>Capturing the video display from the presenter seems almost easier than having a videographer manually time static slide changes along to the video afterwards. Yes and no. For starters, it's more expensive. You need a second camera and, at worst, potentially a second operator to worry over it. Secondly, it's more error prone. Copying the VGA feed off the video switcher will fail in hilarious ways/also require a second person whose job it is to look over it. I've thrown two conferences, and been responsible for front of the house AV for a total of three and a half. You're often understaffed or overbudget, and something often gives. Even in the best of situations you end up wanting the slides as a backup. >This also assumes that people use slide decks that can't be shared afterwards (in their original glory) Post your .ppt or .key file! >can't iframe content PLEASE do not have your talk depend on conference wifi. It's impossible to guarantee stable internet with hundreds of nerds trying to slurp down hotel internet. >I'm sorry but for developer speakers and audiences, Keynote is a poor choice. I disagree. There's absolutely nothing these frameworks give you other than the warm fuzzies over the 3d transitions and that you got to style it using css. You're displaying words and pictures on a screen, and Keynote is absolutely a killer at that task.
