Using the Smart Vector Toolset

The Smart Vector toolset allows you to work on one frame in a sequence and then use motion vector information to accurately propagate work throughout the rest of the sequence. The vectors are generated in the SmartVector node and then piped into the VectorDistort node to warp the work. That way, you only need to render the motion vectors once.

Quick Start

The toolset workflow is outlined below:

1.   Connect the SmartVector node to the source sequence to generate the required motion vectors. You can also write them to file using the .exr format. See Generating Motion Vectors.
2.   Find a suitable reference frame and add the required paint corrections or an image to the frame. See Adding Paint to the Source or Adding an Image to the Source.
3.   Connect the VectorDistort node to the SmartVector node (or a Read node referencing the .exr files rendered from the SmartVector node) and the source sequence.
4.   Premultiply the VectorDistort output and merge it over the source sequence to complete the comp. See Applying Motion Vectors to the Source.
