A video portal (also called a video platform ) is a video-on-demand service through which users can make their videos , especially web videos , available on the World Wide Web . Usually the videos are uploaded by the creator and can then be viewed directly via streaming . Downloading videos is usually only possible via technical detours. Some video portals also allow live streaming . Video portals became popular around 2005 because of the increased bandwidth of Internet connections and are now among the most visited websites.
As the price of camcorders has decreased as technology has advanced, many individuals now own digital video recording devices. Also, digital cameras and mobile phones have built increasingly cameras that enable recording short films. Video portals are, among other things, a platform for self-publication of such short films. Since the content mainly comes from the users of these portals, it is also called user-generated content .
In addition to the self-produced content, however, many third-party videos, some of which are protected by copyright , or excerpts from them are uploaded, such as music videos , television series or individual scenes from films and series. The copyright violations are not always clearly recognizable for the user.
Many video portals have a maximum file size and length for uploaded videos, which leads to a reduction in video quality. The maximum length of videos can be avoided by dividing them into several individual films.
In addition to video portals, where users themselves upload content to the operator's server, there are now also some (regional) video portals where the operator specifies a program. The users can influence the program by making suggestions about what the operator should create reports about or about which events the operator should send a camera team to.
The requirement of making a large number of video films available to a large number of users without significant delay cannot be met with classic digital video formats . The portals therefore offer the videos in reduced resolution, depending on the user's Internet connection, and also use client software such as Flash to control the buffering and playback of moving images via streaming - this means that the playback of a video can start after a few seconds, possibly well before the complete film would be downloaded. Parts of the video that have already been played can be discarded from the cache in order to minimize memory requirements. In this case, the complete video is never available to the user; this can be seen from the fact that the web player has to download data again (and playback is thus delayed) if the video is rewound to an older point. The prerequisite is the installation of the corresponding playback program as a plug-in in the browser . On the part of the provider, in turn, appropriate server capacity, special software and a high bandwidth of the Internet connection are the prerequisites for offering streaming video to broad user groups.
The dissemination of legally questionable content poses a problem for the operators of video portals. Viacom, for example, has announced a claim for damages against Google for a billion US dollar due to copyright infringement . From a technical point of view, there is no way to prevent right-wing extremist, pornographic or violent videos from being uploaded by users, but these usually violate the usage regulations and are removed in the event of complaints. Likewise, users hardly have an opportunity to assess whether the material is protected by copyright before viewing the video, unless this is clearly visible to everyone from the preview images or the title (e.g. with current movies). Since in the meantime right-holders themselves make excerpts from their works available on video portals, it is not always clear even in the case mentioned whether it is a matter of a violation of copyrights.
Video web portals differ in terms of presentation, content and user group. Some have unique selling propositions. For video search engine optimization (video SEO) in particular, criteria such as page rank (i.e. popularity with visitors), visibility or internet portals that advertise with the analysis of web activities are used.
The only media portal that only accepts free images, audios and videos is Wikimedia Commons ; the main emphasis is on images. Videos, audio files, and other documents are also accepted but are outnumbered. The free service makes extensive efforts to remove nonfree content and thus to avoid copyright infringement as far as possible. The content of the service is limited to the contents of an educational, informierendem or illustrierendem character because it primarily as a companion project and media database on the various Wikimedia - Wikis is designed. Files of the service can be integrated directly from third-party sites or uploaded to your own website and hosted yourself , provided that the license conditions are observed.
