After flying overnight to the Gold coast we filmed this over one and half days and play it at the end of the conference. It was mostly shot in 4K on a Canon 1DC but there are some HD clips in there. We edited on FCPX on a Macbook Retina and exported a 1080p h.264 file for playback on three screens.
The only delay was transcoding the files to Apple Pro-Res which took about six times the length of the clip. This camera excels in low light.
