MSU Motion Estimation Filter

MSU Motion Estimation Filter - VirtualDub plugin for motion estimation and compensation in a video stream VirtualDub MSU Motion Estimation Filter is a useful tool that performs motion 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.
Horizontal maximum motion - maximum length of motion vector's horizontal projection. Can take on values from 1 to 100.
Vertical maximum motion - maximum length of motion vector's vertical projection. Can take on values from 1 to 100.

Block sizes - Block sizes used in motion estimation.
Maximum block size - maximum size of a block.
Minimum block size - minimum size of a block.

Motion estimation algorithm - the algorithm of motion estimation.

Horizontal precision - horizontal precision of motion vector search.
Pixel - pixel precision.
Half pixel - half pixel precision.
Quarter pixel - quarter pixel precision.

Vertical precision - vertical precision of motion vector search.
Pixel - pixel precision.
Half pixel - half pixel precision.
Quarter pixel - quarter pixel precision.

Output - output of the filter.
Show compensated frame - show frame after motion compensation.
Show residual after motion compensation - show the residual between the original frame and the compensated one.
Show residual without motion compensation - show the residual between the original frame and the previous one.
Show MVs - show macroblocks' partition and motion vectors (the mode is unavailable if Show residual without motion compensation is chosen).

Extra - extra settings.
Borders allowed - allow compensation from blocks, exceeding the frame borders.
Colorspace - the colorspace to perform motion estimation in.
Halfpel interpolation algorithm - the algorithm of half pixel interpolation.

Log - logging of filter statistics.
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.
