Additional thoughts on how to get your correspondent’s in to your control room from various locations.
One way that’s simple but low-rez is to do it via ichat or other webcam chat software., and record that at your location with a screen recorder or a tape capturing off of a scan converter hooked to your VGA out. That’s going to look pretty gritty if you have more than two people on cam at a time, unless you have very high bandwidth.
There are ways to cheat around this, but they all cost time or money. Here’s one way, not the only way, but one way I would look at producing such a show:
I would hook up all the participants by iChat or at least on audio via regular conference call or Skype. I would have each location roll an honest to goodness camcorder to do a capture of each person speaking in highest local quality possible. Conduct your multi-person conversation any way you like, while all cameras are rolling at all correspondent’s locations. Record the conference call locally.
After the conferencing is done, have the remote folks burn their tape to DVD or compress it in high quality and FTP it to your home base, unedited. If they lack that ability, or you have more time, they can all just mail you their DV tapes.
You then set up a multitracked, multicam synched edit at home base and re-create the visuals in high quality, using the master recording of the live low-rez conversation as the template.
This is time-intensive but otherwise inexpensive. You also could not do the show live this way for your audience.
I got this idea from a technique they use in public radio when they want a high-quality remote radio interview, but don’t have an ISDN line to the location.
They have someone roll a quality mic and tape or CD locally, while the interview is conducted by regular old nasty-sounding phone. The high-quality audio recording is then mailed or FTP’d to the NPR studio and someone re-edits it along with the reporter or host that was on the initial other end of the call. (Obviously, they already have a recording of that side from the actual event.)
Line up the two tracks in synch, then you can cut it any way you need while retaining a quality level comparable to the two people being in the same booth the whole time.
My version just adds video to that same technique. It is the cheapest way I can think of to do the job while retaining high quality. That old Iron Tringle: you can have it fast, good, cheap, pick any two but ONLY two. Where your personal time/labor is not a huge factor, the extra editing work saves money but keeps quality high.
