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. ￭ 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.
