The Persistence of Bloat: Analyzing the Inefficiencies of the 480p Standard in a High-Definition Ecosystem
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. bloat 480p
For 480p, a reasonable average bitrate is 0.8–1.5 Mbps for H.264, or 0.5–1.0 Mbps for H.265. Any file exceeding 2.5 Mbps for 480p should be considered bloated unless it contains high-motion content. The Persistence of Bloat: Analyzing the Inefficiencies of
