I do have some Mocap data from a few slinging motions, but I’m missing the speed of the ball, because it didn’t have a reflective marker.
(With the danger of repeating your thoughts

There should be a synchronized, timestamped video recording available for this MOCAP?
Two options:
a) Requirement: video from several known positions.
rewrite the code to do pattern recognition of the video to do triangulation onto the ball.
appropriate color channel separation, edge detection and centroiding should give a decent result for marker position for each camera channel. Then feed it as an additional marker point to the triangulation routine of the software. But I'm not sure if you have that deep access to the software
.
b) Requirement: video feed from single position with timestamp.
get the release time. approximate ball speed = pouch speed at release time. This will yield an upper limit for the ball speed.
