New compositor slashes surveillance video file sizes by up to 40%

Researchers have developed BLUE, a novel pre-encoding compositor designed to significantly reduce storage requirements for continuous surveillance video. BLUE works by maintaining a persistent background seed frame and substituting unchanged background pixels with these seed pixels before encoding. This process allows video encoders to use SKIP macroblocks for the static background, thereby reducing file sizes by an average of 34.6% to 39.4% with minimal impact on foreground object quality. AI

IMPACT Could significantly reduce storage costs for surveillance systems, enabling longer retention periods or higher resolution.
