Sapphire Plug-ins for After Effects: DissolvePixelMosh

S_DissolvePixelMosh Transitions between two input clips using a dissolve while applying PixelMosh to the clips. The Dissolve Percent parameter should be animated to control the transition speed. NOTE: This transition is random by design. As such, please be aware that slight pixel differences between CPU and GPU renders may be noticeable. For the best results when applying S_PixelMosh to clips, please utilize a professional codec and file format, such as a ProRes QuickTime movie, as opposed to a web video codec that employs inter-frame compression, such as H.264 in an MP4 file format. In the Sapphire Transitions effects submenu. Inputs: Foreground: The current layer. Starts the transition with this clip. Background: Defaults to None. Ends the transition with this clip. If this input is not provided, a fully transparent background is used, showing whatever is behind it. Note that the background can not be warped during the transition unless this input is provided.

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.

Vary Hold Frame: Popup menu,  Default: Automatic .
Selects between Automatic and Manual animation of Flow and Pulse.

Automatic: Interval parameters control the animation of Flow and Pulse.

Manual: Frame parameters may be keyframed to control the animation of Flow and Pulse.

Transition Dir: Popup menu,  Default: Dissolve Off to Bg .
Selects the direction of the transition.

Dissolve Off to Bg: transitions from the current layer to the Background.

Dissolve On from Bg: transitions from the Background to the current layer.

Auto Trans: Popup YES-NO,  Default: No .
If enabled, a transition is performed automatically between the first and last frames of the layer. If this is off, the transition is performed manually by animating the Dissolve Percent parameter.

Dissolve Percent: Default: 0, Range: 0 to 1.
Auto Trans must be disabled for this parameter to be used. It determines the transition ratio between the Foreground and Background inputs, and would normally be animated from 0 to 100 to perform a complete transition. The curve controlling this parameter can be adjusted for more detailed control over the timing of the dissolve. The Slow In and Slow Out parameters, if positive, also adjust the transition ratio internally for a smoother start and/or end to the transition.

Dissolve Speed: Default: 5, Range: 1 or greater.
The speed of the dissolve between the From and To clips.

Slow In: Default: 0.2, Range: 0 to 1.
If positive, causes the transition to start more gradually.

Slow Out: Default: 0.2, Range: 0 to 1.
If positive, causes the transition to end more gradually.

Use Flow Warp: Check-box,  Default: on.
Enables Flow.

Frame Interval: Default: 15, Range: 0 or greater.
Time delay (in frames) between automatic Flow warp starts.

Vary Frame Interval: Default: 0.7, Range: 0 to 1.
How much to randomly vary repeating Flow intervals.

Flow Warp Hold Frame: Default: 0, Range: 0 or greater.
Which frame to manually start Flow warping.

Block Size X: Integer,  Default: 32, Range: 0 or greater.
Horizontal size (in pixels) of simulated macroblocks.

Block Size Y: Integer,  Default: 32, Range: 0 or greater.
Vertical size (in pixels) of simulated macroblocks.

Flow Warp Scale: Default: 2, Range: any.
Scales the amount of warp distortion.

Blur Flow: Default: 0, Range: 0 or greater.
Amount to blur the source frame before calculating optical flow.

Flow Field Smoothness: Default: 0.8, Range: 0 or greater.
Optical flow parameter: The relative importance of adhering to the image data relative to the importance of keeping a smooth flow field. The higher this value, the more relative importance is assigned to the flow field smoothness.

Emphasize Edges: Default: 0, Range: 0 or greater.
Optical flow parameter: Specify the degree of structure/texture decomposition to apply to the input clip prior to solving for the motion vector field. This can be useful to reduce problems due to lighting changes and may give better localised flows and other improvements. It is not recommended when there is fast motion in the input clip. However, in some cases, it can be very helpful in getting acceptable results. Suggested usage is to first try a value of 0.0 (which turns off structure/texture decomposition). If the result is unsatisfactory, try 0.4. Finally, try 1.0.

Flow View Scale: Default: 0.9, Range: 0 or greater.
When outputting a representation of the motion vectors, this increases the saturation of the color corresponding to a unit length motion. This makes the representation more sensitive to show shorter vectors more clearly.

Add Pulse Frame: Check-box,  Default: off.
Enables Pulse.

Pulse Before Flow: Check-box,  Default: on.
Perform Pulse (if enabled) before Flow.

Pulse Interval: Default: 10, Range: 0 or greater.
Time delay (in frames) between automatic Pulse starts.

Vary Pulse Interval: Default: 0, Range: 0 to 1.
How much to randomly vary repeating Pulse intervals.

Pulse Hold Frame: Default: 10, Range: 0 or greater.
Which frame to manually start Pulse.

Pulse Intensity: Default: 0.3, Range: 0 or greater.
Scales the intensity of Pulse.

Pulse Threshold: Default: 0, Range: 0 or greater.
Limits the extent of Pulse.

Pulse Block Size X: Integer,  Default: 10, Range: 0 or greater.
Horizontal size (in pixels) of Pulse elements.

Pulse Block Size Y: Integer,  Default: 10, Range: 0 or greater.
Vertical size (in pixels) of Pulse elements.

Pulse Combine: Popup menu,  Default: Add .
Determines how to combine the Pulse with the background.

Add: Causes the Pulse to be added to the background.

Screen: Causes the Pulse to be combined with the background using a screen operation.

Comp: Causes the Pulse to be composited over the background.

Overlay: Causes the Pulse to be combined with the background using an overlay function.

Ave: Causes the Pulse to be averaged with the background.

Min: Causes the Pulse to be combined with the background using a minimum function.

Max: Causes the Pulse to be combined with the background using a maximum function.

PulseOnly: Gives the Pulse alone with no background.

Pulse Bg Brightness: Default: 1, Range: 0 or greater.
Scales the brightness of the background relative to the Pulse

Seed: Default: 0.123, Range: 0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

Show: Popup menu,  Default: Result .
Selects the output option.

Result: Shows the result of the Flow and Pulse.

Source: Shows the input image being used as the source.

Flow: Shows the optical flow map.

Flow Vectors: Shows a representation of the motion vectors. The direction of the vector at a pixel is shown as a color, and the length of the vector as the saturation of that color.

Flow Blocky: Shows the flow map after it has been pixelated according to block size

Flow Coords: Shows the Flow warping coordinates.

Flow Warped: Shows the result of the Flow.

Hole Mask: Shows an automatically generated mask of any holes in the image created by Flow warping.

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.
