Main Time
Chooses the timing interpretation such as Real Time, Time Speed or Time Stretch.
For ordinary averaging start with Real Time.
Temporal average and echo
Averages several frames over time to reduce random variation or create soft temporal trails and ghosting.
Average is a temporal effect that samples multiple frames rather than blurring only the current image. This can suppress random noise on static areas or deliberately accumulate motion.
Overview
Number of Frames determines how many time samples participate in the average. Preceding Frames controls how much of the sampling window is placed before the current moment.
Frame Step spaces samples farther apart when increased, changing a smooth average into a more separated echo-like look.
Because real motion appears in different positions across sampled frames, strong movement produces visible trails. That is expected behavior rather than a spatial-blur artifact.
Think of Average as placing several neighboring frames on top of one another and calculating their mean: random noise fades, while moving objects leave a temporal footprint.

Inspector
Start with these controls before reaching for more complicated workarounds.
Chooses the timing interpretation such as Real Time, Time Speed or Time Stretch.
For ordinary averaging start with Real Time.
Sets the number of samples used in the average.
Higher values create stronger smoothing and longer motion accumulation.
Controls how much of the sample window lies before the current frame.
Sets spacing between sampled frames.
A value above 1 creates a more separated echo pattern.
Controls whether the current frame participates in the average.
Defines how samples beyond source boundaries are handled.
Ignore is often safer than Black when you want to avoid darkening clip edges.
Sets how strongly the processed result is mixed into the image.
Selects which RGBA channels are processed by the node.
Practical setup
Start with Main Time = Real Time.
Use a small Number of Frames first.
Set Frame Step = 1 for smooth averaging.
Choose boundary behavior that does not darken the clip unexpectedly.
Reduce Blend or frame count if motion becomes too smeared.
Examples
Average a small number of neighboring frames before the final grade.
Increase frame spacing and sample count for an intentional echo.
