Live Demonstration: Performance Comparison Between Ali266 and x265.

This is a live demonstration about performance comparison between Ali266, an optimized VVC software encoder implemented by Alibaba [1], and the open source HEVC software encoder x265 [2]. Visitors can play any pair of comparison videos. The video displayed on the screen is divided into left and right parts. The left part is encoded by the open source HEVC software encoder x265, and the right part is encoded by Ali266. Visitors can directly observe the respective bit rate of either side and the bit rate reduction of Ali266 over x265 under the same subjective quality.
