[...] They have to record sound separately for quality and location. They're definitely not using the internal mic on the phone.
I understand that. You may have missed the context in which my comments were made:
fastasleep suggested the production audio (the sound that is recorded separately) could be sync'ed to picture without time code by using software that compares the waveform of the production track to the "wild" sound captured by the microphone on the iPhone. I was simply pointing out some limitations imposed by that approach.
There's another one I didn't mention before -- that the sound captured by the iPhone may be so dissimilar to the production track, either because of distance or crew noise captured by the iPhone, that the software may not even be able to match them. This could be overcome by sending a feed of the production audio to the iPhone Lightning connector as a reference track, but then one might as well just send time code instead.
Well, we don’t know how big his audio post crew is or what software they’re using, so speculation about the details is kind of pointless. I just meant that there are methods beyond timecode that work, and you made it sound like they’d be running microphones directly into the iPhone used to shoot for production audio which I’m sure they did not do.
I'm not sure where anyone would get the idea that I was talking about recording production audio with the phone, since my comment was specifically about how the wild sound captured by the iPhone would DIFFER from the production track. That was the whole point.
Good points. Of course, doing all that means either tripling the size and weight of the iPhone with a pair of wireless receivers or tethering it with cables, either of which makes the experience less like what we associate with shooting on an iPhone and more like a traditional camera rig. It seems like that would defeat the benefit of using an iPhone in the first place.
Were you not talking about attaching audio hardware to the iPhone?

Gotcha, I see where the confusion arises. I was actually responding to @harsteins1 who suggested sending production audio to one channel of the iPhone and time code to the other to provide a reference for synchronizing sound and picture in post. If my comment is read alone it may seem like I was suggesting using the iPhone as an audio recorder, but not if read in context with the quote above it.
Even earlier in the thread I wrote:
Since audio isn't recorded in the iPhone, a method of syncing sound to picture is required.
Guessing he used the app called “Filmic Pro”? It’s the only app I know of that enables a reasonable range of options to fine-tune image capture to the point where it’s usable for professional use. This app was also used years ago for an Academy Award winning feature that was shot on an iPhone (the name of which escapes me).
So where is a good online write up that goes over what tools are available (and necessary) to shoot with an iPhone? Primarily concerned with audio and lenses.
