Shortcuts

YouTubeは、世界最大級の動画共有サービスである（Wikipediaの記事を参照）。多くのYouTube上の動画がコモンズにアップロードされている（Category:YouTubeを参照）が、ほとんどのYouTube動画はここにアップロードするのに適格ではない。

ライセンス

ほとんどのYouTube動画はウィキメディア・コモンズへのアップロードの対象外です。なぜなら、それらはまだ著作権があり、標準の YouTube ライセンスでのみ提供されているからです。

しかし、YouTubeは、投稿者に Commons に互換性のある Creative Commons Attribution 3.0 (CC BY) の免許下での動画をライセンスする [1] を提供している。

Under Commons policies, these videos may be transferred to Wikimedia Commons, with the usual caution that you should not upload work that appears to be plagiarized or is out of scope.

Be also aware of YouTube's terms of service.

Some other videos don't use this license option, but include it:

in the video description (e.g. Wikipedia: Username, eligible for Commons and already here), or,
directly in the video (e.g. Blu - Muto, though this one is not eligible for Commons as CC BY-NC-ND).

Uploaded videos should be tagged with {{YoutubeReview}} to request a license review to permanently document that the video really was available under that license.

If they are released under CC BY 3.0, you can add the license template {{YouTube CC-BY}}.

Additionally, you can use {{From YouTube}} to format the source information.

Search videos licensed as Creative Commons on YouTube by doing a search there.

Then a filter menu will show up with one of the choices being "Creative Commons".

You can also use Vera's Tool to find all open-licenced videos in a given YouTube channel.

Screenshots are similarly handled.

That is, screenshots might be acceptable only if the videos are freely licensed or in the public domain.

Downloading videos from YouTube

For advanced options, see Commons:YouTube files/Downloading.

Uploading videos from YouTube

Upload using video2commons

This easy tool to directly upload videos from source is helpful: video2commons.

Please check if the video has a free license before uploading.

A Wikimedia account is required.

Upload manually

To upload videos from YouTube with the Upload Wizard or alternative upload forms, first download the video in the appropriate format or convert it to an appropriate format (webm is recommended) and then upload it like any other file.

Changing the licence

To change the licence of your own videos on YouTube, so you can use the above tool to copy them to Commons, use this process (valid as of November 2020) on a desktop machine:

go to your YouTube channel
click the profile icon, top-right
select "YouTube Studio"
select "Content" (in left-hand column)
select one or more videos
select "Edit" on the toolbar
select "License"
use the drop-down to change the license to "Creative Commons - Attribution"
select "Update videos", on the toolbar
accept

You can also change the default license for new uploads to YouTube:

go to your YouTube channel
click the profile icon, top-right
select "YouTube Studio"
select "Settings" (on the left nav bar)
select "Upload defaults"
choose "Advanced settings" tab
change "License" to "Creative Commons - Attribution"
SAVE

Using Commons videos and images in your YouTube videos

In the opposite case, if you want to reuse a Commons video or image as part of your new YouTube video, you must:

Attribute that portion to the authors of the content you reuse, per Commons:Reusing content outside Wikimedia, in both the video itself and the text description, with the a link to all original Commons pages and all authors' names (see the history tab of the Commons page).
License your video appropriately for the licenses of the works being used.
