Overlay details: Motion vectors: Arrows | Overlay details: SAD
In addition to displaying motion vectors for each reference, global motion data may also been shown. Global motion vectors and the difference between the global motion model and the block motion vectors may be viewed using the same mechanisms as used to display block motion vectors. The motion vectors selected in approximating global motion may also be displayed.
The -global flag selects the display of global motion. This can be used in conjunction with -motion_colour, -motion_arrow and -motion_colour_arrow flags. To display the difference between global motion and block motion vectors, the -global flag is replaced with -global_diff.
The same option flags are available as can be used with the display of block motion vectors.
Motion vectors used in the approximation of global motion and those rejected are displayed using the -global_inliers flag.
