Motion capture with markers

[dsantamonica]

Hi,
I made a motion capture test with markers :

First of all : I don't want to buy a kinect, I conceived my suit for free.
Now what's the best software for this kind of mocap, I tried Autodesk Matchmover, but it's rather disappointing, I saw on the net Optitrack ARENA and Motive, how are they ? (especially ARENA, even if it's replaced by Motive)?
Also "The Captury" looks good and doesn't require any marker, but I can't get it and it requires many cameras (I have 6 maximum, considering also webcam and smartphone) Yes, it's very homemade, but I can't do it another way (and I don't really want to).
What other software is there for that?
Any remarks about this test ? (don't forget it's a gif and the black fade was made very quickly, it's not definitive)
Thanks for your help

I installed Vicon Blade 2.0 and cleaned up the videos :

I import them in Blade, but then I don't know how to process and create 3D points.
I searched in the tutorials, on Google and in the software's help, but it's all about realtime capture, and I can't do it live with my 4 cameras

BUT IF I CAN IMPORT, I SHOULD BE ABLE TO USE IT, RIGHT ?
How can I do this ?
