The Mobile Video preset generates H.264 Baseline Profile video at 480p with AAC audio in an MP4 container, targeting the lowest common denominator of mobile device capability. This preset prioritizes universal compatibility over resolution or advanced encoding features, ensuring the output plays on virtually every smartphone manufactured in the last 15 years — from premium flagships to the most basic budget devices.
When sharing video with a diverse audience whose devices you cannot control, the Mobile Video preset eliminates compatibility risk. H.264 Baseline Profile is the one profile that every mobile chipset supports, and 480p resolution displays well on any screen size while keeping file sizes minimal.
The compact file sizes also matter for mobile sharing. A 3GPP clip converted to Mobile Video typically stays well under 5 MB, making it easy to send via WhatsApp (16 MB limit), email (25 MB limit), or even SMS/MMS on networks with strict size caps.
FFmpeg re-encodes the 3GPP source to H.264 Baseline Profile at 480p (or source resolution if smaller) with AAC LC audio at moderate bitrate in an MP4 container with faststart. Baseline Profile is specifically chosen because it requires the least processing power and has the broadest hardware decoder availability.
The 480p preset resolution is higher than typical 3GPP source dimensions, so no quality is lost from resolution changes. H.264 encoding preserves the source quality efficiently. AAC audio sounds cleaner than AMR for speech content. Overall, the output represents the best quality the source can provide in the most compatible format.
