Photo Channel
If a user inserts an SD card into the console, or sends photos (JPEG) or videos (MJPEG) via email, they can be viewed by means of the Photo Channel. The user can create a slideshow by simply inserting an SD card with photos and, if they want to add music, MP3 or AAC files (see note regarding December 10, 2007 update to version 1.1). The Wii will automatically add Ken Burns Effect transitions between the photos and play the music in the background. A built-in editor allows users to add markings and effects to their photos. Mosaics and puzzles can also be created with this feature. Edited photos can be saved to the Wii (the Wii will not overwrite data on the SD card) and sent to other Wiis via the message board. According to the system’s manual, the following file extensions (i.e. formats) are supported: Photos (jpeg/jpg), Movies (mov/avi), and Music (mp3/aac).JPEG files can be up to 8192×8192 resolution and in baseline format. Video data contained within the .mov or .avi files must be in an OpenDML compliant MotionJPEG use some variant of this format for their videos).Photos, even high resolution ones, are compressed and decreased in resolution.An optional update to the Photo Channel became available on December 10, 2007. It allows customization of the Wii Menu by letting users replace the Photo Channel icon with a picture taken from an SD card or a picture from the Wii Message Board. It also allows playback of songs in random order. MP3 support is replaced with AAC.Wii games that feature playback of MP3 files will continue to support the MP3 format, but will not be able to play AAC files. The update also added support for MPEG-4 encoded files in the .m4a extension. The new update also allows a person to assign his or her favorite picture as the main screen for the Photo Channel.Wii owners who updated to version 1.1 can revert to version 1.0 by deleting it from the Channels menu in the Data Management setup. Consoles released after December 10 will come with the version 1.1 update preinstalled, and cannot be “downgraded” to version 1.0.
