That is what you say to Vincent's entire videos, one sentence?
. I knew I shouldn't have tried to summarize them - people pick at my summary instead of going off to watch them
And to me there’s no “heavy lifting” involved in any of the static tone mapping.
Again, I won't try to summarise Vincent's videos again. It is his phrase not mine. I cannot force you to watch them, only repeat my recommendation that you do. No offence or argument intended, really
What I would say which I didn't before (clearly enough), is that dynamic tone-mapping aka "look at the picture and guess", can very often and very easily make mistakes because it doesn't know what it coming up next. So:
- Any combination of settings which gives an improved picture whilst avoiding resorting to the TV's DTM is a good thing.
- DTM is a bandage for poor tone-mapping results on TVs when receiving 4000 nit content, or even worse, content that has had or false metadata.
- And neither of the above is ever needed at all, for the Dolby Vision or HDR10+ content which has dynamic metadata, scene-by-scene*, where you can give the TV the chance to do perfect tone-mapping by giving it perfect and accurate metadata.
For the 3rd case, not owning this player yet I would hope/expect it can obey the HDR10+ dynamic metadata, and perform the creator's instructed tone-mapping in the player, and then output the finished tone-mapped plain HDR10 stream to a HDR10-only TV. It would be crazy to them try to analyse that finished stream all over again in the TV using DTM, if you see what I mean.
