At this point I'm thinking I should just give up on the Youtube-upload-without-a-computer requirement and just settle for the best HD camcorder I can afford.
Anyone got any recommendations for an HD camcorder that a) takes SDXC cards b) costs less than £300 and c) records really well in 1080p, for up to, say, 2 hours?
I haven't looked at any camcorders recently...
I'd also suggest for that length of recoding to get something that can take bigger batteries, or make sure you can have it powered from an AC outlet on location. Allot of them now have separate chargers and don't have a DC in.
Other considerations: mic inputs? Will you be able to get an audio feed from the conference, or will you be on your own. Even if you can't get a soundboard feed a mic input so you can attach a shotgun will be nice to have.
