I've reviewed the iFootage Shark Slider combined with the S1A1 Motion Control in the past (video review seen here). This time we're adding on the X2 Head that allows for Pan and Tilt of the camera. With this, you have a fully motorized advanced 3-Axis Motion Control System that allows for accurate movements and positioning for Time Lapse and also incredibly silent for real time video use. Here's a quick video on how to use this system for that popular Parallax Tracking effect often used on B-cam setups during interviews.
The X2 Motion Pan/Tilt Head can also be used without the Shark Slider. So if you want a simple 2-Axis Motion Control Timelapse system, just throw it directly onto a tripod. Or use it at the end of a jib as a wireless motorized PT Head.
I personally have only dabbled in some of what this entire system offers, and it is capable of far more advanced functions that what I have shown. It's not the cheapest motion control system avialable, but it's incredibly accurate if you need to repeat shots, highly programmable, and best of all incredibly silent (important for those interviews).
