WebM is Google's own open media format, and Android supports VP8/VP9 WebM playback to varying degrees across device generations. However, many Android devices handle H.264 more efficiently through hardware acceleration than VP9 through software decoding. The Android Video preset produces H.264 MP4 that is hardware-decoded on every Android device for maximum battery efficiency and smooth playback.
While modern flagship Android phones hardware-decode VP9, many mid-range and budget devices software-decode VP9, causing battery drain and potential stuttering at high resolutions. H.264 is universally hardware-decoded on every Android device manufactured since 2010. Converting to the Android preset ensures the most efficient playback path.
Additionally, Android's media scanner and gallery apps handle MP4 more reliably than WebM for thumbnail generation and metadata display.
FFmpeg decodes VP8/VP9/AV1 video and Opus/Vorbis audio from WebM, then transcodes to H.264 High Profile Level 4.1 with AAC-LC audio at 44.1 kHz stereo. Resolution is preserved up to 1080p. The output MP4 uses faststart for instant playback. For VP9 at 4K, resolution may be capped at 1080p for universal hardware decoder compatibility.
H.264 and VP9 produce similar quality at comparable bitrates for most content. The conversion is primarily for compatibility and battery efficiency rather than quality improvement. At 1080p with CRF 23, the Android Video output looks excellent.
