Selective multi-pass encoding for cost-effective video streaming

Tech Papers 2026: This paper presents a content-adaptive strategy, CASE, that predicts whether additional encoding passes would provide meaningful gains using a lightweight mechanism that derives spatial and temporal features from each video segment.

Abstract 

As video streaming scales across platforms, resolutions, and devices, encoding efficiency has become critical to maintaining quality while controlling computational cost and energy consumption. Multi-pass encoding is widely used in streaming workflows to improve compression efficiency, rate-control accuracy, and quality consistency. However, its computational overhead is applied uniformly across all...
