1)My studio is 31 square meters, blind (no windows) with basic lighting bolbs. Do you suggest me to purchase a special lighting setup?
There are no special lighting requirements for depth sensors as color data is not used for tracking. However there are things that should be avoided:
- Reflective surfaces anywhere in the scene
- Certain materials in clothing seem to absorb emission which Kinect uses to measure distance. You can determine them when corresponding body parts appear as "missing data" (yellow color) on the depth image. Replace such clothing

2)What lighting device should I choose for optimized calibration?
If you plan to use PS Move to track head/wrist rotations, then you're good to use for calibration also. It produces a distinct light spot in a video.
If not, use any flash light in candle mode (when light radiates to all directions). Or make a light source similar to PS Move by placing a little light (like a single LED) into a ping-pong ball.

3)What is the optimized placement of the two kinents? One in front of the performer and one behind? I need your guidance on this.
Right. When area permits, the 180 degrees placement is usually optimal. Note that sometimes an ideal opposite placement (when sensors look directly to each other) leads to increased yellow noise on the depth picture. If you encounter such an issue, just turn one or both sensors a little bit until the noise vanishes.
Recommended placements for various number of depth sensors are listed in our docs

4)What kind of usb extension cord should I use for the adapter? Will I get jittery results if I exceed certain meter length? Inevitably one of the kinects will be pretty far away from the PC.
It looks like you missed one important thing about Kinect 2. Due to limitation imposed by Kinect SDK each sensor should be connected to a separate PC. It should not be very powerful, just meet the
hardware requirements for Kinect 2. Any relatively modern laptop with Core series CPU should fit.
Therefore, there is no need for USB extension cables for Kinect 2. If there are no power outlets near intended sensor position then better to use power extension cord to move a PC closer rather than USB extension. Extending USB 3.0 cable with Kinect 2 usually leads not to some noise in the data but to complete loss of signal.

5)Are 2 Kinects 2 enough to capture finger motion? I need finger motion.
Unfortunately, our software does not track fingers. Mocap Studio only has tools for manual key framing of finger poses.
Maybe you've seen finger tracking features of Kinect SDK. However, we don't make use of them as they are very limited and inaccurate for mocap.
If you absolutely need finger tracking then consider special glove-like solutions available on the market. You can use them side by side with our full body mocap.
