[linux-audio-user] Creating tuition videos

Hi all, I've been thinking about writing and producing some instrumental tuition videos. I have a mini-DV firewire camcorder available. I was wondering if anyone knew of any (GPL) software I can run on Linux to create these with. I'm planning (amongst other things) to write some examples in MIDI. I'd like to generate some dynamic video footage of the notation - so a student can watch a cursor moving over the score, synchronised with the backing track audio, for example. It would also be cool to do some other things - dynamic performance notes, guitar tablature, chord shapes, add lyrics (maybe with cheesy karaoke-type word highlighting...) I'd also like to edit this together with footage of the examples being played acoustically, and explanations of what is going on. This is only an idea in the very early stages at the moment, but I'd like to know what help I could get from software... It would be nice if decent tools exist - so the hard part will be writing the material... Regards Michael
