Listed below is an up-to-date list of file types Nunchee supports.


Nunchee supports nearly any video format for uploading. Examples are 3GP, AVI, MOV, MP4, FLV, and WMV. There are a few noteworthy formats that are not supported:

  • Quicktime (MOV) files that use the Apple Intermediate Codec (used in Final Cut Pro).
  • DRM protected files from Microsoft (WMV) or the iTunes Store (M4V, MOV).
  • WMV videos using the MSS2 video codec (for screencasting).
  • Videos generated by GoToMeeting.


If you are in control of the format (e.g. when exporting the video from your editor), we advise you to always upload videos using:

  • The MP4 container format
  • The H.264 video codec
  • The AAC audio codec
