Versatile Video Coding (VVC), standardized in 2022 as ITU-T Recommendation H.266, ISO/IEC 23090-3 and MPEG-I Part3, is the latest block-based hybrid video coding standard which claims to fulfill all the requirements of todays and tomorrow's video applications. VVC defines more tools to increase compression efficiency while maintaining the same level of quality. The tradeoff is the computational complexity. H.266/VVC, especially the intra-coding loop, is computationally very complex due to its nature of iteratively trying all possible QTMT partitioning tree alternatives with all options of compression technologies. In this paper, we focus on the intra-coding loop of VVC for 8K video and study the effects of technologies like MTS, LFNST, MIP etc. on the compression efficiency (bits), quality (Y-PSNR), and computational complexity (runtime). By switching off all those optional technologies, we observe 46.07% runtime gain with only 5.00% increase in bitrate, and 0.0423 dB decrease in Y-PSNR on average. Since this is a remarkable gain in complexity with a limited effect on efficiency and quality, this tradeoff can be taken into consideration for many 8K applications utilizing VVC.
