The effect? Trying to simulate the effect of virtual 3D 'ribbons' coming from the dancers hands as though they are being drawn in the air. They would then either slowly float to the ground or disappear
I assume I could take the tracking data and import into AE for use by a Trapcode plugin.
Someone mentioned that Syntheyes or other 3d tracking tools, need a minimum number of points to track correctly. So if the dancer moves his-her hands as well as rotates them I'm not sure How I could track properly.
