Content creators praised 8K capture development at a 4K HDR event in Malaga, Spain. Olivier Chiabodo from The Explorers discussed 8K video capture with Chinese engineers. Prashant Chothani of TravelXP suggested satellite delivery for high quality video and Ulrich Grönewald of Synamedia argued for lower transmission cost to allow wider adoption of 8K. Synamedia works with AMD to speed up 8K encoding, allowing for higher frame rates and VR/360 applications. Paul Gray of Omdia also sees potential for 8K content capture and production in VR headsets.

This paper presents a VVC/H.266 encoder capable of 8Kp60 10-bit HDR real-time encoding with 24% lower bitrate than SpinHEVC. Tests on Intel Xeon Scalable Processors showed up to 70 fps at 30 Mbps and 40 Mbps at 60 fps for 8K video, proving its viability. It had minimal latency and MS-SSIM study revealed higher quality compared to HEVC and AV1. Future research will optimise it further.This paper presents a VVC/H.266 encoder capable of 8Kp60 10-bit HDR real-time encoding with 24% lower bitrate than SpinHEVC.

Meta has made it possible for people to upload high dynamic range (HDR) videos from their phone’s camera roll to Reels on Facebook and Instagram. To show standard dynamic range (SDR) UI elements and overlays legibly on top of HDR video, we render them at a brightness level comparable to the video itself. We solved various technical challenges to ensure a smooth transition to HDR video across the diverse range of old and new devices that people use to interact with our services every day. Over the past year, the Video Infrastructure teams at Facebook and Instagram have seen a significant increase in the amount of HDR content being uploaded to our apps, with millions of HDR videos uploaded every day. As a result, we have been working to bring true HDR video support to our family of apps, starting with Reels. Today, people now have the ability to upload HDR videos from their phone’s camera roll to Reels and to have that video playback in full HDR . To make this possible, we…
