I'll try it for you if you will send me some video.
I took this video in a freshly painted white racquetball court with 2.65" dark blue spherical Russian style juggling balls. I used a Garmin Virb action camera set on 720p60fps Ultra-zoom. Contrast between the background and the juggling balls should be maximized.
The camera was placed on top of a 7.5' door that opened into the racquetball court. I was standing 12 feet from the camera. I am 5' 11" tall.
A setup similar to this is necessary to optimize the video for processing.
