Although spatial quality degradation is well-documented, the relationship between compression intensity and temporal stability remains insufficiently characterized. This paper systematically examines the progression of frame-to-frame coherence errors across different bitrate regimes, utilizing multiple codecs (AV1, HEVC, VP9, H.264) and content types. Our findings reveal that temporal con"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Temporal consistency degrades non-linearly with increasing compression, and sequences with
