VirtualDub MSU Motion Estimation Filter

VirtualDub MSU Motion Estimation Filter is a useful tool that performsmotion estimation and compensation in a video stream. It allows to show macroblocks partition and motion vectors as well.
Here are some key features of "MSU Motion Estimation Filter":
Search area - area of motion vector search.
ï¿­ Horizontal maximum motion - maximum length of motion vectors horizontal projection. Can take on values from 1 to 100.
ï¿­ Vertical maximum motion - maximum length of motion vectors vertical projection. Can take on values from 1 to 100.
Block sizes - Block sizes used in motion estimation.
ï¿­ Maximum block size - maximum size of a block.
ï¿­ Minimum block size - minimum size of a block.
Motion estimation algorithm - the algorithm of motion estimation.
Horizontal precision - horizontal precision of motion vector search.
ï¿­ Pixel - pixel precision.
ï¿­ Half pixel - half pixel precision.
ï¿­ Quarter pixel - quarter pixel precision.
Vertical precision - vertical precision of motion vector search.
ï¿­ Pixel - pixel precision.
ï¿­ Half pixel - half pixel precision.
ï¿­ Quarter pixel - quarter pixel precision.
Output - output of the filter.
ï¿­ Show compensated frame - show frame after motion compensation.
ï¿­ Show residual after motion compensation - show the residual between the original frame and the compensated one.
ï¿­ Show residual without motion compensation - show the residual between the original frame and the previous one.
ï¿­ Show MVs - show macroblocks partition and motion vectors (the mode is unavailable if Show residual without motion compensation is chosen).
Extra - extra settings.
ï¿­ Borders allowed - allow compensation from blocks, exceeding the frame borders.
ï¿­ Colorspace - the colorspace to perform motion estimation in.
ï¿­ Halfpel interpolation algorithm - the algorithm of half pixel interpolation.
Log - logging of filter statistics.
ï¿­ The following indexes are saved: the time of filter execution, FPS, the algorithm of motion estimation, motion vector search area, allowed block sizes, a mean number of SAD calculations per pixel.
