LosslessCut is a free, platform independent video editing software, which supports numerous audio, video and container formats. [4] [5]It is a graphical user interface, with MacOS, [6] Windows [7] and Linux [8] support, using the FFmpeg multimedia framework.
facebook.github.io /zstd / Zstandard is a lossless data compression algorithm developed by Yann Collet at Facebook . Zstd is the corresponding reference implementation in C , released as open-source software on 31 August 2016.
Lagarith – Video codec designed for strong lossless compression in RGB(A) colorspace (similar to ZIP/RAR/etc.) libtheora – A reference implementation of the Theora format, based on VP3, part of the Ogg Project; Dirac as dirac-research, a wavelet based codec created by the BBC Research, and Schrödinger, an implementation developed by David ...
The Linux kernel implementation of fixed-probability decoding in rc_direct(), for performance reasons, does not include a conditional branch, but instead subtracts range from code unconditionally. The resulting sign bit is used to both decide the bit to return and to generate a mask that is combined with code and added to range .
Lempel–Ziv–Welch (LZW) is a universal lossless data compression algorithm created by Abraham Lempel, Jacob Ziv, and Terry Welch.It was published by Welch in 1984 as an improved implementation of the LZ78 algorithm published by Lempel and Ziv in 1978.
Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy . [ 1 ]
FFV1 (short for FF Video 1 [1]) is a lossless intra-frame video coding format. FFV1 is particularly popular for its performance regarding speed and size, compared to other lossless preservation codecs, such as M-JPEG2000. [2] [3] [4] The encoder and decoder have been part of the free, open-source library libavcodec in the project FFmpeg since ...
Frequency-customized quantization scaling matrices selected by the encoder for perceptual-based quantization optimization An in-loop deblocking filter that helps prevent the blocking artifacts common to other DCT-based image compression techniques, resulting in better visual appearance and compression efficiency
