Correcting poorly captured crouch 2d data

I'm having problems with specific shots when the actor is in a crouched position.

Upright, the capture works perfectly. In some crouched states however where markers invariably become occluded to some cameras, the skeleton breaks apart before reforming again sporadically. I might lose a leg in one instance, the whole body in another, before it rights itself.

As such I can't get a clean 2d pass to trajectorize. Am I able to force the skeleton to 'stick' in place, or fix this? If anyone could point me to the correct tutorial or offer advice I'd be grateful.

James:

You can try moving the shin markers from the front of the leg to the back, this might help some as the markers will not get occluded as much, which will help with the legs getting lost.

just a thought

Hello, thanks for your reply. I had noticed this option in the setups and will plan future shoots around crouched/standing shots to accommodate this setup.

What I was really wondering at this stage was whether the data I've shot is fixable in it's current form? Some shots have a good t-pose, good crawling section but the odd spell of a few seconds where the skeleton is partially or completely off target.

You should be able to traj. then fill in gaps/flipping markers within the 3d data.

Thanks Vincent, do you mean with the draw curve tools specifically? I'll try this.
