Several codecs compression ratio comparison


We've compared results of proposed algorithm with other available codecs results.

The comparison was made mostly on classic sequences frequently used for codecs comparisons, their descriptions are given below. Also we added two sequences ms2.avi and ms32.avi taken from "The Matrix: Reloaded" movie passed through DivX.

The comparison was made in RGB and YUV color spaces because usually models used by codecs and their efficiency differ a lot depending on the color space. Also, not all of the codecs support YUV though it usually gives a better compression.

As seen from the graphs below, MSU Lossless Video Codec gives the best result compared to all of the available codecs.


Configuration


In the main configuration dialog you can set two main parameters - video quality and compression mode. There are following variants of video quality:

Compression Mode influences compression ratio and compression/decompression speeds with given quality. You can choose one of preset parameters sets or the manual tuning mode.

When choosing any variant of quality and compression mode, graphics in the top side of the window show expected quality, compression ratio, compression speed and decompression speed.

When compressing interlaced sequences you can turn on the Compressing interlaced movie option. In some cases it improves compression.

The Advanced window:
Again, any changes of parameters cause graphics to show expected results.

Compression method allows you to choose compression algorithm - the new one or the old one. The new one is much faster on compression and decompression, but the old one gives better compression on most files (but on some files the new method works better).

In Denoising area you can set denoising parameters for Custom compression mode.

In Delta-Frames area you can set up codec's use of previous frames. In Motion Estimation you can control compression speed and ratio. You can use one of presets or set the following options manually.
