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.
- Intersect: Uses the area that overlaps between the two masks.
-
Union:
Uses the area covered by both masks together.
-
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.
- Brighter: shows only motion in which the brightness is increasing, for example the leading edge of an object moving over a darker background.
-
All:
shows all motion, both increasing and decreasing brightness levels.
-
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.
- Mult: the motion is multiplied by the source.
-
Motion Only:
gives the motion alone.
-
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.
- Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.
-
Luma:
the luminance of the RGB channels 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.
