I'm trying to figure out what would be the best way to record a blackboard type of application in the webbrowser. Where a tutor can record a video of the blackboard with audio.
I think the obvious answer here is to make a html5 canvas and capture it at intervals as images and combine these to a video. Like so
However this has several disadvantages. It is not easy to edit the video later on. Also videos would require a lot of storage space.
What are your ideas? How can I construct this recording and playback of a blackboard?
