– If you just want a quick “one‑click” improvement, use HandBrake with the “Fast 1080p30” preset, then tweak a few settings (bitrate, encoder preset, audio). If you want full control, dive into the FFmpeg commands and a few optional post‑processing steps described below. 1. Define “Better” | Goal | What it means for your MP4 | Typical metric / visual cue | |------|----------------------------|-----------------------------| | Higher visual quality | Less compression artefacts, sharper details, smoother motion | Higher bitrate, higher‑quality encoder preset, optional up‑scaling | | Smaller file size | Same visual quality with less data | Better compression (H.265/HEVC, VP9, AV1) or smarter bitrate allocation | | Better audio | Clearer dialogue, balanced volume, no hiss | Higher audio bitrate, AAC/Opus, normalization | | Compatibility | Play everywhere (mobile, web, TV) | H.264 (AVC) baseline/ main/ high profile; MP4 container | | Future‑proof | Ready for HDR, 10‑bit, higher frame‑rates | H.265/HEVC, AV1, VP9, 10‑bit depth, HDR metadata |
