There's no general answer to your question; each con has their own specifications for how they accept video -- video quality and audio quality specs are all determined on a con-by-con basis. If you have a specific con in mind, I would suggest looking on their website to find out how to submit and in what format.
That said, these days there aren't many (if any) cons that wouldn't accept 720p or 1080p videos, so I would send in the highest quality you can. Generally they're more concerned with making sure the quality is good enough; cons sometimes won't accept anything that's too low-res, stuff that has subtitles, etc. Doesn't sound like that'll be a problem for you, though.
