But anyway, once you get the account, I think the only real things you would need hardware-wise would be:
1. A camcorder, DVD player or VCR to gather the clips.
2. The ability to transfer video files into the YouTube format, which I think can be done with most video software programs these days. (Plus all the proper video cords if you'll be using something other than your camcorder).
3. A fast connection and enough free hard-drive space to store at least one of the video files. The computer I usually work on is very, very, very slow, making it next to impossible to upload or download big files. But I would think a good high-speed connection would fix that.
Good luck & if you YouTube experts can think of something else, please let us know!
