This page explains how to create Ogg Theora and Vorbis files. If you need help playing them, see Wikinfo:Media help.

Images, audio, and video files must be uploaded into Wikinfo using the "Upload file" link on the left-hand navigation bar. Only logged in users can upload files. Once a file is uploaded, other pages can include or link to the file. Uploaded files are given the Image: prefix by the system, even if they are not images, and each one has an image description page. Please consider uploading freely licensed content to the Wikimedia Commons instead of here. The maximum size of an uploaded file is 20 megabytes.

Special characters and math

It is not necessary to upload images to use special characters or but it is for complex mathematical expressions.

Wikipedia uses a UTF-8 encoding scheme, which means that any Unicode character can and should be entered directly. See Help:Special characters for details and help.

The TeX markup used on Wikipedia for mathematical formulas does not work on Wikinfo. For help and instructions, see Help:Formula. To capture an image of a math function find a site that does render math images, insert the coding, and then save and upload the image. So long as you do not save the edit any Wikipedia page will serve (use the tab "show preview"). Or use http://www.mathtran.org/index.html

Some math notes

Text files

Please do not upload plain text (.txt), Microsoft Word (.doc), or text files in other formats. Instead, please start a new page and input the text using standard wiki formatting. Please do not dump text into Wikinfo unless you wrote it yourself, or you know that it meets our copyright licensing requirements. If you do not have time to format it yourself, add the {{wikify}} tag at the top of the page.

Images

Images can be displayed directly on Wikipedia pages.

The preferred formats are JPEG and PNG. [[GIF}} is acceptable. SVG, despite its frequent use on Wikipedia, should always be converted to .png before uploading (many browsers do that automatically when viewing or saving .svg images).

Video

Wikipedia uses Ogg Theora for video because it is open and patent-free. That is not required by Wikinfo provided viewing the video can be accomplished without purchasing special software. In other words, the .m4v and .mov formats used by iTunes and Quicktime are acceptable. This might not be acceptable if the images are copied and used commercially.

Because most popular movie/audio formats are patented and require a royalty, there are no free all purpose video converters.

Theora video conversion help page

Useful software:

  • For video, ffmpeg2theora [1] is a command line encoder capable of converting numerous file formats (.mov, .mpg, .mpeg, .avi) into Ogg Theora. It works on Windows, Macintosh, and Linux/Unix. (For information on how to use ffmpeg2theora,.)
  • You can also use the encoder_example application included with libtheora in combination with a program like MPlayer [2] that is capable of dumping raw (yuv4mpeg) video and sound to encode in Ogg Theora
  • LiVES and Cinelerra are video editing programs for Linux which are able to edit Ogg Theora videos

Audio

Wikipedia uses Ogg Vorbis for sound. The Ogg Vorbis format is not encumbered by patents, and has been found to offer higher audio fidelity than the MP3 format. It is competitive even at low bitrates for encoding speech, comparable with even HE-AAC. A decision has been made that MP3 files will not be hosted at Wikipedia. This restriction does not apply on Wikinfo.

Software supporting Vorbis exists for many platforms. Winamp multimedia player can be used to play Ogg Vorbis files. Although Apple iTunes does not natively support Vorbis, Xiph.org provides a QuickTime component which can be used in iTunes and QuickTime on both Windows and Mac OS. On Microsoft Windows, DirectShow filters exist to decode Vorbis in multimedia players like Windows Media Player and others which support DirectShow.

Useful software for audio:

  • For audio editing, Audacity is a high quality free audio recorder/editor for Windows, Macintosh, and Linux/Unix.
  • Sweep is another free audio editor which can be used in Linux environments.
  • For encoding to Ogg Vorbis, it is recommended that you use the Hydrogenaudio-recommended encoder version for best results. oggenc (cross-platform) is the command-line encoder, while OggDropXPd (Win32-only) is an easy-to-use GUI for encoding to Ogg Vorbis.
  • dBpowerAMP Music Converter offers a convenient GUI for transcoding between most audio codecs, including Ogg Vorbis. The Vorbis encoder must be downloaded separately from the software, but it is freely available from the same website.
  • The easiest way to play ogg vorbis files on legacy Macintoshes (OS 9 and lower) is to use JustOgg.

The VorbisSoftwarePlayers node at the xiph.org wiki has an up-to-date list of Vorbis-supporting software for all operating systems. Users can test these players using the list of Vorbis audio streams available at [3].

Actual insertion of audio content into page

Most viable is to use Template:Listen, see its page for detailed description, common usage is listed here:

Usage

{{Listen|filename=Name of file.ogg|title=Title of this file|description=The description of this file|format=[[Ogg]]}}

Example:

{{Listen|filename=Accordian chords-01.ogg|title=Accordion chords|description=Chords being played on an accordion — 145 KB|format=[[Ogg]]}}

gives this:

Accordion chords

File:Accordian chords-01.ogg

Chords being played on an accordion — 145 KB
