Comparison of video codecs. Α video codec is software or a device that provides encoding and decoding for digital video, and which may or may not include the use of video compression and/or decompression. Most codecs are typically implementations of video coding formats. The compression may employ lossy data compression, so that quality ...
Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
MPEG-1 is a standard for lossy compression of video and audio.It is designed to compress VHS-quality raw digital video and CD audio down to about 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) [2] without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) practical.
Data compression ratio is defined as the ratio between the uncompressed size and compressed size: [1][2][3][4][5] Thus, a representation that compresses a file's storage size from 10 MB to 2 MB has a compression ratio of 10/2 = 5, often notated as an explicit ratio, 5:1 (read "five" to "one"), or as an implicit ratio, 5/1.
The H.264 video format has a very broad application range that covers all forms of digital compressed video from low bit-rate Internet streaming applications to HDTV broadcast and Digital Cinema applications with nearly lossless coding. With the use of H.264, bit rate savings of 50% or more compared to MPEG-2 Part 2 are reported.
A The maximum bit rate of the profile is based on the combination of bit depth, chroma sampling, and the type of profile. [3] For bit depth the maximum bit rate increases by 1.5x for 12-bit profiles and 2x for 16-bit profiles. [3] For chroma sampling the maximum bit rate increases by 1.5x for 4:2:2 profiles and 2x for 4:4:4 profiles. [3]
VP9 is the last official iteration of the TrueMotion series of video formats that Google bought in 2010 for $134 million together with the company On2 Technologies that created it. The development of VP9 started in the second half of 2011 under the development names of Next Gen Open Video (NGOV) and VP-Next. [8][9][10] The design goals for VP9 ...
Vimeo Help Center. Retrieved 17 July 2023. ^ The Vimeo API has a limit of 250 GB and 24 hours per video file. This is applicable to all new plans, and to legacy Pro Unlimited, Business and Premium plans. Other legacy plans have different file size limits: 500 MB for Basic, 5 GB for Plus, and 20 GB for Pro.
