The WanMoveTracksFromCoords node creates a set of motion tracks from a list of coordinate points. It converts a JSON-formatted string of coordinates into a tensor format that can be used by other video processing nodes, and can optionally apply a mask to control the visibility of tracks over time.

Inputs

Parameter	Data Type	Required	Range	Description
track_coords	STRING	Yes	N/A	A JSON-formatted string containing the coordinate data for the tracks. The default value is an empty list ("[]").
track_mask	MASK	No	N/A	An optional mask. When provided, the node uses it to determine the visibility of each track per frame.

Note: The track_coords input expects a specific JSON structure. It should be a list of tracks, where each track is a list of frames, and each frame is an object with x and y coordinates. The number of frames must be consistent across all tracks.

Outputs

Output Name	Data Type	Description
tracks	TRACKS	The generated track data, containing the path coordinates and visibility information for each track.
track_length	INT	The total number of frames in the generated tracks.
