BlurMotionMask Similar to BlurMotion but scales the amount of blur by the Mask input. Performs a motion blur of the source clip between the specified From and To transformations. This can be used to perform radial zoom blurs, rotate blurs, directional blurs, or any combination of these. Inputs: Source:  The clip to be processed. Mask:  The amount of motion blur is scaled by this input for each destination pixel. Only the red channel of this input is used.

Parameters:

Effect:   Popup menu,  Default: Blur Motion Mask.
Selects between full color or monochrome result.

Blur Motion Mask:  blurs all the channels of the source input.

Blur Motion Mono Mask:  makes the source monochrome and then blurs the resulting single channel (faster).

From Z Dist:   Default: 1,  Range: 0.001 or greater,  Shared.
The 'distance' of the From transformation. This zooms about the Center location when Shift is 0. Increase to zoom out, decrease to zoom in. This parameter can be adjusted using the From Transfm Widget.

From Rotate:   Default: 0,  Range: any,  Shared.
The rotation angle of the From transformation, in degrees, about the center. This parameter can be adjusted using the From Transfm Widget.

From Shift:   X & Y,   Default: [0 0],  Range: any,  Shared.
The horizontal and vertical translations of the From transformation. This can be used for directional motion. If it is non-zero the center location becomes less meaningful. This parameter can be adjusted using the From Transfm Widget.

Exposure Bias:   Default: 0.5,  Range: 0 to 1,  Shared.
Determines the variable amount of exposure along the path between the From and To transformations. A value of 0 causes more exposure at the From end, 0.5 causes equal exposure along the path, and 1.0 causes more exposure at the To end. If you have bright spots on a dark background, a 0 value would cause the processed spots to be brighter at the From end and dark at the To end, and a 1.0 value would cause the opposite.

To Z Dist:   Default: 0.8,  Range: 0.001 or greater,  Shared.
The 'distance' of the To transformation. Increase to zoom out, or decrease to zoom in. This parameter can be adjusted using the To Transform Widget.

To Rotate:   Default: 0,  Range: any,  Shared.
The rotation angle of the To transformation, in degrees, about the center. Note that if the From and To Rotate angles are very different, the interpolation between them will become less accurate. This parameter can be adjusted using the To Transform Widget.

To Shift:   X & Y,   Default: [0 0],  Range: any,  Shared.
The horizontal and vertical translations of the To transformation. This can be used for directional motion. If it is non-zero the center location becomes less meaningful. This parameter can be adjusted using the To Transform Widget.

Blur Mask:   Default: 0,  Range: 0 or greater,  Shared.
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas.

Invert Mask:   Check-box,  Default: off,  Shared.
If enabled, inverts the mask input so the effect is applied to areas where the Mask is black instead of white.

Subpixel:   Check-box,  Default: on,  Shared.
If enabled, uses a better quality but slightly slower method for performing the blur.

Center:   X & Y,   Default: [0 0],  Range: any,  Shared.
The center of rotation and zooming, in screen coordinates relative to the center of the frame. The shift values should be zero for this location to make sense. This parameter can be adjusted using the Center Widget.

Wrap:   X & Y,  Popup menu,  Default: [NO NO].
Determines the method for accessing outside the borders of the source image.

NO:  gives black beyond the borders.

TILE:  repeats a copy of the image.

REFLECT:  repeats a mirrored copy. Edges are often less visible with this method.

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

Blur Res:   Popup menu,  Default: FULL.
Selects the resolution factor for the motion blur. This is similar to the general 'Res' factor parameter, but does a better job of averaging down to lower resolution and interpolating back up to the result. Higher resolutions give better quality, lower resolutions give faster processing.

FULL:  Full resolution is used.

1/2:  The motion blurring is performed at half resolution.

1/4:  The motion blurring is performed at quarter resolution.
