I made a video to show the difference between iPi vs. Perception Neuron, both are RAW exported data to BVH for biped use, unedited in either iPi Studio or 3ds Max.
Both were smoothed as much as possible with the internal tools of each program only.(I did not rename finger bones for PN file, sorry, wasn't needed as was 17 neurons, no finger tracking anyway, hands and fingers are the least of the worries.
This is also the maximum amount of foot stabilization offered/applied with PN's Free editor, I don't know what the Pro editor will offer, but it comes with all the the Pro Windows, just all not activated for use.

Perception Neuron ONLY offers its Free editor at this time for testing, the Pro editor has not even been released yet for use, even by purchasers, as I understand it.
If you want to download and test the free editor yourself, go here:
https://neuronmocap.com/quickstart ... Scroll to Downloads near bottom and click on Axis Neuron.
It comes with several RAW motion files for testing and limited editing capabilities.
I am using iPi Studio Basic version and 5 PS Eyes, with 2 move controllers for wrist tracking for highly accurate results. (See videos index under Female Dance for demos).
As you can plainly see, although PN may be real-time recording and tracking, the amount of clean up needed will take much longer than the entire recording and processing time of iPi Studio, which to this point took me 1.5 hours in iPi at 1.15 s/f and .85 f/s with my machine config. with very little clean up or adjustments needed when applied to a character is was performed to be on.
Also, PN does not export a biped friendly BVH file, but I found a text editing program called Replace Genius that works easy and only have to rename the bones once and put them in a buffer that will batch them to rename the next file quickly, will work for any bone naming convention you use,

If I had a bigger studio to set up in, I could get a 20ft x 20ft capture volume and get more movement area, but that isn't needed for most actions.
To be in comparison to me, I would have to spend hours, if not days cleaning up the export from PN and still wouldn't be as accurate as iPi puts out in Raw form BVH... (Talk about Tokyo Drift!)... No Thanks, I will stick with iPi Studio and hope they keep improving it, they are doing well so far to me.
Comparative suit to iPi or 18 neurons kit, (no gloves for finger tracking), runs $1000 + shipping cost and only to US and Canada as of now. Add $500 for Pro editor (when released) and external power supply at $$ and dedicated WiFi router at $$ and if you ordered it now, you wouldn't even get it until late August at the earliest and to be honest, I think they are going to charge a subscription for the Pro editor once released also at $500 yr. (That's not exactly stated on website, but has been stated before!)
But... the disclaimer that pricing may change without notice is a good clue!!
Other limitations are listed on their Website and FAQ's and Forum... I would fully read and check out the product if anyone is thinking of purchase.
States firmware updates are already needed to implement certain features, (not operational yet), and will come in time, which is understandable as all products go through this.
I hope this visually shows the difference in the 2 programs ... You tell me which looks more natural in RAW state :)
