Not sure how many of you are following the 'Human Planet' television series, but it's something to look into. It's already pretty amazing what types of environments these film makers have to endure, but then at the end of the segment they always show some type of BTS of how they pulled off some of their camera movements. In one episode they showed how they setup a CableCam system to follow a man crossing over a turbulent river.
So now i'm interested in seeing if I can pull one DIY version off with a GH2 or at least a tiny version for a GoPro (you know just in case I run into a situation where i'm shooting over a turbulent river too). If you've got ideas for the best way to go about this, i'd like to see what you come up with. Here's a few interesting videos below on some motorized remote systems with pan heads.
Here's one below from Vimeo Member Photoship One, same guys who offer Helicopter mounted camera systems. Heck, if their version can support a GH2, I think it would do well in the market. On another note, with a motorized CableCam, has anyone attempted a motion control CableCam for super long TimeLapse?
