摘要
A system and method provide a video coding system for adaptively transcoding videos based on video coding complexity (VCC). A VCC engine of the system is configured to generate a measure of how difficult to encode a source video based on a trained VCC model. A video rate-distortion modeling engine of the system is configured to estimate a rate-distortion model and a scaling model. The VCC model, rate-distortion model and the scaling model are trained on a video corpus of the system. The trained VCC model, rate-distortion model and the scaling model are used by an adaptive bitrate transcoding sub-system to transcode a source video with an optimized bitrate and visual quality. The trained VCC model, rate-distortion model and the scaling model are further used by an adaptive resolution transcoding sub-system to transcode a source video with an optimized resolution and visual quality.
