The EGG format is used to apply multiple different compression algorithms, choosing the algorithm based on the file extension. For example, it may use Bzip2 to compress .txt files, while using Deflate for files with a .exe extention. For .com or .sys files, ALZip uses the ALZ algorithm. The ALZ algorithm is slower but has a high compression ratio.
7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as "archives". It is developed by Igor Pavlov and was first released in 1999. It is developed by Igor Pavlov and was first released in 1999.
A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation .
bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm.It only compresses single files and is not a file archiver.It relies on separate external utilities such as tar for tasks such as handling multiple files, and other tools for encryption, and archive splitting.
Decompression speed is higher than bzip2, but lower than gzip. Compression can be much slower than gzip, and is slower than bzip2 for high levels of compression, and is most useful when a compressed file will be used many times. [4] [5] XZ Utils consists of two major components: xz, the command-line compressor and decompressor (analogous to gzip)
Terse files are compressed using a modification of Ziv, Lempel compression algorithm developed by Victor S. Miller and Mark Wegman at the Thomas J. Watson Research Center in Yorktown Heights, New York. [2] [3] The Terse algorithm was proprietary to IBM; however, IBM has released an open source Java decompressor under the Apache 2 license. [4]
Each compression specification defines various mechanisms by which raw video (in essence, a sequence of full-resolution uncompressed digital images) can be reduced in size, from simple bit compression (like Lempel-Ziv-Welch) to psycho-visual and motion summarization, and how the output is stored as a bit stream. So long as the encoder component ...
VP8 is an open and royalty-free video compression format released by On2 Technologies in 2008.. Initially released as a proprietary successor to On2's previous VP7 format, VP8 was released as an open and royalty-free format in May 2010 after Google acquired On2 Technologies.
