With more content and compatible TVs available every day, HDR video is the best way to get amazing looking video in your home. But as we learned making this video, it's also a lot more complicated than it seems (and no we didn't master this in HDR). Add in three or four competing standards, and there's a lot to unpack.

I own a 65 inch LG OLED C6 that is capable of 3D, HDR10 at 60hz and Dolby Vision at 30hz. I have an Apple TV 4K hooked up to it, but I mostly use the KZfaq app in WebOS.

@@AKSBSU it is because there is a different calibration for Dolby vision vs HDR10. And actually dolby vision is wrongly calibrated. There is not so many differences between them except that ICtCp can give more colors with lower bitrate and dynamic metadata is a little better than Dynamic Tone mapping. But idrally there should not be many differences.

Very well explained. Even a few years into 4K and with 8K on the horizon, I find the gains in resolution to be almost negligible at normal viewing distance. But HDR is definitely something that can make certain movies and video games look much better. It'd be just nice if there weren't that many standards involved and wildly varying levels of peak brightness from screen to screen. An HDR400 monitor is kind of lackluster compared to a screen with an actual peak brightness of 1000 nits. (though it can still look noticably nicer than SDR)

I completely agree HDR is waaaay more impressive and important than 4k is. It completely changes the viewing experience and I'm continually in awe pausing and rewinding. Side note* after 2 trys with the q70t and various issues we are waiting for our 75" Sony x900h that supports dolby vision and I'm soooo excited to experience dolby vision. I'm excited to see if I can notice a difference compared to hdr 10/ 10+ that the samsung supported. Great video and extremely well put to gether to explain all of this. Thank you!!!

I still remember watching Equilibrium on a CRT projector that was calibrated so that black literally does not produce any visible light. The first action scene was spectacular. And so I'm ambivalent about this HDR stuff. I've always been a sucker for rich blacks and strong contrasts but most TVs labelled HDR-ready can't even support that because of the underlying technology, so I can't really find myself caring as much as I care about things such as OLED or MicroLED.

Amazing talk, can you explain one more thing: doesn’t the log curve compress color AND luminance data, so that a wider ranger of data can be held in the same container. Sony’s 8 bit cameras use their slog mode to use a log function to hold more than 8 bits of data in that 8 bit container, correct? I didn’t think it was just a straight mapping of values, I thought it was a function of reducing data to log points, then in post you reverse the log and then have more data to work with

Hi Chris. Great video . Now there are many like me who have backed the nebula cosmos max from anker.(4k pixel shifting 0.47 m chip and 1080 cosmos with 0.33 dmd chip) I wanted your guidance on this. PPL r hving issues with dark movies as they r very dark especially in the 1080 model ..now hdr on and off has been added. Also in developer mode it has toggle for srgb. Why is this dark movie issue troubling us ? PPL have improved it in the 4k one by changing linear settings on the max but cosmos for now doesn't have that. Now both were suppoaed to hve hdr 10 and hlg and dyic smoothing. How do we make full use of this ? Wht do we tell the developers to do to make us enjoy this feature? How do we use sRGB to improve colours. I have posted this video on our nebula cosmos family group for them to understand better . Pl give your inputs on these two questions

@sparkside217 4 жыл бұрын

One thing I'm confused about - on a 1080p regular blu-ray release, compared to it's 4k release with more color depth, how does the tv treat the two discs? Is it that 1080p releases generally have lighter blacks/less highlights, and if so, will the tv show it as so? Or will the TV artificially widen the color so that the deepest black on the disc is presented as the deepest black the tv can do? If so, what are the downsides of this?

@florichi 4 жыл бұрын

The TV could do both. Either display the image as intended with a 0-100nit dynamic range and REC 709 colors (most TVs are close to that with cinema picture styles enabled or if they are calibrated), or stretch it out to use a wider dynamic range (TVs do that in the vivid, sports or other similiar) and boost colors plus use a denoiser/banding filter. If you want the picture as the director wanted it approach nr. 1 would be the one to go with. If you are the store that want's to sell the TV by tricking the buyer, then use approach nr 2. But: Even if the two modes, SDR and HDR, are calibrated to the standards, the difference in color will mostly be minor, since only the very vivid parts of the image will see a difference. Recent HDR releases never really use the REC 2020 colorspace, since they either know that TVs can't display it or the muted look suits the movie.
