I shot this using a Sony HDR SR-11 using the maximum resolution 1920x1080/60i "HDFH" setting and 5.1 audio. Other settings were left to auto. I converted this in vegas 8 to an AVCHD MP4 at 1280x720/30P for vimeo. I'm not sure if the 5.1 audio was retained after the conversion.
Thanks and enjoy the video.
