It appears that Blackboard Collaborate can save a recording of a blackboard session for later download and replay. However, playing it back in the Java client supplied isn't very nice (i.e. pretty limited). So I'm looking for a way to convert it into a regular video file and play it with a video player.
Where can I learn about the format of that "recording" file? Is it proprietary or open? Is it possible to extract the audio track and the slides from it? I tried looking at it, but "file" just reports "data", so it doesn't have any of the well-known headers. It doesn't seem compressed or encrypted though, as there's a lot of plaintext strings at the beginning.
Also, I'd be interested to hear if you have any tips for improving audio quality.
