The Mobile Video preset creates a universally compatible H.264 Baseline MP4 designed to play on any smartphone or tablet, regardless of manufacturer or OS. RMVB files are unplayable on virtually all mobile devices without third-party software. This preset uses the most conservative encoding settings — H.264 Baseline Profile, low resolution, mono audio — to guarantee playback even on the cheapest budget phones common in markets where RMVB was popular.
RMVB has zero native mobile support on any platform. The Mobile Video preset ensures universal compatibility by targeting hardware decoders present in even the most basic smartphones. This is especially relevant in developing markets across Asia where RMVB content is abundant and budget phones are the primary computing device.
Video is encoded as H.264 Baseline Profile Level 3.0 with CRF 24 at 854x480 (480p) maximum resolution. Audio uses AAC-LC mono at 96 kbps. The MP4 container includes faststart for progressive playback. These conservative settings ensure hardware-decoded playback on every smartphone since approximately 2010.
Quality is adequate for phone-sized screens. The 480p resolution and mono audio prioritize compatibility over fidelity. On small screens (4-6 inches), the output looks reasonable — larger screens will show visible compression artifacts.

The RMVB to Mobile Video preset is the safest conversion for reaching the broadest possible mobile audience. It sacrifices quality for universal compatibility — the right tradeoff when you can't control the playback device.
