Convert XviD to Android Video — Free Online Converter

XviD is the open-source MPEG-4 Part 2 Advanced Simple Profile video codec that dominated internet video distribution from 2002-2008, with files almost universally packaged in AVI containers at the iconic 700 MB CD-R size. The Android Video device preset is a pre-configured FFmpeg profile producing H.264 Baseline Profile video with AAC-LC audio, optimized for smooth hardware-accelerated playback on Android smartphones and tablets.

Android's media framework does not include an MPEG-4 Part 2 ASP decoder — the codec that XviD implements. While some third-party Android players like MX Player include software decoders for XviD, the performance is poor with dropped frames and high battery consumption. Converting to the Android preset enables hardware-accelerated H.264 decoding for smooth, efficient playback.

XviD AVI files face two compatibility barriers on Android: the MPEG-4 Part 2 ASP codec is unsupported by Android's hardware video decoder, and the AVI container lacks the streaming-friendly structure that Android's media player expects. The Android preset solves both problems by re-encoding to H.264 Baseline in an MP4 container — the combination guaranteed to play smoothly on every Android device.

The codec upgrade from MPEG-4 Part 2 to H.264 also improves compression efficiency by approximately 40%. A 700 MB XviD file can be re-encoded to an Android-optimized MP4 of roughly 400-500 MB at equivalent or better visual quality, saving valuable phone storage.
