I wouldn't say that. It's quite good for a hobby film, but comparing it to real pros:
You've got a few shots where the focus wanders aimlessly and I wasn't sure what I was supposed to be looking at. Can the focus on an iPhone be fixed, like in a regular camera? (Effectively turning the autofocus off and keeping a fixed distance in focus, or having someone manually control the focus to track a specific action.)
Phones with tiny lenses can't be as good in low light as those with larger ones. The iPhones low light tricks tend to only work for stills, or leave visible artifacts. Many of the good aspects of shooting with a phone are mooted if you try to add lighting.
Zoom remains weak compared to what a camcorder can do.
I'm not aware that tripods with handle control exist for phones. I find this vital, so that I can keep my eyes on what is going on around me, rather then on the camera.
- I do wish Apple would make a camcorder. DSLRs are an awkward form factor for video, particularly event coverage. The market is wide open.
