Excellent answer thxquietvoid wrote: ↑Tue Jun 20, 2023 11:13 amWhy do you believe the metadata is any better for quality? It's literally only required to decode the colours into regular PQ/BT.2020.Trees wrote: ↑Tue Jun 20, 2023 9:10 amVery interesting. I never knew extracting the RPU and injecting it in to a remux was a lossy progress. I thought it truly was the best of both worlds. It seems P5 DV is still absolute best, as it's in the IPTPQc2 colour space and includes both chroma and luma mapping; it's just lacking the bit rate of a Blu-ray.
Which begs the next question; seeing as the IPTPQc2 has been reverse engineered by gifted folk, as it can be decoded by MPV to be properlt played back, is it possible to convert the Blu-ray high bit-rate stream to the IPTPQc2 colour space and inject the lossless RPU to truly get best of both worlds?
It doesn't improve the quality at all on playback. The process is only lossy in that it loses the original metadata, the quality is unaffected.
And any reencoding of a Blu-ray into IPT would be worse as transcoding is lossy.
