I just got the Cinetic's CineMoto Rail System. This video demonstrates the smoothness of this affordable dolly product. I shot the piece with my Canon 7D and the video has not been graded. Aside from the need of a "How To" video that Justin Jensen, Cinetics Founder informed me they are working on, the product works like a champ. Some of the shots demonstrate the camera on the rail system and others will show the camera mounted on the CineSkates platform that enables various curves and tracking shots on flat surfaces. I spent more time with the CineMoto today than I did with the camera, so I am sorry if the picture is not as pristine as I am accustom to. All in all, I am very pleased with the unit and look forward to doing time lapse with movement next.
