These are the rules for using videos on the Gundam Wiki.

• No fan made videos or Anime Music Videos are allowed.
• Use official trailers or advertisements, do not upload portions or the entirety of a Episode, Movie or OVA unless they are from official licensed sources such as http://www.youtube.com/user/GundamInfo, http://www.youtube.com/user/AnimeChannel, http://www.youtube.com/user/BandaiEntertainment
• Attempt to use English dubbed video when available, otherwise a japanese audio is acceptable if it has english closed captions. Other languages without english closed captions are not acceptable.
• Remember, you can try to request specific videos from wikia, which they can provide through their partnership with screenplay.
