Problems playing the file?

Wikimedia accepts and encourages uploading video files on Commons. Videos, like images, must be freely licensed. The preferred video format is WebM but the ogv container is also allowed. For help on converting to a preferred format, go to Help:Converting video.

There is a dedicated discussion and support mailing list for makers of video in Wikimedia projects, WikiVideo-l (Archive). You can also join the WMF Multimedia Team mailing list.

Importance of video[edit]

There are roughly 52,000 video files on Commons.

Good examples of videos:

  • Nature videos, such as a recording of a scenic view or a hurricane (ex. #1)
  • Wildlife videos, such as the behavior of animals (ex. #1)
  • Sports videos, such as demonstrating a particular rule or method of playing (ex. #1)
  • Cultural videos, such as a traditional or contemporary dance (ex. #1)
  • Architectural videos, such as kinetic building elements (ex. #1)
  • Science videos, such as chemistry experiments (ex. #1)
  • Demonstrations of tools, showing how they work. (ex. #1)
  • Visualization of 3D data where one of dimensions is shown as time (ex. #1 & #2)
  • Historical videos (ex. #1 & #2)

Related WikiProjects[edit]

There are and have been several WikiProjects aiming at the use and production of videos in Wikipedia and Wikimedia projects, for instance WikiProject Wiki Makes Video and WikiTV. See also the List of Wiki video projects.

Video formats[edit]

Wikimedia uses Ogg Theora and WebM for video because they are open and royalty-free, unlike other video formats such as Apple's QuickTime (mov) and Microsoft's WMV, which contain patents and require royalties.

Uploading a video[edit]

The process of uploading a video is similar to uploading an image.

  1. First ensure the video is freely licensed and within scope.
  2. Firefox users are encouraged to install the Firefogg-Addon and use the UploadWizard to upload video. UploadWizard will then automatically convert the video file to highest quality using Firefogg (if necessary) and users do not have to fiddle with conversion parameters.
  1. (Otherwise:)
  2. Convert the video to the Theora or the WebM format, if it is not already in one of those formats.
  3. Go to the Upload page and fill out each field. Include appropriate topic categories. It will take several minutes to upload. Uploads of files larger than the maximum file size of 100 Mb are possible with help of a user with server access. See Help:Server-side upload. Alternatively you could make use of the chunked upload feature, which allows uploads up to 1000 Mb in size. Theoretically it is also possible to split the video into shorter parts and upload each part separately. The template {{Split file}} could be used to link the parts of files split in this way.

Video usage[edit]

Embedding Video[edit]

Creating a link that appears at first as a still image of a video and that plays the video after its play button is clicked is called “embedding a video”. The easiest way to embed a video directly into an article (or another page) is by using the same [[File:]] syntax as for image or sound files. The result is on the right. The video can be resized by adding a fixed size (like "|200px") or - preferable - the "|upright" parameter. In most cases you should stick to the default size. If it is higher than wide, use the pure "|upright".

[[File:Time Lapse of New York City.ogv|thumb |200px |New York City Time Lapse]]
[[File:Time Lapse of New York City.ogv|thumb |upright |New York City Time Lapse]]
[[File:Time Lapse of New York City.ogv|thumb |upright=2 |New York City Time Lapse]]

Setting a video thumbnail image[edit]

In case of Ogg Theora files, a keyframe from the midpoint of the video is used by default for the initial thumbnail image. To use a different keyframe, use the thumbtime parameter. For instance:

[[File:Time Lapse of New York City.ogv |thumbtime=12 |thumb |200px |New York City timelapse]]

Either specify the time in seconds or use colons to separate hours, minutes and seconds. Separate a fraction of a second by a "." (dot). Only tenths (0.1, 0.2, etc.) of seconds work, currently.

Default still image
Still image at 12 seconds
Default still image
Still image at 7.8 seconds

There are two types of links to a video:

  • File – To create a link to the video's File Description Page,
    • use [[:File:Time Lapse of New York City.ogv]].
    • To make the text of a link to the video's File Description Page appear as some text other than the video's filename, use [[:File:Time Lapse of New York City.ogv|some text you prefer]].
  • Media – To create a link that downloads the video,
    • use [[Media:Time Lapse of New York City.ogv]] or use [[:Media:Time Lapse of New York City.ogv]].
    • To make the text of a link that downloads the video appear as some text other than the video's filename, use [[Media:Time Lapse of New York City.ogv|some text you prefer]] or use [[:Media:Time Lapse of New York City.ogv|some text you prefer]].

Temporal media fragments[edit]

Starts at 5 seconds and ends playback at 7 seconds

Allows embed code to reference a segment of the video stream or set a start time. Hover over the player to see start time listed as 5s, press play and notice it stops playback at 7 seconds.

[[File:Weeding.ogv|thumb|300px|start=5|end=7|Starts at 5 seconds and ends playback at 7 seconds]]

Looped animation[edit]

Example of GIF animation.

In case of animated GIF files, the animation is played continuously in a loop. Animated GIFs are (currently) scaled down on server-side to the required thumb size if they do not exceed the 12.5 Megapixel limit. If they exceed it a still frame will be displayed.

Subtitles and closed captioning[edit]

How to create subtitles.
Main article: Commons:Timed Text

To upload an already created subtitle file, open the file on your computer in a text editor (such as Notepad) and copy the text into a new page in the TimedText namespace that matches the filename of the video and the language code.

Keep in mind to paraphrase not spoken sounds and encompass them with rounded brackets. E.g.

 1
 00:00:20,000 --> 00:00:24,400
 (engine sound)

Playing videos[edit]

See also: Commons:Media help

Playing video and sound embedded on Wikimedia sites requires no additional software. The web browsers Mozilla Firefox[1]and Google Chrome[2] are able to play these file formats without additional software. Safari users may install XiphQT for native playback.

You must install software to play video that you have downloaded to your computer. You can learn at Commons:Media help what software you need to play our media files. VLC multimedia player[3] is one that is open-source and multi-platform.

Videos and copyright[edit]

Main article: Commons:Licensing

In addition to checking for video copyright, the audio must not contain copyrighted sounds. This includes any copyrighted songs that were added to the video. Ask questions regarding the copyright of the video at the Village pump.

Examples of videos that would not be allowed due to copyright:

  • Screen captures of software that is itself not under a free license. This includes the Mac OS and Windows operating system. However, screen captures of software under the GPL or a similar free software license are generally considered to be OK.
  • TV/DVD/Videogame/Music video clips and recordings, unless their copyright has expired.
  • Copyrighted symbols, logos, etc. (Not to be confused with trademarks.)
  • Models, masks, toys, and other objects which represent a copyrighted work, such as a cartoon or movie character. See Commons:Derivative works.
  • Video that contains copyrighted music. Remove the audio from the video and then upload.
  • Videos of a presentation or lecture, unless the person(s) making the presentation has/have granted explicit permission to allow a video of their performance to be published under a Commons-compatible license via COM:OTRS.

Examples of videos that would be OK to upload:

  • Nature videos (video taken at a National Park or of a bird in your backyard)
  • Videos from the United States government, such as from NASA.
