You can tell by the vignetting and the stability of the camera that it's a bullet [lipstick] camera. I infinately prefer to use the bullet camera. You can set it all up before the captain even gets into the aircraft, and it's a simple one-touch record and one-touch stop button.
It records better footage because of the angles of view, etc., and even records the audio. So: safer AND better. If you're serious about making flying videos, as far as I'm concerned it's the only way to go.
