VVC has a better coding efficiency relative to predecessor standards (HEVC and AVC), but also achieves increased complexity. VVC standardization committee seeks to achieve more effective compression, particularly for 4K and 8K contents by reducing the bitrate of compressed videos by 50% while maintaining the same level of objective and subjective quality. However, these tools negatively deliver the computational cost of the VVC. Because VVC requires a fairly large delay in video encoding, it is necessary to optimize the encoding process to obtain an optimal trade-off between efficiency and complexity of the coding process. To reduce encoding time, we propose an optimization method for VVC in this paper which can achieve VVC usage in live video communication, which requires as little coding time as possible to reduce delay time. Accordingly, we formulate an optimization for VVC usage conditions in live video communication at low bitrate and low resolution CIF (352×240) and QCIF (176×120). Experiment results show that this paper proposed method can reduce coding time (t %) average up to -67.51% through setting the initial VVC parameters with insignificant quality degradation.
