Tuning
- Quantization matrix
- Beta
- Inter band masking
- PVQ RDO
Known broken/suboptimal
- Block size decision
- Never tuned on inter
- Not considering chroma
New ideas
- VQ for inter frames, with codebook selected based on dim m
- Motion vector "mask" based on previous frame
- Use coeff magnitude correlation for modelling
Entropy coding
- Make the Laplace vector encoder (aka k-tokenizer) faster
- Add "skip-all remaining bands" flag
- Better encoding of the CfL sign
