Motion Codecs : Predictor codec and Mhuffyuv codec

Updated: 28 Sep 2004

Lossless Windows codecs that compress motion (not only every frame separately).
The logic is very easy. One frame normaly differs only a little from the previous so the actual frame minus the previous frame may result many zeroes. And the zeroes can be compressed more than other number.
The bad side is that this is not allways true, and this frames can't be compressed very much. So only fixed images composed videos or animation movies ("cartoons") can be compressed better with those codecs.

These codecs have been done using the huffyuv codec like a skeleton.

Predictor codec:

This codec uses the "predictor" algorithm as decribed in the RFC 1978.
Is a fast lossless codec but with very little compression.

Mhuffyuv codec:

This codec is a modification of the original huffyuv codec to use "motion".

How to install Predictor codec and Mhuffyuv codec:

- Uncompress the files from archives, right-click on the mhuffyuv.inf/predictor.inf files and select Install.
- You may encounter a prompt saying: "The software you are installing for this hardware... has not passed Windows Logo testing..."; click on the Continue Anyway button.
- Then check the installed codec. See Checking Installed VIDEO and AUDIO Codecs In Windows XP guide.
