GIF was one of the first two image formats commonly used on Web sites, the other being the black-and-white XBM. [5] In September 1995 Netscape Navigator 2.0 added the ability for animated GIFs to loop. While GIF was developed by CompuServe, it used the Lempel–Ziv–Welch (LZW) lossless data compression algorithm patented by Unisys in 1985.
High Efficiency Image File Format (HEIF) is a digital container format for storing individual digital images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text , audio and video.
The High-Efficiency Image File Format (HEIF) is a container for images and videos that improves compression while improving image quality and adding new benefits over older formats (JPEG, PNG, and ...
A low frame rate causes aliasing, yields abrupt motion artifacts, and degrades the video quality. Consequently, the temporal resolution is an important factor affecting video quality. Algorithms for FRC are widely used in applications, including visual quality enhancement, video compression and slow-motion video generation.
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
The HEVC standard defines two tiers: Main and High. [1] [2] The Main tier is a lower tier than the High tier. [1] [2] The tiers were made to deal with applications that differ in terms of their maximum bit rate. [1] The Main tier was designed for most applications while the High tier was designed for very demanding applications. [1]
