I have an idea for a ipisoft contest that might be beneficial to its user base.

Ipisoft or an expert user would supply a calibration file and video take. The take would be trackable on a basic level, but present interesting challenges for cleanup: occlusion, jitter removal, pinning, feet planting, keyframe refinement, prop manipulation, etc.

This would be a chance for everyone to take a stab at the same material. It would raise everyone's game, and make for meaningful discussion afterward about techniques and workflow.
The winner(s) would share their approach and make everyone better.

Since Ipisoft could study the same file, they'd get a lot more direct feedback of how the tools are working. They could see where most people get stuck.

As some of the better users already own a license, their prize could be a couple years of free upgrade, or whatever is equivalent to winning a license.

Anyone interested? If not a contest, it could be a community project we do on the forum.
