Model VDC-HDMI2USB-308 handles ultra-high-definition capture over USB 3.0. Recording reaches 4K@30fps or 1080P@60fps, and the HDMI loop-out passes 4K@60fps or 1080P@60fps to the display, letting local viewing keep a higher frame rate than capture on the same unit. HDMI and microphone enter the card; USB 3.0, HDMI and a 3.5 mm line-audio socket leave it. Bus power holds consumption below 2 W, the shell rates IP54, operation spans -10 to +50 Celsius at 10% to 90% humidity, conditions that suit ordinary studio and control-room settings, and the product measures 103x62x13 mm at 75.2 g.

Cabling mirrors the 1080P model: source into the HDMI input, monitor on the loop-out, and a single USB 3.0 lead carrying both transport and power, with microphone and line audio reaching the computer together with the picture. Win 7 and later versions, Linux and OSX run the card alongside OBS Studio, Windows Media Encoder, VLC, Wirecast, vMix and Potplayer. Note the recording ceiling of 4K@30fps against project needs, switch to 1080P@60fps when smoother motion matters, keep the monitor path at 4K@60fps; the loop-out is independent of the recording file, so viewing stays fluid even while capture runs at 4K@30fps, and audio reaches the machine through the matching 3.5 mm socket. Packaging occupies 169x108x55 mm at 268 g.
