K120CHA 4K120 Capture Box
The 4K120CHA is the capture box for a console or a PC that outputs beyond 4K60. The HDMI 2.1 input and loop-out run at up to 4K120 4:4:4, so the player sees the full frame rate on their own screen while the capture side hands 4K30 or 1080p120 to the recording machine over USB-C.
HDR10 to SDR conversion is done in the box, which avoids the washed-out capture that comes from feeding an HDR signal to software that is not expecting it. Audio comes from the HDMI embed or the 3.5 mm input, with 3.5 mm and TOSLINK outputs for monitoring. It is powered from the USB-C connection.
