YouTube accepts a wide range of video file formats.The video files below are all accepted by YouTube. Some video formats work best and are most compatible with certain computers, software or devices.
YouTube can accept almost any video format for upload, but for most users we have found the following settings give the best results. Here's a summary of the audio and video specifications you need for the best results on YouTube.
For further details, please read the information listed directly below this summary.
|Resolution||Recommended: 1280 x 720 (16x9 HD) and 640 x 480 (4:3 SD)
There is no required minimum resolution - in general the higher resolution the better and HD resolution is preferred. For older content, lower resolution is unavoidable.
|Bit rate||Because bit-rate is highly dependent on codec there is no recommended or minimum value. Videos should be optimized for resolution, aspect ratio and frame rate rather than bit rate.|
|Frame rate||The frame rate of the original video should be maintained without re-sampling. In particular pulldown and other frame rate re-sampling techniques are strongly discouraged.|
|Codec||H.264, MPEG-2 or MPEG-4 preferred.|
|Codec||MP3 or AAC preferred|
If you do not think your current video file format is recognized by YouTube, you may get the best uploading results from converting your file to MPEG4 video with MP3 audio with Video Converter for Mac.
Keep in mind that each time you convert or "transcode" a video from one type of compression to another, there will be some loss in quality, similar to making a photocopy of a photocopy.
Avoid transcoding a highly compressed video into a format that is accepted as this produces poor results. You'll get better results by going back to your original video editing software (where you initially edited the video), and re-exporting in a format such as MPEG4 with MP3 audio.
YouTube is a video sharing website on which users can upload and share videos. Three former PayPal employees created YouTube in February 2005. In November 2006, YouTube, LLC was bought by Google Inc. for $1.65 billion, and is now operated as a subsidiary of Google.
The company is based in San Bruno, California, and uses Adobe Flash Video technology to display a wide variety of user-generated video content, including movie clips, TV clips, and music videos, as well as amateur content such as video blogging and short original videos. Most of the content on YouTube has been uploaded by individuals, although media corporations including CBS, the BBC, UMG and other organizations offer some of their material via the site, as part of the YouTube partnership program.
Unregistered users can watch the videos, while registered users are permitted to upload an unlimited number of videos. Videos that are considered to contain potentially offensive content are available only to registered users over the age of 18. The uploading of videos containing defamation, pornography, copyright violations, and material encouraging criminal conduct is prohibited by YouTube's terms of service. Accounts of registered users are called "channels."
YouTube offered the public a beta test of the site in May 2005, six months before the official launch in November 2005. 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. 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 percent and more than six billion videos viewed in January 2009. It is estimated that 20 hours of new videos are uploaded to the site every minute, and that around three quarters of the material comes from outside the United States. It is also estimated that in 2007 YouTube consumed as much bandwidth as the entire Internet in 2000. In March 2008, YouTube's bandwidth costs were estimated at approximately US$1 million a day. Alexa ranks YouTube as the fourth most visited website on the Internet, behind Google, Yahoo! and Facebook.
In October 2006, Google Inc. announced that it had acquired YouTube for US$1.65 billion in Google stock, and the deal was finalized on November 13, 2006. Google does not provide detailed figures for YouTube's running costs, and YouTube's revenues in 2007 were noted as "not material" in a regulatory filing. In June 2008 a Forbes magazine article projected the 2008 revenue at US$200 million, noting progress in advertising sales.
In November 2008, YouTube reached an agreement with MGM, Lions Gate Entertainment and CBS which will allow the companies to post full-length films and television shows on the site, accompanied by advertisements. The move is intended to create competition with websites such as Hulu, which features material from NBC, Fox, and Disney.
