Free video motion detection algorithm software for windows

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.
Main features:
Search area - area of motion vector search.
- Horizontal maximum motion - maximum length of motion vectors horizontal projection. Can take on values from 1 to 100.
- 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.
- 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.
