S_PixelMoshProvides a more controllable and broadly applicable simulation of datamoshing techniques, historically used to generate strange visual results by intentionally damaging mpeg encoded files. Includes simulation of I-frame removal (Flow) and P-frame replacement (Pulse). NOTE: This effect 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 Stylize category.

-
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.
