Keep bright pixels from previous frames and decay them like CRT phosphor or oscilloscope persistence.

How it works

Temporal Phosphor Persistence keeps bright pixels from prior rendered
frames and decays them into the current frame. It is useful for CRT afterimages,
oscilloscope traces, HUD persistence, and high-contrast light retention.

Location

Temporal / Frame-to-frame / Phosphor Persistence

Controls

Choose Video mode. This effect uses previous frames, so play forward to inspect it.

Actions

Space plays or pauses. Use the timeline to choose a time.

Parameters

Control	What it does	Default	Range	Nudge	Animation
Blend	Sets how strongly this effect is blended with the source image.	0.75	0 to 1	0.01	Continuous keyframes
Decay	Decay setting for this effect.	0.86	0 to 1.25	0.01	Continuous keyframes
Frames	Frames setting for this effect.	8	1 to 16	1	Continuous keyframes
Intensity	Sets how strongly this effect is blended with the source image.	0.9	0 to 2	0.01	Continuous keyframes
Threshold	Cutoff used by the selected mode.	0.22	0 to 1	0.01	Continuous keyframes
Uses Temporal Frames	Uses Temporal Frames setting for this effect.	On	Panel-defined	Continuous	Panel-dependent
