MSU Lossless Codecs ComparisonThe name of this video codec category declares full quality losses absence - the decompressed video stream should be completely identical to original. Output quality is same for all codecs. Absolute absence of losses is a very strong requirement, therefore it is often hard to achieve compression ratios above 3:1. Some of the tested codecs have an opportunity of work in "lossy" mode; it allows to reach considerably higher compression degree with rather small losses of quality. However, only "fully lossless" mode is considered in the current comparison. The only parameter of comparison is the compression level.
