MSU Lossless Video Codec 0.6.0

MSU Lossless Video Codec 0.6.0 is a nice addition to your codec collection. It is actually a free high quality lossless video codec. This codec is intended for lossless video compression (used for saving master copies or intermediate rendering results). It has the best compression ration among free lossless video codecs. This codec supports RGB, YUY2 and YV12. It also allows to set up speed/compression ratio compromise by choosing appropriate motion compensation algorithm. Allows to set up loss/compression ratio compromises. Performs accurate denoising in temporal and spatial domains during lossy compression. Denoising often improves quality of video.

Benefits:

• Variants of video quality:
  
• • Absolutely lossless - absolutely lossless mode: the data after decompression is bitwise equal to the source data. This mode has the smallest compression ratio. Input may be in RGB, YUY2 and YV12 formats, output will be in the same format as input.
    
  • Allow colorspace conversion - works in YV12 color space. It means if you had some video in YV12 format (quite often case) then after decompression the data is equal to the source. And if the source data were in 24-bit RGB or 16-bit YUY2, then you lose on RGB to YUV conversion. This mode leads to much better compression ratio.
  • Allow denoising - differs from previous one by having a slight denoising. Visually image stays the same but compression improves.
    
  • Allow stronger denoising - differs from the previous one by stronger denoising. Visually image quality doesn't get worse (in most cases it gets better) and the compression ratio grows further.
• In Denoising area you can set denoising parameters for Custom compression mode.
  
• • Temporal denoising threshold controls the temporal part of denoising. Must be a positive integer number. The "Good compression" mode has this parameter set to 30, the "High compression" mode - 50.
    
  • Spatial denoising intensity controls the spatial part of denoising. Must be a positive real number. The "Good compression" mode has this parameter set to 4, the High one - 20.
• In Delta-Frames area you can set up codec's use of previous frames.
  
• • Enable Delta-Frames turns on delta-frames use. If you turn it off, all frames will be key-frames. This will cause growth of file size, so don't turn it off unless you're sure you need to.
    
  • Force Key-Frames every N frames tells codec to insert a key-frame at least once an N frames.
• In Motion Estimation you can control compression speed and ratio. You can use one of presets or set the following options manually.
  
• • FullSearch turns on use of slow but precise algorithm of motion compensation. It makes compression much slower but much better.
    
  • After DVD or DivX: turning this option on allows you to compress better video which passed through a lossy codec.
    
  • PP-frame - search in pre-previous frame. Makes compression a bit slower but better. Recommended to keep it turned on.
