The Galaxy Note 3 captures 4K at 30fps. Conformed clips (interpret in Premiere) at 25fps were dropped into a 1080p timeline. As shot, no color correction/grading done just scaling (50 percent mostly) to fit 1080p.
BTW, this is a test. I had my Galaxy Note 3 for a few months now but never shot any video with it. All the talk of 4K in the media the past few weeks including a Note 3 4K video by the ever-working Philip Bloom makes it hard not to be curious about what it's like to shoot in 4K. Well may be a poor man's 4K really shooting with a phone.
I don't have a 4K tv or monitor so 1080p is the final delivery target.
A couple of clips were left 100 percent crop (rock at 0:37 and tomatoes at 1:34). At 1:45 veggies at 80 percent. Clip at 1:33 was shot at 1080p 60 fps (Samsung called it 'smooth motion') and portion slowed down to 30 per cent just to see some slo-mo:) There is 720p at 120 fps on the Note 3 but I didn't try it.
Unlike the other modes on the Note 3, 4K mode doesn't have any stabilization at all. To keep out shaky footage (difficult to shoot handheld) I mount the phone on a tripod adapter. Unfortunately it was such a flimsy built adapter that shooting at the beach it was easily fluttering in the wind. The jitters caused by the wind can be seen in the beach footage.
I did mod the adapter later to fit in a cage that it was solid enough (backyard footage).
The autofocus at first was a pain, it hunts once in a while when recording. Didn't know that you have to start recording first before the focus locks on when a focus point was selected. Is it in the manual?
After this test and knowing more about the quirks of the phone's video mode I guess it is possible to get decent quality for 1080p delivery from the Note3. The GH4 is very tempting now and so is a 4K monitor and a 4K TV as well.... :)
