Staging the right video footage is also key to capture everyone. Thats why I went up in front and then slowed down and waved everyone forward and then moved up again.
My walk around the cars still needs some work as it seems I bounce up and down too much.
Post production is key also to cut out stuff not need and show the best footage.
My camera is first generation ContourHD. The newer cameras have better configuration options, wind noise cancellation and other nice to have like syncing with iphones.
recent video where I even added pics. It has a mixture of older video ... bouncy video footage of cars driving by as I was hand holding the camera and then mounted camera video footage that is speed up.
