That Steadicam Arm is amazing. I've seen some stuff on Amazon-eBay for 4th Axis - Z axis Stabilization which looks pretty cool. Me? I'm sticking with just adding stabilization in editing.
I have no advice except all the stuff I gleaned from the web and this site. (I am not an expert) From what I have read: Wide Angle Lens (Smooths out movements) Groucho Marx Duck Walk Use a wheel chair or skateboard Shooting with faster frame rate and slowing footage slightly in editing. Adding stabilization in editing. Follow a subject walking--- the viewer focuses on the person and the bobbing motion is less apparent.
