Sapphire Plug-ins for AVX2: MotionDetect

S_MotionDetect

Shows areas of motion in a clip. For each frame, finds the difference between the current frame and a previous frame, and optionally combines that with the original.

In the Sapphire Time category.


Inputs:

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

Background: Optional. The clip to use as background. The output of the effect is composited over this clip.

Mask: Optional. Interpolate between the result and the Source input. White areas use the result of the effect. Black areas use the Source clip.

Parameters:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Mocha: Default: 0, Range: 0 or greater.
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater.
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

Mocha Opacity: Default: 1, Range: 0 to 1.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off.
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Resize Mocha: Default: 1, Range: 0 to 2.
Scales the Mocha Mask. 1.0 is the original size.

Resize Rel X: Default: 1, Range: 0 to 2.
The relative horizontal size of the Mocha Mask.

Resize Rel Y: Default: 1, Range: 0 to 2.
The relative vertical size of the Mocha Mask.

Shift Mocha: X & Y,   Default: [0 0], Range: any.
Offsets the position of the Mocha Mask.

Bypass Mocha: Check-box,  Default: off.
Ignore the Mocha Mask and apply the effect to the entire source clip.

Show Mocha Only: Check-box,  Default: off.
Bypass the effect and show the Mocha Mask itself.

Combine Masks: Popup menu,  Default: Union .
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
Union: Uses the area covered by both masks together.
Intersect: Uses the area that overlaps between the two masks.
Mocha Only: Ignore the Input Mask and only use the Mocha Mask.

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

Brightness: Default: 1, Range: any.
Scales the brightness of the motion image.

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.

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

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.

Mask Use: Popup menu,  Default: Luma .
Determines how the Mask input channels are used to make a monochrome mask.
Luma: the luminance of the RGB channels is used.
Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.

Blur Mask: Default: 0.05, Range: 0 or greater.
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas. It has no effect unless the Mask input is provided.

Invert Mask: Check-box,  Default: off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.
