[1.7.0] - 2023-08-24
Encoder
- Improve the tradeoffs for the random access mode across presets MR-M13:
- Quality improvements across all presets and metrics ranging from 0.3% to 4.5% in BD-rate (!2129)
- Spacing between presets [M1-M6] has been adjusted to account for the tradeoff improvements achieved
- As a user guidance when comparing v1.7 vs v1.6 in a convexhull encoding setup:
- v1.7.0 M2 is now at similar quality levels as v1.6.0 M1 while being ~50% faster
- v1.7.0 M3 is now at similar quality levels as v1.6.0 M2 while being ~50% faster
- v1.7.0 M4 is now at similar quality levels as v1.6.0 M3 while being ~40% faster
- v1.7.0 M5 is now at similar quality levels as v1.6.0 M4 while being ~30% faster
- v1.7.0 M6 is now at similar quality levels as v1.6.0 M5 while being ~25% faster
- Added an experimental tune SSIM mode yielding ~3-4% additional SSIM BD-rate gains (!2109)
