Dear Experts: My goal: This summer, I would like to help a non-profit organization record (and web-cast) presentations at their annual conference. The conference will include several lectures, group discussion and coffee-house concert-like sessions. It is a non-profit and this is really a "gift" of my time (more than funds), so I need to minimize/control costs. What I have/can easily access: MacBook Air (13" i5) At least 2 other Macbooks (unknown vintage) At least one i3 Win7 box 2 TB external USB and other smaller drives (from 160 GB to 500 GB) 4-port router (with n/B/G wireless) 1 Airport Express Projector (unknown vintage) 2-channel MIDI mixer with USB into to PC and at least one nice wired mic. External (usb) MBA DVD drive Access to a wired internet connection Skype account At least 3+ iPhones (2 or more 4S and other vintages) Powered external speakers and input to sound system in the room iTunes library with lots of music I want to: Record lectures (speaker ... would be great to be able to insert PPT slides on the fly). Broadcast one or two of the lectures "live"... Would be nice to be able to "see" and maybe pick from multiple cameras on-the-fly as part of the records ("cameras" would be feeds from the iPhones -- not sure how to make this work...). Save recorded files in a format that can be easily edited/clipped later (while it would be "nice" to save multiple video feeds, I am willing to just pick one video input at the time of recording and go with it). Play tunes during gathering/breaks (using iTunes -- I know how to do this part!). I am fluent in IT/computer technology and networking, but a novice in the area of video recording and production. I expect that I will need at least one or two applications (hopefully free or lite/inexpensive options) and that I may need to set up some sort of broadcast video account beyond Skype. I have a few weeks to gather things, test out configurations, and run a few trials. Suggestions on hardware (if needed), software, web-sites/services and tutorials/guides would be greatly appreciated. Thank you. Scott B.
