^ [1] itag is an undocumented parameter used internally by YouTube to differentiate between quality profiles. Until December 2010, there was also a URL parameter known as fmt that allowed a user to force a profile using itag codes.

^ [2] Approximate values based on statistical data; actual bitrate can be higher or lower due to variable encoding rate.

^ [3] "At time of writing, these transcodes are encoded at a very high bitrate for decoder performance testing."

^ [4] 176x144. Videos with an aspect ratio other than 11:9 will be letterboxed/pillarboxed. (4:3 = 176x132 visible, 16:9 = 176x98 visible. In other formats, 192x144 (4:3) and 256x144 (16:9) are used instead.)

^ [5] 320x240. Videos with an aspect ratio other than 4:3 will have a lower vertical or horizontal resolution. (16:9 = 320x180. In other formats, 427x240 is used instead.)
