its really up to you in terms of what looks good in tradeoff for space and speed of encoding. zencoder had some settings that made its way to HN in a blog post not too long ago. theres also some settings on iocannon posts. just dig around, and they'll come up. i forget the exact formula that i use. i use presets where possible.
