About the comparison of lossless codecs
The 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.
Many codecs give an opportunity to adjust the parameter speed/compression
ratio; it allows to tune the codec for the specific task (real-time capture
or the rendering requiring loss minimization). Only maximum compression ratio result
is considered in current work.
Some codecs are capable to accept input data in several color spaces (RGB, YUY2, YV12, etc.), however,
compression is not always "lossless". Some codecs "silently" perform the conversion of color spaces, thus,
raising a degree of compression. Quality losses coming out of such conversions are not visible, but surely
exist. In the given testing work codecs is compared separately for various color spaces, thus in each color space
full absence of losses is guaranteed!
Main parts of the comparison:
- Information about codecs:
- Vendor and version
- Color space support
- Logo presence in compressed video
- Registration requirements
- Sequence name
- Resolution
- Number of frames
- Brief codecs description with screenshots
- Codecs comparison with analysis of compression ratios for each sequence
- Codecs comparison with analysis of total compression ratios for each codec
