Remux from AVI or older containers to MP4 or MKV, discarding obsolete index data.
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. bloat 480p
Older containers like AVI (Audio Video Interleave) have high overhead per frame and lack efficient indexing. Remuxing the same 480p video from AVI to MKV or MP4 can reduce file size by 5–10% solely by reducing container overhead.
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.
Strip unnecessary audio tracks and re-encode essential audio to AAC or Opus at 96–128 kbps stereo. Older containers like AVI (Audio Video Interleave) have
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.
