HDR computer displays have seen the lowest amount of available displays and general adoption but I expect to see more coming to market at CES in January of 2019.įortunately, platforms like YouTube and Vimeo will automatically convert a copy of your HDR10 video as SDR and serve that which may give some the appearance that SDR players can play HDR videos. The latest IPhones and Android phones might have HDR support. Televisions manufactured since 2016 might have HDR10 support especially if the cost was over $2000 to $3000. If you try and display an HDR video on an SDR display it will likely look de-saturated with a flat low-contrast look like LOG footage. Those who work with the most high end professional graphics might have a 10-bit display on their workstation however they likely don't meet the 1000 nits brightness required for the current common standard HDR10. YOU PROBABLY CANNOT SEE HDR (SPECIAL HARDWARE REQUIRED) Most of today's display devices like Smartphones, Televisions, and LCD Monitors use SDR. Nits are a candle power unit and we're going from 120-300 nits on all of our phones, televisions, and computer displays to 1000 nits initially for HDR10 with plans to go to 10,000 nits and beyond. When HDR content is displayed on a 2,000 cd/m2 display with a bit depth of 10-bits per sample it has a dynamic range of 200,000:1 or 17.6 stops, a range not offered by the majority of current displays." - Wikipedia article on High Dynamic Range Video Professional SDR video with a bit depth of 10-bits per sample has a dynamic range of about 10 stops. ![]() SDR video with a conventional gamma curve and a bit depth of 8-bits per sample has a dynamic range of about 6 stops. "The dynamic range that can be perceived by the human eye in a single image is around 14 stops. With HDR you can store and display more dynamic range so there is less of an extreme tradeoff on keeping your highlights. In an SDR world you choose to expose the clouds and silhouette the room OR you expose the room and let the window blow out. To have a higher dynamic range means being able to record or display more detail in the darkest and brightest parts of an image.Ĭonsider the image above of the window and imagine how you might solve the problem of exposing the bright clouds outside without blowing them out while also getting good exposure inside the dark house for a painting on the inside wall next to the window for example. The concept of "dynamic range" for video describes the ratio between the maximum and minimum measurable light intensities (black and white). I can upload at around 15Mbps according to so I might even tolerate at 50GB file upload as it would take about 8 hours to transfer while I sleep at night.
