Attach a front clip to the Motion Analysis tool to analyse image displacement in a frame with respect to the frame before it. Forward and Backward vectors can be output from Motion Analysis.
Regardless of bit depth, each output is a 16-bit floating-point image.
The Motion Analysis effect includes two additional views: Forward Vector and Backward Vector. In these views, motion is represented by a colourspace. The colour intensity increases to indicate a larger displacement in the sampled area.
| Colour | Type of Motion |
|---|---|
| Red | Horizontal motion |
| Green | Vertical motion |
| Yellow | Horizontal and vertical motion |
| Black | No motion |
(a) Motion data in the Forward Vector view
Motion analysis accuracy is determined by the Quality setting: you can process the image at its full resolution, or change the option to increase the processing speed.
Motion data from this tool can be input into other effects, such as Pixel Spread and Timewarp.
