Early streaming and archiving often used CBR to ensure compatibility. A 480p video encoded at 2.5 Mbps CBR will have a massive file size, even during static scenes that require far less data. Variable Bitrate (VBR) encoding could reduce size by 40–60% without quality loss. The failure to use VBR in legacy 480p files is a primary source of bloat.

Much 480p content was originally encoded with MPEG-2 (DVD standard) or early MPEG-4 Part 2 (DivX/Xvid). These codecs have compression ratios far inferior to modern standards like H.264 (AVC) or H.265 (HEVC). A 90-minute 480p MPEG-2 video might occupy 4–5 GB, whereas the same content in H.264 at 480p could be 500 MB or less without perceptible loss. The legacy codec overhead is pure bloat. Early streaming and archiving often used CBR to
The digital video landscape has evolved to prioritize resolutions of 720p, 1080p, and 4K. However, the 480p standard (NTSC DVD quality, 854x480 or 720x480 pixels) remains ubiquitous in legacy content, surveillance, and low-bandwidth streaming. This paper introduces the term "Bloat 480p" to describe a specific inefficiency: a video file encoded at 480p that occupies a disproportionately large file size relative to its perceptual quality and information density. This phenomenon arises from inefficient codecs, unnecessary bitrate allocation, container overhead, and the failure to re-encode legacy content for modern compression standards. We examine the causes of this bloat, its impact on storage and bandwidth, and propose mitigation strategies. The failure to use VBR in legacy 480p
