Youtube because i love you awesome so my wife yes i do i got this my dream come true future please me okay sex yes please?

progressive scanning. YouTube's statistics shows that interlaced videos are still being uploaded to YouTube, and there is no sign of that dwindling. YouTube attributes this to uploading of made-for-TV content. Quality and formats YouTube originally offered videos at only one quality level, displayed at a resolution of 320×240 pixels using the Sorenson Spark codec (a variant of H.263), with mono MP3 audio. In June 2007, YouTube added an option to watch videos in 3GP format on mobile phones. In March 2008, a high-quality mode was added, which increased the resolution to 480×360 pixels. In December 2008, 720p HD support was added. At the time of the 720p launch, the YouTube player was changed from a 4:3 aspect ratio to a widescreen 16:9. With this new feature, YouTube began a switchover to H.264/MPEG-4 AVC as its default video compression format. In November 2009, 1080p HD support was added. In July 2010, YouTube announced that it had launched a range of videos in 4K format, which allows a resolution of up to 4096×3072 pixels. In March 2015, support for 4K resolution was added, with the videos playing at 3840 × 2160 pixels. In June 2015, support for 8K resolution was added, with the videos playing at 7680×4320 pixels. In November 2016, support for HDR video was added which can be encoded with Hybrid Log-Gamma (HLG) or Perceptual Quantizer (PQ). HDR video can be encoded with the Rec. 2020 color space.In June 2014, YouTube began to deploy support for high frame rate videos up to 60 frames per second (as opposed to 30 before), becoming available for user uploads in October. YouTube stated that this would enhance "motion-intensive" videos, such as video game footage.YouTube videos are available in a range of quality levels. The former names of standard quality (SQ), high quality (HQ), and high definition (HD) have been replaced by numerical values representing the vertical resolution of the video. The default video stream is encoded in the VP9 format with stereo Opus audio; if VP9/WebM is not supported in the browser/device or the browser's user agent reports Windows XP, then H.264/MPEG-4 AVC video with stereo AAC audio is used instead. 2020 picture quality cut On March 18, 2020, Thierry Breton, a European commissioner in charge of digital policy of the European Union urged streaming services including YouTube to limit their services. The request came as a result of the prevention of Europe's broadband networks from crashing as tens of millions of people started telecommuting, due to the COVID-19 pandemic in Europe. According to the EU, the streaming platforms should consider offering only standard definition, rather than high-definition, programs and users should be responsible for their data consumption. On March 20, YouTube responded by temporarily downgrading the videos in standard definition across the EU including the traffic in the UK as well. Annotations From 2008 to 2017, users could add "annotations" to their videos—such as pop-up text messages and hyperlinks. These functions were notably used as the basis for interactive videos, which used hyperlinks to other videos to achieve branching elements. In March 2017, it was announced that the annotations editor had been discontinued and the feature would be sunset because their use had fallen rapidly, users had found them to be an annoyance, and because they were incompatible with mobile versions of the service. Annotations were removed entirely from all videos on January 15, 2019. YouTube had 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) and "cards", but they are not backwards compatible with existing annotations, while the removal of annotations will also break all interactive experiences which depended on them. Live streaming YouTube carried out early experiments with live streaming, including a concert by U2 in 2009, and a question-and-answer session with US President Barack Obama in February 2010. These tests had relied on technology from 3rd-party partners, but in September 2010, YouTube began testing its own live streaming infrastructure. In April 2011, YouTube announced the rollout of YouTube Live, with a portal page at the URL "www.youtube.com/live". The creation of live streams was initially limited to select partners. It was used for real-time broadcasting of events such as the 2012 Olympics in London. In October 2012, more than 8 million people watched Felix Baumgartner's jump from the edge of space as a live stream on YouTube.In May 2013, creation of live streams was opened to verified users with at least 1,000 subscribers; in August of that year the number was reduced to 100 subscribers, and in December the limit was removed. In February 2017, live streaming was introduced to the official YouTube mobile app. Live streaming via mobile was initially restricted to users with at least 10,000 subscribers, but as of mid-2017 it has been reduced to 100 subscribers. Live streams can be up to 4K resolution at 60 fps, and also support 360° video. In February 2017, a live streaming feature called Super Chat was introduced, which allows viewers to donate between $1 and $500 to have their comment highlighted. 3D videos In a video posted on July 21, 2009, YouTube software engineer Peter Bradshaw announced that YouTube users could now upload 3D videos. The videos can be viewed in several different ways, including the common anaglyph (cyan/red lens) method which utilizes glasses worn by the viewer to achieve the 3D effect. The YouTube Flash player can display stereoscopic content interleaved in rows, columns or a checkerboard pattern, side-by-side or anaglyph using a red/cyan, green/magenta or blue/yellow combination. In May 2011, an HTML5 version of the YouTube player began supporting side-by-side 3D footage that is compatible with Nvidia 3D Vision. The feature set has since been reduced, and the 3D feature currently only supports red/cyan anaglyph with no side-by-side support. 360-degree videos In January 2015, Google announced that 360-degree video would be natively supported on YouTube. On March 13, 2015, YouTube enabled 360° videos which can be viewed from Google Cardboard, a virtual reality system. YouTube 360 can also be viewed from all other virtual reality headsets. Live streaming of 360° video at up to 4K resolution is also supported.In 2017, YouTube began to promote an alternative stereoscopic video format known as VR180, which is limited to a 180-degree field of view but is promoted as being easier to produce than 360-degree video and allowing more depth to be maintained by not subjecting the video to equirectangular projection. Community On September 13, 2016, YouTube launched a public beta of Community, a social media-based feature that allows users to post text, images (including GIFs), live videos and others in a separate "Community" tab on their channel. Prior to the release, several creators had been consulted to suggest tools Community could incorporate that they would find useful; these YouTubers included Vlogbrothers, AsapScience, Lilly Singh, The Game Theorists, Karmin, The Key of Awesome, The Kloons, Peter Hollens, Rosianna Halse Rojas, Sam Tsui, Threadbanger and Vsauce3.After the feature has been officially released, the community post feature gets activated automatically for every channel that passes a specific threshold of subscriber counts or already has more subscribers. This threshold was lowered over time, from 10000 subscribers to 1500 subscribers, to 1000 subscribers, which is the current threshold as of September 2019.Channels that the community tab becomes enabled for, get their channel discussions (the name before March 2013 “One channel layout” redesign finalization: “channel comments”) permanently erased, instead of co-existing or migrating. YouTube offers users the ability to view its videos on web pages outside their website. Each YouTube video is accompanied by a piece of HTML that can be used to embed it on any page on the Web. This functionality is often used to embed YouTube videos in social networking pages and blogs. Users wishing to post a video discussing, inspired by, or related to another user's video can make a "video response". On August 27, 2013, YouTube announced that it would remove video responses for being an underused feature. Embedding, rating, commenting and response posting can be disabled by the video owner. YouTube does not usually offer a download link for its videos, and intends for them to be viewed through its website interface. A small number of videos can be downloaded as MP4 files. Numerous third-party web sites, applications and browser plug-ins allow users to download YouTube videos.In February 2009, YouTube announced a test service, allowing some partners to offer video downloads for free or for a fee paid through Google Checkout. In June 2012, Google sent cease and desist letters threatening legal action against several websites offering online download and conversion of YouTube videos. In response, Zamzar removed the ability to download YouTube videos from its site. Users retain copyright of their own work under the default Standard YouTube License, but have the option to grant certain usage rights under any public copyright license they choose. Since July 2012, it has been possible to select a Creative Commons attribution license as the default, allowing other users to reuse and remix the material. Platforms Most modern smartphones are capable of accessing YouTube videos, either within an application or through an optimized website. YouTube Mobile was launched in June 2007, using RTSP streaming for the video. Not all of YouTube's videos are available on the mobile version of the site.Since June 2007, YouTube's videos have been available for viewing on a range of Apple products. This required YouTube's content to be transcoded into Apple's preferred video standard, H.264, a process that took several months. YouTube videos can be viewed on devices including Apple TV, iPod Touch and the iPhone.In July 2010, the mobile version of the site was relaunched based on HTML5, avoiding the need to use Adobe Flash Player and optimized for use with touch screen controls. The mobile version is also available as an app for the Android platform.In September 2012, YouTube launched its first app for the iPhone, following the decision to drop YouTube as one of the preloaded apps in the iPhone 5 and iOS 6 operating system. According to GlobalWebIndex, YouTube was used by 35% of smartphone users between April and June 2013, making it the third-most used app.A TiVo service update in July 2008 allowed the system to search and play YouTube videos.In January 2009, YouTube launched "YouTube for TV", a version of the website tailored for set-top boxes and other TV-based media devices with web browsers, initially allowing its videos to be viewed on the PlayStation 3 and Wii video game consoles.In June 2009, YouTube XL was introduced, which has a simplified interface designed for viewing on a standard television screen. YouTube is also available as an app on Xbox Live.On November 15, 2012, Google launched an official app for the Wii, allowing users to watch YouTube videos from the Wii channel. An app was available for Wii U and Nintendo 3DS, but was discontinued in August 2019. Videos can also be viewed on the Wii U Internet Browser using HTML5. Google made YouTube available on the Roku player on December 17, 2013, and, in October 2014, the Sony PlayStation 4.In November 2018, YouTube launched as a downloadable app for the Nintendo Switch. On June 19, 2007, Google CEO Eric Schmidt appeared to Paris to launch the new localization system. The interface of the website is available with localized versions in 104 countries, one territory (Hong Kong) and a worldwide version. The YouTube interface suggests which local version should be chosen based on the IP address of the user. In some cases, the message "This video is not available in your country" may appear because of copyright restrictions or inappropriate content. The interface of the YouTube website is available in 76 language versions, including Amharic, Albanian, Armenian, Burmese, Khmer, Kyrgyz, Laotian, Mongolian, Persian and Uzbek, which do not have local channel versions. Access to YouTube was blocked in Turkey between 2008 and 2010, following controversy over the posting of videos deemed insulting to Mustafa Kemal Atatürk and some material offensive to Muslims. In October 2012, a local version of YouTube was launched in Turkey, with the domain youtube.com.tr. The local version is subject to the content regulations found in Turkish law. In March 2009, a dispute between YouTube and the British royalty collection agency PRS for Music led to premium music videos being blocked for YouTube users in the United Kingdom. The removal of videos posted by the major record companies occurred after failure to reach an agreement on a licensing deal. The dispute was resolved in September 2009. In April 2009, a similar dispute led to the removal of premium music videos for users in Germany. YouTube Premium (formerly YouTube Red) is YouTube's premium subscription service. It offers advertising-free streaming, access to exclusive content, background and offline video playback on mobile devices, and access to the Google Play Music "All Access" service. YouTube Premium was originally announced on November 12, 2014, as "Music Key", a subscription music streaming service, and was intended to integrate with and replace the existing Google Play Music "All Access" service. On October 28, 2015, the service was relaunched as YouTube Red, offering ad-free streaming of all videos, as well as access to exclusive original content. As of November 2016, the service has 1.5 million subscribers, with a further million on a free-trial basis. As of June 2017, the first season of YouTube Originals had gotten 250 million views in total.In May 2014, before Music Key service was launched, the independent music trade organization Worldwide Independent Network alleged that YouTube was using non-negotiable contracts with independent labels that were "undervalued" in comparison to other streaming services and that YouTube would block all music content from labels who do not reach a deal to be included on the paid service. In a statement to the Financial Times in June 2014, Robert Kyncl confirmed that YouTube would block the content of labels who do not negotiate deals to be included in the paid service "to ensure that all content on the platform is governed by its new contractual terms." Stating that 90% of labels had reached deals, he went on to say that "while we wish that we had [a] 100% success rate


How to Get Youtube Views Up Quick?

Unofficial uploads of the skit to YouTube drew in more than five million collective views by February 2006 before they were removed at request of NBC-Universal about two months later, raising questions of copyright related to viral content. Despite eventually being taken down, these duplicate uploads of the skit helped popularize YouTube's reach and led to the upload of further third-party content. The site grew rapidly and, in July 2006, the company announced that more than 65,000 new videos were being uploaded every day, and that the site was receiving 100 million video views per day.The choice of the name www.youtube.com led to problems for a similarly named website, www.utube.com. The site's owner, Universal Tube & Rollform Equipment, filed a lawsuit against YouTube in November 2006 after being regularly overloaded by people looking for YouTube. Universal Tube has since changed the name of its website to www.utubeonline.com. On October 9, 2006, Google announced that it had acquired YouTube for $1.65 billion in Google stock. The deal was finalized on November 13, 2006. Google's acquisition launched new newfound interest in video-sharing sites; IAC, which now owned Vimeo after acquiring CollegeHumor, used its asset to develop a competing site to YouTube, focusing on supporting the content creator to distinguish itself from YouTube. In March 2010, YouTube began free streaming of certain content, including 60 cricket matches of the Indian Premier League. According to YouTube, this was the first worldwide free online broadcast of a major sporting event. On March 31, 2010, the YouTube website launched a new design, with the aim of simplifying the interface and increasing the time users spend on the site. In May 2010, YouTube videos were watched more than two billion times per day. This increased to three billion in May 2011, and four billion in January 2012. In February 2017, one billion hours of YouTube were watched every day.According to data published by market research company comScore, YouTube is the dominant provider of online video in the United States, with a market share of around 43% and more than 14 billion views of videos in May 2010.In October 2010, Hurley announced that he would be stepping down as chief executive officer of YouTube to take an advisory role, and that Salar Kamangar would take over as head of the company. In April 2011, James Zern, a YouTube software engineer, revealed that 30% of videos accounted for 99% of views on the site. In November 2011, the Google+ social networking site was integrated directly with YouTube and the Chrome web browser, allowing YouTube videos to be viewed from within the Google+ interface.In May 2011, 48 hours of new videos were uploaded to the site every minute, which increased to 60 hours every minute in January 2012, 100 hours every minute in May 2013, 300 hours every minute in November 2014, and 400 hours every minute in February 2017. As of January 2012, the site had 800 million unique users a month. It has been claimed, by The Daily Telegraph in 2008, that in 2007, YouTube consumed as much bandwidth as the entire Internet in 2000. According to third-party web analytics providers, Alexa and SimilarWeb, YouTube is the second-most visited website in the world, as of December 2016; SimilarWeb also lists YouTube as the top TV and video website globally, attracting more than 15 billion visitors per month. In October 2006, YouTube moved to a new office in San Bruno, California. In December 2011, YouTube launched a new version of the site interface, with the video channels displayed in a central column on the home page, similar to the news feeds of social networking sites. At the same time, a new version of the YouTube logo was introduced with a darker shade of red, the first change in design since October 2006.In early March 2013, YouTube finalized the transition for all channels to the previously optional "One Channel Layout," which removed many customization options and custom background images for consistency, and split up the channel information to different tabs (Home/Feed, Videos Playlists, Discussion, About) rather than one unified page. In May 2013, YouTube launched a pilot program for content providers to offer premium, subscription-based channels within the platform. In February 2014, Susan Wojcicki was appointed CEO of YouTube. In November 2014, YouTube announced a subscription service known as "Music Key," which bundled ad-free streaming of music content on YouTube with the existing Google Play Music service.In February 2015, YouTube released a secondary mobile app known as YouTube Kids. The app is designed to provide an experience optimized for children. It features a simplified user interface, curated selections of channels featuring age-appropriate content, and parental control features. Later on August 26, 2015, YouTube launched YouTube Gaming—a video gaming-oriented vertical and app for videos and live streaming, intended to compete with the Amazon.com-owned Twitch.In October 2015, YouTube announced YouTube Red (now YouTube Premium), a new premium service that would offer ad-free access to all content on the platform (succeeding the Music Key service released the previous year), premium original series, and films produced by YouTube personalities, as well as background playback of content on mobile devices. YouTube also released YouTube Music, a third app oriented towards streaming and discovering the music content hosted on the YouTube platform.In January 2016, YouTube expanded its headquarters in San Bruno by purchasing an office park for $215 million. The complex has 51,468 square metres (554,000 square feet) of space and can house up to 2,800 employees. On August 29, 2017, YouTube officially launched the "polymer" redesign of its user interfaces based on Material Design language as its default, as well a redesigned logo that is built around the service's play button emblem.On April 3, 2018, a shooting took place at YouTube's headquarters in San Bruno, California.On May 17, 2018, YouTube announced the re-branding of YouTube Red as YouTube Premium (accompanied by a major expansion of the service into Canada and 13 European markets), as well as the upcoming launch of a separate YouTube Music subscription.In September 2018, YouTube began to phase out the separate YouTube Gaming website and app and introduced a new Gaming portal within the main service. YouTube staff argued that the separate platform was causing confusion and that the integration would allow the features developed for the service (including game-based portals and enhanced discoverability of gaming-related videos and live streaming) to reach a broader audience through the main YouTube website.In July 2019, It was announced that YouTube will discontinue support for Nintendo 3DS systems on September 3, 2019. However, owners of New Nintendo 3DS, or New Nintendo 3DS XL, can still access YouTube on the Internet browser.In November 2019, it was announced that YouTube was gradually phasing out the classic version of its Creator Studio across all users by the spring of 2020. As of August 2020, the classic studio is no longer available.During the COVID-19 pandemic, when most of the world was under stay-at-home orders, usage of services such as YouTube grew greatly. In response to EU officials requesting that such services reduce bandwidth as to make sure medical entities had sufficient bandwidth to share information, YouTube along with Netflix stated they would reduce streaming quality for at least thirty days as to cut bandwidth use of their services by 25% to comply with the EU's request. YouTube later announced that they will continue with this move worldwide, "We continue to work closely with governments and network operators around the globe to do our part to minimize stress on the system during this unprecedented situation".In June 2020, the ability to use categories was phased out. YouTube primarily uses the VP9 and H.264/MPEG-4 AVC video formats, and the Dynamic Adaptive Streaming over HTTP protocol. By January 2019, YouTube had begun rolling out videos in AV1 format. Playback Previously, viewing YouTube videos on a personal computer required the Adobe Flash Player plug-in to be installed in the browser. In January 2010, YouTube launched an experimental version of the site that used the built-in multimedia capabilities of web browsers supporting the HTML5 standard. This allowed videos to be viewed without requiring Adobe Flash Player or any other plug-in to be installed. The YouTube site had a page that allowed supported browsers to opt into the HTML5 trial. Only browsers that supported HTML5 Video using the MP4 (with H.264 video) or WebM (with VP8 video) formats could play the videos, and not all videos on the site were available.On January 27, 2015, YouTube announced that HTML5 would be the default playback method on supported browsers. YouTube used to employ Adobe Dynamic Streaming for Flash, but with the switch to HTML5 video now streams video using Dynamic Adaptive Streaming over HTTP (MPEG-DASH), an adaptive bit-rate HTTP-based streaming solution optimizing the bitrate and quality for the available network. Uploading All YouTube users can upload videos up to 15 minutes each in duration. Users can verify their account, normally through a mobile phone, to gain the ability to upload videos up to 12 hours in length, as well as produce live streams. When YouTube was launched in 2005, it was possible to upload longer videos, but a ten-minute limit was introduced in March 2006 after YouTube found that the majority of videos exceeding this length were unauthorized uploads of television shows and films. The 10-minute limit was increased to 15 minutes in July 2010. In the past, it was possible to upload videos longer than 12 hours. Videos can be at most 128 GB in size. Video captions are made using speech recognition technology when uploaded. Such captioning is usually not perfectly accurate, so YouTube provides several options for manually entering the captions for greater accuracy. YouTube formerly offered a 'Community Captions' feature, where viewers could write and submit captions for public display upon approval by the video uploader, but this was deprecated on September 28, 2020. (Captions that have already been added using the feature will be retained.)YouTube accepts nearly all consumer video and audio encodings, including but not limited to MPEG-1, MPEG-2, H.264 AVC, H.265 HEVC, VC-1, VP8, VP9, and AV1 for video and MP3, linear PCM, AAC, FLAC, Vorbis, Opus, and Dolby Digital (also known as AC-3) for audio. Nearly any container format can be used, including but not limited to MP4, Matroska, FLV, AVI, WebM, 3GP, MPEG-PS, and the QuickTime File Format. Some intermediate video formats (i.e., primarily used for professional video editing, not for final delivery or storage) are also accepted, such as ProRes. YouTube does stipulate a "recommended" upload format to maximize the quality of the transcoded video that will be shown to viewers; as of late 2020 this is H.264 AVC video and AAC audio in an MP4 container.Videos with progressive scanning or interlaced scanning can be uploaded, but for the best video quality, YouTube suggests interlaced videos be deinterlaced before uploading. All the video formats on YouTube use progressive scanning. YouTube's statistics shows that interlaced videos are still being uploaded to YouTube, and there is no sign of that dwindling. YouTube attributes this to uploading of made-for-TV content. Quality and formats YouTube originally offered videos at only one quality level, displayed at a resolution of 320×240 pixels using the Sorenson Spark codec (a variant of H.263), with mono MP3 audio.

In July 2010, YouTube announced that it had launched a range of videos in 4K format, which allows a resolution of up to 4096×3072 pixels. In March 2015, support for 4K resolution was added, with the videos playing at 3840 × 2160 pixels. In June 2015, support for 8K resolution was added, with the videos playing at 7680×4320 pixels. In November 2016, support for HDR video was added which can be encoded with Hybrid Log-Gamma (HLG) or Perceptual Quantizer (PQ). HDR video can be encoded with the Rec. 2020 color space.In June 2014, YouTube began to deploy support for high frame rate videos up to 60 frames per second (as opposed to 30 before), becoming available for user uploads in October.

In April 2011, YouTube announced the rollout of YouTube Live, with a portal page at the URL "www.youtube.com/live". The creation of live streams was initially limited to select partners. It was used for real-time broadcasting of events such as the 2012 Olympics in London. In October 2012, more than 8 million people watched Felix Baumgartner's jump from the edge of space as a live stream on YouTube.In May 2013, creation of live streams was opened to verified users with at least 1,000 subscribers; in August of that year the number was reduced to 100 subscribers, and in December the limit was removed. In February 2017, live streaming was introduced to the official YouTube mobile app. Live streaming via mobile was initially restricted to users with at least 10,000 subscribers, but as of mid-2017 it has been reduced to 100 subscribers. Live streams can be up to 4K resolution at 60 fps, and also support 360° video. In February 2017, a live streaming feature called Super Chat was introduced, which allows viewers to donate between $1 and $500 to have their comment highlighted. 3D videos In a video posted on July 21, 2009, YouTube software engineer Peter Bradshaw announced that YouTube users could now upload 3D videos. The videos can be viewed in several different ways, including the common anaglyph (cyan/red lens) method which utilizes glasses worn by the viewer to achieve the 3D effect. The YouTube Flash player can display stereoscopic content interleaved in rows, columns or a checkerboard pattern, side-by-side or anaglyph using a red/cyan, green/magenta or blue/yellow combination. In May 2011, an HTML5 version of the YouTube player began supporting side-by-side 3D footage that is compatible with Nvidia 3D Vision. The feature set has since been reduced, and the 3D feature currently only supports red/cyan anaglyph with no side-by-side support. 360-degree videos In January 2015, Google announced that 360-degree video would be natively supported on YouTube. On March 13, 2015, YouTube enabled 360° videos which can be viewed from Google Cardboard, a virtual reality system. YouTube 360 can also be viewed from all other virtual reality headsets. Live streaming of 360° video at up to 4K resolution is also supported.In 2017, YouTube began to promote an alternative stereoscopic video format known as VR180, which is limited to a 180-degree field of view but is promoted as being easier to produce than 360-degree video and allowing more depth to be maintained by not subjecting the video to equirectangular projection. Community On September 13, 2016, YouTube launched a public beta of Community, a social media-based feature that allows users to post text, images (including GIFs), live videos and others in a separate "Community" tab on their channel. Prior to the release, several creators had been consulted to suggest tools Community could incorporate that they would find useful; these YouTubers included Vlogbrothers, AsapScience, Lilly Singh, The Game Theorists, Karmin, The Key of Awesome, The Kloons, Peter Hollens, Rosianna Halse Rojas, Sam Tsui, Threadbanger and Vsauce3.After the feature has been officially released, the community post feature gets activated automatically for every channel that passes a specific threshold of subscriber counts or already has more subscribers. This threshold was lowered over time, from 10000 subscribers to 1500 subscribers, to 1000 subscribers, which is the current threshold as of September 2019.Channels that the community tab becomes enabled for, get their channel discussions (the name before March 2013 “One channel layout” redesign finalization: “channel comments”) permanently erased, instead of co-existing or migrating. YouTube offers users the ability to view its videos on web pages outside their website. Each YouTube video is accompanied by a piece of HTML that can be used to embed it on any page on the Web
