Develop an intelligent video processing tool that can automatically downsize high-resolution videos (such as 1080p BRRips) to lower resolutions (e.g., 720p, 480p) while preserving the best possible video quality. The tool should utilize advanced codecs like HEVC (x265) for efficient compression and support for multi-channel audio.
