Each output frame is the average of multiple input frames: from the current frame, back to a given number of previous frames. This is similar to the Trails effect, except all frames within the range are weighted equally instead of fading out, so the end points of the trails are abrupt. Each frame contributes only 1/n of the total brightness, so fast-moving objects against a dark background may seem dim.

The average is reinitialized whenever any non-consecutive frame is processed: either the first frame, reprocessing a given frame, or jumping to another frame. You must process multiple frames of a clip in a row to observe the effect, and clearing your image cache before rendering may sometimes be necessary. This effect does not work properly if processed on fields. Please be sure to process on frames.

In the Sapphire Time effects submenu.


Source:  The current layer.   The clip to be processed.


Ave Over Frames:   Integer,  Default: 10,  Range: 1 or greater.
The number of previous frames to average over, including the current frame. For correct results, this parameter should not be animated.

Brightness:   Default: 1,  Range: 0 or greater.
Scales the output brightness.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.
All Opaque:  Use this option to render slightly faster when the input image is fully opaque with no transparency (alpha=1).
Normal:  Process opacity normally.
As Premult:  Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.
