F4V is Adobe's Flash video container storing H.264 video and AAC audio. The Mobile Video preset creates H.264 480p MP4 files designed for universal mobile compatibility across all smartphone platforms — Android, iOS, Windows Phone, and even older feature phones with MP4 support. This is the safest choice when you do not know the specific mobile device but need guaranteed playback.

The Mobile Video preset uses the most conservative, universally compatible settings: H.264 Baseline Profile at 480p with AAC-LC audio. These settings are supported by virtually every mobile device manufactured since 2010, regardless of brand, operating system, or price point. Unlike platform-specific presets, Mobile Video prioritizes compatibility over quality — making it ideal for mass distribution to mixed device audiences.

The preset outputs H.264 Baseline Profile Level 3.0 at 854x480 with 1-2 Mbps video bitrate. Audio is AAC-LC at 96 kbps stereo / 44.1 kHz. Baseline Profile avoids CABAC and B-frames, ensuring hardware decoding works even on the most basic mobile chipsets. The pixel format is yuv420p with fast-start moov atom. Maximum frame rate is capped at 30 fps for consistent battery-friendly playback.

Mobile Video uses H.264 Baseline Profile at 480p — the absolute safest settings for universal compatibility. Android Video (720p Main Profile) and iPhone Video (1080p High Profile) target specific platforms with higher quality but narrower device support.

It will look acceptable but not sharp on high-resolution phones. For a known modern device, use the Android Video or iPhone Video preset instead. Mobile Video is for when you need maximum device coverage.

Yes. At 480p/1.5 Mbps, a 3-minute video is about 35 MB — under WhatsApp's 64 MB video limit for most countries. WhatsApp may still re-compress the video further.

480p is low for tablet screens. If tablets are in your audience, consider the iPad or Android Video preset at 720p or higher.

Most feature phones with video capability support H.264 Baseline Profile MP4 at 480p. This is the most compatible option short of converting to 3GP.
