Founded in 2004, Vimeo is a popular website for sharing and viewing video content. Vimeo reportedly receives over 60 million visits per day. The site differentiates itself in several ways from YouTube. Firstly, it allows users to set privacy levels on a video, allowing users to define a password or to share with a select group of users. Users can also choose whether or not to allow others to embed video onto another website. Vimeo also offers upgraded accounts, for super users and business use. The site has a large artistic following, with a number of indie filmakers choosing Vimeo over other rivals. Vimeo was the first of the major video sharing sites to support user uploaded content in high definition.
Vimeo recommend that video is compressed using H.264 codec at 24, 25 or 30 frames per second. They also recommend choosing a resolution of 640x480 for standard definition and 1280x720 for high definition. Recommended audio encoding is AAC up to a maximum of 320 kbps. Video can be uploaded through a normal PC, but also from mobile devices. Vimeo allows users to upload video in a wide variety of formats, including MP4, DIVX, WMV, 3GP, and MOV.
MP4 files (MPEG-4 Part 14) are multimedia files. MP4 is a container format that can store video, audio and subtitle data (as well as more depending on content). Since stores like iTunes uses this container format, and it is used with iPod and PlayStation Portable (PSP), MP4 files have become more common.
MPEG-4 Part 14 or MP4, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital video and digital audio streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. A separate hint track is used to include streaming information in the file. The only official filename extension for MPEG-4 Part 14 files is .mp4.
