Thanks for the feedback :).

As to the the bitrates seem excessive, that is being explained in the next revision of the specs. I swear there is a reason!

The key is to think of what you upload to youtube as your golden master, not just a means to today's end. When a file is uploaded to YouTube, we treat it as a mezzanine file. From there, we create all of the necessary formats and bitrates for delivery to viewers on every platform and network condition. Having better quality as a mezzanine file, allows us to improve the output quality here.

Even cooler than that though, is we can use the mezzanine file to re-output new deliverable formats at a later date. Since devices and network connections keep getting better, as well as cool new codec technology like WebM, YouTube can keep your content looking fresh and up to date for years! High bitrate master files will keep you looking awesome while others dont age as well :)
