Attention people who know hardware and software developers ...
Here's the market -- many people now do presentations "talking to slides." The only "video" that
matters, typically, are the slides. Embedded media is sometimes used. Rarely, separate motion-video
clips are run, but usually off the same computer. In the end, all of this is projected through a
single house projection system, and the audio of the person speaking to their slides goes through a
house PA system.
The place to capture this live as at the house system. A device with a pass-through for audio and
video is ideal, because then house people don't have to hassle with more cables, splitters, etc. The
device should live between whatever switcher is feeding the projector, and between the audio mixer
and the PA amplifiers. It should record to flash media or a hard drive, and record directly to some
common web-video standard like MOV or AVI or Flash. Perhaps it can have a setting to record full
uncompressed HD, but I doubt the switcher or projector are working in that mode to begin with.
This could be accomplished in a little box no bigger than most audio flash recorders, or perhaps it
could be a box that connects to an iPad or iPhone.
Someone would make some $$$ on this if it were priced cheap and worked well.
