This video was filmed using the Samsung Galaxy Note 4 that records 4K video, this is the built-in 4K encode at 50mbitps, using the built-in microphone. Perhaps there is some good Bluetooth Microphone system that could be used for lapel-microphone and for handheld microphone, perhaps also a good shotgun microphone. Let me know in the comments if you know any good of these that could be used with 4K smartphones to record highest quality audio. I also would like to upgrade my camera on the steadicam to 4K, I like the idea of perhaps trying out the Samsung NX1 that can encode 4K in H265 at 40mbitps, or perhaps I'll wait for some other high performance 4K H265 camera, the idea being for the 4K footage to be compressed well enough in the camera so that the videos can be uploaded to YouTube directly. It seems though that http://youtube.com/editor doesn't support 4K rendering yet (meaning that when someone tries to join/split 4K videos with YouTube editor, it outputs only a 1080p maximum file? Can someone please report this to Google? Otherwise perhaps there would be a camera to offer native 4K H265 in-camera basic join/split editing, perhaps even also with support to automatically add intros, outros, overlay transparent watermark branding (even animated watermark branding). Dual SD card recording for backup (when SD cards break, which has happened too often for me).
