The iTunes Music Store is now selling videos in certain countries. The videos can only be purchased with an album and cost an extra $0.99.
For example Gorillaz' "Feel Good Inc." single now includes some short videos when purchased in the USA or Canada. The videos play directly on iTunes. Yesterday, Apple has activated a video playback feature on version 4.8 of iTunes.
Other artists such as Dave Matthews Band or Morcheeba have also videos included in their latest albums.
The resolution of the videos is either 480x360 pixels or 480x272 pixels (wide) and weight around 30MB. The videos are .mp4 files and have 16Bits, 44Khz audio quality. The videos aren't protected by any DRM technology at the moment.
