TUNE c [file [color-diff]] Collect statistics on Quantization |
| 47 |
|

TUNE d [RateScale DistortionScale] Do a DCT in the P search, not just DIFF |

TUNE k [breakpt end [slope]] Squash small lum values |

TUNE n Dont consider DC differenece in DCT searches |

TUNE u disallow skip blocks in B frames |
