Readings
A blog post by Harding (2010) discusses that while the HTML5 &lt;video> tag is a big step forward for open standards, the Adobe Flash Platform will continue to play a critical role in video distribution on YouTube.

Video

 * Resolution Recommended: Original resolution of your video - for HD it is 1920x1080 (1080p) or 1280 x 720.
 * Bit rate Because bit-rate is highly dependent on codec there is no recommended or minimum value. Videos should be optimized for resolution, aspect ratio and frame rate rather than bit rate.
 * Frame rate The frame rate of the original video should be maintained without re-sampling. In particular pulldown and other frame rate re-sampling techniques are strongly discouraged.
 * Codec H.264 or MPEG-2 preferred.
 * Preferred containers FLV, MPEG-2, and MPEG-4

Audio

 * Codec MP3 or AAC preferred
 * Preferred containers FLV, MPEG-2, and MPEG-4
 * Sampling rate 44.1kHz
 * Channels 2 (stereo)
