Many web sites include videos. Although not necessarily produced online, many video production tools allow the production of videos without actually using a physical camera. An example of this is using the YouTube video editor to create a video using pre-existing video content that is held on the platform under Creative Commons license. Video content is being used in an ever-growing range of contexts, including testimonial videos, web presenter videos, help section videos, interviews, parodies, product demonstrations, training videos, and thank you videos.
