And it is exactly what it looks like when I try to play on the Disney+ app on my TV. But not when I watch in a web browser or stream it through chromecast. I prefer to share what the image really looks like, not a partial and incomplete version.
There are some HDR to SDR converted stills out there now over at the Star Wars Trilogy forum, if the lack of tone mapping really sets you off that much.
I posted these “incomplete” screengrabs so people could see the full detail in the 4K image, FWIW. I do hope someone was able to properly compare them to the Blu-ray.
It’s a clear 1080p upscale to my eyes.
Can that be done? And would it yield a 10 or even 12 bit image? That would be awesome!
As for whether this changes anything for Despecialized, yes, the change is that I will now definitely be waiting for the 4K Blu-Ray or at least a full bitrate 4k web-dl as a source.If you’re asking if it’s possible to extract the flat image? Yes. The HDR grade is stored as metadata on UHD discs, so you can easily retrieve the flat image. As for the bit depth, I believe they’re all 10bit video files.
Well, technically it’s the HDR Output Display Transform (ODT) that’s included in the metadata, as well as the individual shot-for-shot metadata tweaks (HDR custom trims). But the grade itself is actually performed on the log level of the image, so the flat image still has a grade applied to it (just not the HDR ODT). In other words, the “log” image is a graded log image, but it just doesn’t have a contrast curve applied to it yet.
Very interesting, thank you for the explanation!
