What have been the hiccups you've noticed when using Wifi TC? Not that I don't believe you, I just want to understand fully what the limitations are.
Second question, a tad toward the n00b side: How important is genlock/trilevel in addition to TC? I understand its application in a live-switch situation, to ensure all cameras capture a frame simultaneously. Am I correct in thinking that regardless of TC sync between cameras, without a common frame clock one camera has the potential to drift out of sync from others, just like two un-synced audio recorders might?
We will be certainly capturing the best audio we can on each camera, so we'll always have that as a backup to throw into Pluraleyes. My concerns with audio sync, which very well may be unfounded (and I can't know at this point, because I have little idea of what situations we'll encounter) are:
Mobile cameras might be in a location with unclear audio (ex. next to a PA, if there is one), or audio not loud enough for a reliable sync (many of these festivals may include acoustic/folk performances)
Sheer distance between cameras/recorders introduces delay, so sync is off a bit (also possibly caused by reflections in large, loud indoor venues)
I'll have a better picture of the problems I'll encounter once we get on the road. For now, I'm just brainstorming solutions so I don't have to worry, and because I can convince the team to spend a little grant money on infrastructure that will make our jobs easier. That being said, we're not rolling in cash; I doubt we'd be able to purchase more than 2 lower-end sync boxes, so your comment regarding rentals is highly valid and something I'll be looking into more.
