Real 4K HDR 24fps: Downtown Milford, CT - HDR on Samsung 4K UHD TV's, HDR Phones & Chromecast Ultra.

Downtown Milford, CT, on May 16, 2017.
The number of devices that can actually view this in HDR is small. So, if you can view this using a supported HDR device, let me know how it looks in the comments below.
This video is my 2nd attempt at grading & publishing a 4K HDR (high dynamic range) KZread video. This time I included a LUT (Look Up Table) that instructed KZread how to process the HDR video for viewing on non-HDR devices. Watch in actual HDR on select Samsung 4k TV's, HDR Phones & Chromecast Ultra devices currently. All other devices will play this video as 4K or HD in SDR (standard dynamic range).
The KZread auto-conversion from HDR to SDR does not work well. In SDR, the brightest whites clip terribly and lose all their texture detail. There are also saturation and color accuracy issues. So, I apologize if this doesn't look very good on your device or TV in SDR. I'm currently working on a fix that will allow me to tell KZread how optimize the conversion for my specific video.
Filmed using my Sony NEX-FS700R with a Canon EF 40mm f/2.8 STM lens on an Atomos Shogun recorder as 4K CDNG raw video. Edited and graded entirely in Davinci Resolve 12.5.

    I watched this in HDR on my Samsung S8 phone. The DR is impressive - one can see the difference HDR makes. But the colors are way off - the reds are orange and the greens are just not right. My HDR video, shot with the GH4 to Atomos Shogun Inferno from Vlog 10bit 422 looks fine in HDR: kzread.info/dash/bejne/a4uGuZWfaL2th7Q.html , so it is not a KZread problem. I have an FS700R also. How did you grade from RAW?

    That's too bad. Thanks for the info. Yeah, I'm pretty much grading blind. The only way I have to monitor the HDR footage is using scopes for luma. And then I upload short clips to KZread to watch on my Samsung TV for the color. It looks great on my TV, but I've got no other ways to watch it in HDR. What's interesting is that I had to make a custom LUT for the KZread HDR-SDR conversion otherwise most of the colors looked off.

    I did all grading and editing in Resolve 12.5. And then used mkvmerge to setup the HDR info and embed the LUT.
