Ask HN: How and where should I host a paid for video training course?

The videos will be recorded with Camtasia.

Should I record in 1280 x 1024 or 1280 x 720?

What format should I encode them in once they've been recorded?

Where can I host the videos?

How can I make the videos watchable online? I just want to be able to stick the videos somewhere and have the pages generated.

Any other advice is great, thanks.
