When importing video from my Humaneyes Vuze+ camera, a pop-up appears, requesting parameters for the default preset (which I have set up as Vuze), and the number of Clips Per Rig. What does this parameter do? Does it relate to the stitching GUI somehow, or to the imported footage and the number of lenses creating that footage? If it's the latter, this seems set at 6 by default, but my camera has 4 pairs of lenses for stereoscopic 4K 360 video. Should the parameter be 4 (as in, the left eye and right eye views each comprise input from 4 of the lenses), or 8 (as in, there are 8 lenses in total recording footage)?

Its 8

That parameter defines how many files are considered a take. In classic rig, every lens is recorded in a separate file, so if it had 6 lenses it will generate 6 files per take. I believe Vuze only generates 1 file per take, and that only file contains the 8 lenses. If that's the case, the number you're looking for is 1!
