What is YouTube's Creative Commons?
YouTube uses the CC license in its published content. With this license, media content creators can allow third parties to use their work as a kind of standard content. Any YouTube user can use the Creative Commons CC By License to identify their videos.
When using the CC By License, the system automatically generates a digital signature for the video to indicate that you are using Creative Commons content and displays the source of the video with its title under the video player.
The creator can thus reserve the copyright of the video while third parties can reuse the original video but under the terms of the license.
If you find a video on YouTube with a Creative Commons license, then you do not have to edit it in various forms before it will be suitable for usage – you can upload it as it is. If there is a desire to add something or change a video, then this is not prohibited.
Quote from YouTube Help:
Based on such videos, other users can create their work in the Video Editor – including the videos used for commercial purposes.
When you add CC-licensed videos to your channel, you don’t need to specify anything else. Just put the Creative Commons License.
By posting a video under a Creative Commons license, you authorize all YouTube creators to reuse and modify it.
It’s important to look at the source of the video, which is licensed under a Creative Commons license. For example, all information from the White House web portal is distributed under a CC license (indicated at the very bottom) – any material can be taken from there.
