YouTube recently launched a new option that encodes some videos to both standard and high-quality parameters. The difference between standard and high-quality video is striking. Not all uploaded videos get encoded into the high-quality format, but if you follow a few simple rules, it's likely that YouTube will produce yours in both formats. I say likely because YouTube is a bit of a black box, and no one knows for sure what goes on behind the curtain. Here's what worked for me, however, and it should work for you, too.
