Video buses

Overview

A video bus is a device output with a selectable source. Pixelrush records a cut whenever the source on a bus changes.

A device may have multiple buses, each tracked independently by Pixelrush.

Transitions

Some devices can transition gradually between inputs (dissolves, wipes, auto transitions). Pixelrush only records cuts. A gradual transition is logged as a cut at the moment the device reports the new input as the live source on that bus. A transition that lands back on the input it started from is not recorded.

Related features

• Recording sessions — a session is scoped to a single video bus.
• Timeline exports — include every cut on the session's bus.

Supported hardware
