S_DissolvePixelMoshTransitions between two input clips using a dissolve while applying PixelMosh to the clips. The Dissolve Amount 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 category.

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.
- Manual: Frame parameters may be keyframed to control the animation of Flow and Pulse.
-
Automatic:
Interval parameters control the animation of Flow and Pulse.
-
Dissolve Amount:
Default:
0,
Range:
0 to 1.
The transition ratio between the From and To inputs. Auto Trans must be disabled for this parameter to be used. This would normally be animated from 0 to 1 to perform a complete transition, and the curve 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.
-
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:
any.
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:

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.

Integer, Default:
10,
Range:
0 or greater.

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.
