Tracking
Keeo ISO as low as possible without under exposing to get less noise in your image
Have a higher shutter speed to minimize motion blur to make tracking easy.
Aperture needs to keep the subject in focus also keep the green screen out of focus
Make sure to note all of your camera details like focal length and sensor width to help with the tracking.
Measure distance from camera sensor to markers
Smoke obscures trackers
Flickering lights interupt trackers
LOG footage is annoying to work with.
Issues Chris encountered in his first try:
Fingers too complex to track
Trackers are hidden by arm rotation
specularity of Ink caused track to get lost
No good reference for scale
Too much motion blur. adjust shutter angle/speed
Second test:
felt balls are too large and featureless
shadow caused trackers to get lost
coloured lights also cause trackers to get lost
