• Removes PSY options which have been replaced by the better modelling system.
• Improves noise estimation and smoothing across frames.
• Improves motion compensation adding camera movement, zoom, roll and higher speed motion handling.
  • Fixes a number of issues where some things would see more detail loss due to the roll in particular.
• Motion no longer gets counted as noise.
• Motion compensation more resistant to being led astray from noise in the patches.
• Adds Hue & Saturation modelling which work in combination with the luma curve for all planes.
• Calculates noise level of chroma planes separately rather than just plane 0.
• Chroma motion driven by the luma frame.
• Add avformat to probe framework to temporarily work around FFMS2 issue
