Temporal: MotionDetect In the S_Temporal Plugin. Shows areas of motion in a clip. For each frame, finds the difference between the current frame and a previous frame. Inputs: Source:  The input to process. In Batch, it is recommended that this input be a clip of frames rather than another node.

Parameters:

Delay Frames:   Integer,  Default: 1,  Range: any.
The number of frames back to get the previous frame which is compared to the current frame.

Scale Result:   Default: 1,  Range: 0 or greater.
Scales the brightness of the result.

Saturation:   Default: 1,  Range: 0 or greater.
Scales the color saturation of the motion image. Increase for more intense colors. Set to 0 for monochrome.

Offset Darks:   Default: 0,  Range: any.
Adds this gray value to the darker regions of the motion image. This can be negative to increase contrast.

Motion:   Popup menu,  Default: All.
Selects between different motion types to detect.

All:  shows all motion, both increasing and decreasing brightness levels.

Brighter:  shows only motion in which the brightness is increasing, for example the leading edge of an object moving over a darker background.

Darker:  shows only motion in which the brightness is decreasing, for example the trailing edge of an object moving over a darker background.

Combine:   Popup menu,  Default: Motion Only.
Determines how the motion image is combined with the original source.

Motion Only:  gives the motion alone.

Mult:  the motion is multiplied by the source.

Add:  the motion is added to the source.

Screen:  the motion is blended with the source using a screen operation.

Difference:  the result is the difference between the motion and source.

Overlay:  combines the motion and source using an overlay function.

Subtract:  subtracts the motion image from the source darkening those areas.
