Hamza Status 1 is a YOUTUBE Channel, Created MUHAMMAD HAMZA AHMED ON:17DEC 2020, this YOUTUBE channel for entertainment to make happy channel link: //www.youtube.com/channel/UCgjSryZubOPks0QQSYfypdA Facebook: YouTube and selected creators earn advertising revenue from Google AdSense, a program that targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Music and YouTube Premium, subscription services respectively offering premium and ad-free music streaming, and ad-free access to all content, including exclusive content commissioned from notable personalities.

As of February 2017, there were more than 400 hours of content uploaded to YouTube each minute and one billion hours of content being watched on YouTube every day. As of October 2020, YouTube is the second-most popular website in the world, behind Google, according to Alexa Internet.[6] As of May 2019, more than 500 hours of video content are uploaded to YouTube every minute.[7] Based on reported quarterly advertising revenue, YouTube is estimated to have US$15 billion in annual revenues.

YouTube has faced criticism over aspects of its operations, including its handling of copyrighted content contained within uploaded videos,[8] its recommendation algorithms perpetuating videos that promote conspiracy theories and falsehoods,[9] hosting videos ostensibly targeting children but containing violent or sexually suggestive content involving popular characters,[10] videos of minors attracting pedophilic activities in their comment sections,[11] and fluctuating policies on the types of content that is eligible to be monetized with advertising 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.[99][100] 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.[101] The 10-minute limit was increased to 15 minutes in July 2010.[102] In the past, it was possible to upload videos longer than 12 hours. Videos can be at most 128 GB in size.[99] 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.[103] 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.)[104]

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.[105] 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.[106]

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.[107] 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.[108]

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),[109][110] with mono MP3 audio.[111] In June 2007, YouTube added an option to watch videos in 3GP format on mobile phones.[112] In March 2008, a high-quality mode was added, which increased the resolution to 480×360 pixels.[113] 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.[114] 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.[115][116] 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.[117] In November 2016, support for HDR video was added which can be encoded with Hybrid Log-Gamma (HLG) or Perceptual Quantizer (PQ).[118] HDR video can be encoded with the Rec. 2020 color space.[119]

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.[120][121][122][123]

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.[124]
