To show off the incredible image capabilities of its latest smartphone chipset, Qualcomm has shared a 4K HDR video filmed on a prototype smartphone powered by its Snapdragon 855 Mobile Platform. The video, which was filmed in Maui, Hawaii during Qualcomm's Snapdragon Tech Summit in December 2018, was captured on a development platform—effectively a prototype smartphone—equipped with Sony's 22.
5-megapixel IMX318 image sensor at the heart of it. The footage was shot in the HDR 10 format with 10-bit color depth and in the Rec. 2020 color gamut. It's worth noting the Snapdragon 855 is actually capable of both recording and playing back HDR 10+, which uses dynamic metadata instead of static metadata to provide more accurate rendering, so newer smartphones with even better image sensors could technically pull more impressive footage than what's shown in the above video.

Qualcomm notes in its explainer blog post that the footage captured with compatible smartphones works with YouTube HDR, so it's ready to share in its full dynamic range glory straight from compatible devices. In fact, you'll want to watch the above video on a Youtube HDR-certified smartphone or TV to realize the extended contrast and color gamut, as opposed to on a traditional computer and display.
Below are a few behind-the-scenes photos of the video shoot on Maui:

According to Qualcomm's website there are 11 smartphones currently confirmed to be using the Snapdragon 855 chipset: the OnePlus 7 Pro 5G, OPPO Reno 5G, ZTE Axon 10 Pro 5G, Motorola Moto z3 with 5G Moto Mod, LG V50 ThinQ 5G, Xiaomi Mi MIX 3 5G, Samsung Galaxy S10 5G, Sony Xperia 1, LG G8 ThinQ, Xiaomi Mi 9 and Samsung Galaxy S10. However, not all of those are confirmed to support the 4K HDR video capabilities, as it's up to the device manufacturer to make use of the Snapdragon 855's video capabilities.
