USB-C and data protocol
USB-C describes a connector shape. USB 2.0, USB 3 and their data rates describe the connection’s capabilities. Two USB-C ports can support different speeds, power arrangements and video functions. A cable or adapter must match the required job; a different plug can’t make your computer’s port any faster.

UVC
USB Video Class is a standard way for a camera-like device to expose video over USB. UVC support does not mean every output mode or manufacturer software feature works on every computer. A camera’s USB charging or file-transfer mode is not proof of live UVC video.

Capture versus passthrough
Capture is the signal delivered to the computer for recording or streaming. Passthrough is the signal sent onward to a display. A capture card may pass 4K60 HDR to a screen while delivering a lower-resolution SDR capture to USB. Compare these paths separately.

Loopback
Loopback returns computer playback to an input that software can record or route. It can help capture applications, music or calls. The exact channels and exclusions depend on the device or software configuration; the word alone does not prove a safe guest return.

Mix-minus
A mix-minus is a mix with a particular source left out. For a remote guest, the return normally excludes that guest’s incoming voice so they do not hear themselves delayed. You set it up for each person you send sound to; it isn’t just a microphone mute or another word for loopback.

Direct monitoring
Direct monitoring sends an input to a headphone or other output without relying on the full software monitoring round trip. It helps you hear your microphone, but does not prove that the audience receives the same mix. Record and replay the actual broadcast output.

HDCP
HDCP protects certain HDMI content. The capture cards we cover need an unprotected signal. An HDMI socket does not make protected movie or streaming-app output capturable, and this site does not provide a protection-bypass method.

Clean HDMI and continuous power
Clean HDMI is a live feed without unwanted interface overlays. Continuous power means the chosen camera power arrangement supports the camera while it operates; charging while switched off is a different claim. Check both before you plan around an HDMI camera.

Cost so far
Cost so far adds up only the prices you entered. Parts without a price are counted separately, so it isn’t the full cost of your setup until every piece of hardware, cable and mount has a price.
