List of YouTube features
YouTube is an online video sharing platform owned by Google, founded on February 14, 2005, by Steve Chen, Chad Hurley, and Jawed Karim, and headquartered in San Bruno, California, United States. It is the second-most visited website in the world, after Google Search.
It offers different features based on user verification, such as standard or basic features like uploading videos, creating playlists, and using YouTube Music, with limits based on daily activity (verification via phone number or channel history increases feature availability and daily usage limits); intermediate or additional features like longer videos (over 15 minutes), live streaming, custom thumbnails, and creating podcasts; advanced features like content ID appeals, embedding live streams, applying for monetization, clickable links, adding chapters, and pinning comments on videos or posts.
As of October 2024 it includes multitask with the improved miniplayer, build, share, and vote on favorite YouTube playlists, set bedtime with Sleep Timer, and an upgrade on YouTube TV.
YouTube primarily uses the VP9 and H.264/MPEG-4 AVC video codecs, and the Dynamic Adaptive Streaming over HTTP protocol. By January 2019, YouTube had begun rolling out videos in AV1 format, since then videos which are popular have it. In 2021 it was reported that the company was considering requiring AV1 in streaming hardware in order to decrease bandwidth and increase quality. For stereo, video is usually streamed alongside the Opus or AAC audio codecs. For 5.1 sound, Dolby Digital, Dolby Digital Plus, and rarely DTS Express or AAC is used. Additionally, some videos may include Eclipsa audio, which combines Opus with IAMF (Immersive Audio Model and Format). Certain music includes HE-AAC, which is exclusively available on YouTube Music. Additionally, some videos may have separate audio streams with Dynamic Range Compression.
At launch in 2005, viewing YouTube videos on a personal computer required the Adobe Flash Player plug-in to be installed in the browser. MPEG-4 Part 2 streams contained within 3GP containers were also provided for low bandwidth connections. In January 2010, YouTube launched an experimental version of the site that used the built-in multimedia capabilities of Web browsers supporting HTML video. This allowed videos to be viewed without requiring Adobe Flash Player or any other plug-in to be installed. On January 27, 2015, YouTube announced that HTML video would be the default playback method on supported browsers. HTML video streams use Dynamic Adaptive Streaming over HTTP (MPEG-DASH), an HTTP-based adaptive bit-rate streaming solution optimizes the bitrate and quality for the available network.
The platform can serve videos at optionally lower resolution levels starting at 144p for smoother playback in areas and countries with limited Internet speeds, improving compatibility, as well as for the preservation of limited cellular data plans. The resolution can be adjusted automatically based on detected connection speed or set manually.
From 2008 to 2017, users could add "annotations" to their videos, such as pop-up text messages and hyperlinks, which allowed for interactive videos. By 2019, all annotations had been removed from videos, breaking some videos that depended on the feature. YouTube introduced standardized widgets intended to replace annotations in a cross-platform manner, including "end screens" (a customizable array of thumbnails for specified videos displayed near the end of the video).
In 2018, YouTube became an International Standard Name Identifier (ISNI) registry, and announced its intention to begin creating ISNI identifiers to uniquely identify the musicians whose videos it features.
