Brightness

Multiplies the brightness of every point in a frame by a single scalar. The simplest way to fade a frame in or out without touching its color, geometry, or path order.

Ideas

• Animate Brightness with a Phasor or Envelope to fade a clip in and out on a cue.
• Wire an Audio Input (Loudness mode) into Brightness for a frame that pulses with the music.
• Use as a master gate on a section of the graph: route the frame through Brightness before Output to gate the whole scene with one signal.

Tips

• Brightness is sampled once per frame, not per point. All points scale by the same factor.
• The node is a no-op when Brightness equals 1.0. It returns the input frame untouched, so leaving it in the graph has no cost.
• Values above 1 are clamped to 1; values below 0 are clamped to 0.
