well i just watched a vid a guy just posted that he filmed with a glide cam, and i went on thier site and checked it out cause i had never heard of it before, and there is a vid on the glidecam site which shows the diff, here it is, its a regular cam with a person running and filming vs. a regular cam with a glidecam 2000 pro with a guy running, i cant believe how stable and sturdy the shots are, its mind blowing how well the glidecam works!!!!!!!!!!!!!
