I myself am the artistic type, and was unsure where to look for help, so I'm posting here. I'm trying to build a camera rig to spin around 10 pounds max with a 10ft. diameter at 300rpm. I'm wondering what exact forces are required to do such a thing. If anyone needs more specifics please let me know what they would be, and I'll provide them. I'll now explain exactly what I'm trying to do....I want to ceiling mount, or just basically mount above talent, a camera rig to re-create the matrix style movement. I'm planning on using a Casio EX-F1 camera at 300 frames per second, which at 300rpm should take about 30 pictures in a 1/10 second period on a 180, and when played it should effectively re-create the "matrix" style of slow-mo kind of effect. I want to use an electric motor which has a long straight piece attached to the shaft that is a total of 10 feet in length. This piece would have the camera mounted on one side, while the opposite side would have an amount of weight equaling the other side(camera and mounting equipment), to balance the rig. Any ideas? Thanks a BUNCH in advance.
