My article The Moving Picture: Decoding YouTube Upload Options just posted on www.eventdv.net. It explores the options available when uploading original SD video to YouTube, detailing my conclusions after uploading six files ranging in resolution from 480x270 to 720p.

Here are links to the six files. I concluded that 720p produced the best results (I upscaled in Final Cut Pro); see what you think. By the way, that's the fabulous Stevie Barr on banjo, shot at GrahamFest 2009.
