There is a lot of interesting material around on Internet. Amongst the material are many conference presentations and lectures which are interesting to listen to but which really gain very little by being filmed because the camera (usually only one) and the speaker never actually move! This makes for boring viewing, especially if the lecture is long.
When we are physically present at a lecture we (like the single camera I mentioned) are usually stationary but we can let our attention move around the room. We can at least switch between the lecturer and the slides and if things get boring we can check out all the other things in the hall!
So a good presentation switches our attention back and forth. Of course it really does help if the speaker speaks in an interesting way too! Here is an example from Videolectures.net and in this presentation you get to see the speaker, the slides, and even both at once.
Everything is Miscellaneous
This is a Google lecture (copyright Google!) so we can be fairly sure there were plenty of resources available. In a similar way the embedded TED talk below also uses a lot of resources to make sure the talk is interesting.
This talk has the added advantage that it is only 4 minutes long, and it's CC licenced!
Having written about a well filmed resource I am afraid my offering is not going to be of wonderfully high quality - but with practice I will improve, and my film is omly going to be around 4 minutes long, about the only thing it will share with the TED film!
