Adam Buxton knows a lot about the media and music. I keep an eye on his blog and I can only urge you to do the same! For example, did you know about the fabulous screen writing software Moviemaker? Do have a look; it's really funny.
Adam Buxton also hosts the regular BUG gigs where artists come to talk about making music videos among other things. Get some tickets and go see the next BUG show. Below is a link to the BFI website with a clip from BUG 17 where Buxton interviews some video directors about their "crowd sourcing" technique for their latest video.
You can also check out the BUG site's archives to see some unusual and low budget music videos.
