Bloat 480p -

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.

480p files frequently contain multiple audio tracks (e.g., Dolby Digital 5.1, stereo, commentary) and subtitles in bitmap formats (e.g., VobSub). Each uncompressed audio track can add 300–400 Mbps. For a resolution that is often viewed on small screens or with basic speakers, these additional streams constitute significant 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
