Tests of Live VVC 8K 60fps Encoding Detailed & Demoed At IBC 2023

8K Association | Oct 9, 2023 |

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.

Analyzing SVT-AV1 Presets: Size, Quality, and Speed with CRF Variations

OTTVerse | Aug 15, 2023 |

SVT-AV1 is a video codec that provides quality compression with fast encryption. This experiment tested speed vs quality tradeoffs by varying CRF values and presets in FFmpeg. Results reveal preset 8-12 are best for fast encoding while preset 2-4 produce high-quality video but take longer. Adjusting these parameters allows users to customize their encoding settings to suit their specific needs.
