[XviD-devel] Something to read: Rate-Distorsion optimization

[Christoph Lampert]

Hi,

since I know that all of you are extremely eager to learn new stuff >;->
so here are a few links if you are interested in 

"Rate Distorsion Optimization"

which covers e.g. "Optimal" Adaptive Quantization, "Optimal" Quantization
(like ffmpeg's trellis) and "Optimal" Mode Decision. It's also the
background for the constants we penalize long vectors in motion estimation
etc.
