Best Software For Putting Lectures Online? 126
An anonymous reader writes "I'm trying to help a school put their classes online in the way most minimally invasive to the teachers. A few environmental considerations: They don't always have live internet in the classroom, or I'd just run to Skype. I'm hoping to make it as much one-touch start/stop as possible to start recording, stop recording, and upload to a server. I'd like to believe others here have already done something similar, so if a package or process worked for you, that would be great to hear. Not sure what if it's all PowerPoint lectures, or if they actually use a whiteboard, and if so what the best camera would be to use (on a school budget!)."

Additionally, it has a codec called Windows Media Screen which uses compression well suited to static computer images. You can get a whole hour long lecture in like 30MB if space is a concern.
You just have the instructor wear a mic that feeds in to the computer's input (if the room has sound reinforcement just split off a feed from that) and students get all their slides and what they were saying while they did it. Means they can run programs too and demo that.
For easiest results, record in regular Windows Media format, which takes up way more space, but you can upload that right to Youtube. If you let them know what you are doing they'll let you have longer videos.
In terms of recording whiteboards and so on, I don't know of anything both easy and cheap. An AVCHD cam does a great job, but you usually need to spend a little time in a video editor afterwards.

What has worked for me is to set up a pair of HD cameras in the back of the room, pointed so each can see (part of) the blackboard. Then I post-process this into a single video stream later.

You can limit access to video by username/password and/or by IP address.
