Motion Analysis
Use Motion Analysis to analyse image displacement in a frame with respect to the frame before it.
Motion Analysis proposes two different algorithms to analyze displacement. Pick the one to use from the Mode box.
- Global analyzes the motion globally. It offers a greater stability in full-frame motion without the warping the results. It also exposes a few extra parameters that you can animate over time to get the best motion flow. GPU-bound.
- Local uses a neighbour approach. Best with localized motion, but loses precision with fast motion. CPU-bound.
To access the Motion Analysis menu, use:
- Batch, then select a node from the Node bin.
- Timeline, then use Batch FX. See Creating Batch FX.
- Tools, then select from the menu. See Accessing Tools.
This node accepts a front clip, and outputs forward and backward vectors.
