The iPhone Video preset creates H.264 video at up to 1080p with 192 kbps AAC audio, engineered for Apple's iPhone hardware decoders. Every iPhone since the 3GS contains dedicated H.264 decoding silicon that delivers smooth playback with minimal battery impact. Converting 3GPP files from GSM-era phones into this preset makes them fully native in the iOS media stack — Photos, Messages, AirPlay, and native editing tools all work flawlessly.
iPhones do not play 3GPP files through the native Photos or Videos interface. Third-party players like VLC can handle the format, but they use software decoding which consumes more battery and may stutter on older iPhone models. The iPhone Video preset ensures the output leverages the hardware decoder, providing the best possible playback experience.
Converted files also gain full iOS integration: they appear in Photos with proper thumbnails, can be sent via iMessage (with automatic transcoding for lower-bandwidth recipients), shared through AirDrop, and backed up to iCloud Photos. None of these features work reliably with raw 3GPP files.
FFmpeg transcodes the 3GPP source to H.264 Main Profile with AAC LC at 192 kbps in an MP4 container with moov atom front-loaded. The encoding parameters align with Apple's recommended settings for iPhone playback. Resolution is maintained at the source or scaled to fit standard display ratios.
The re-encoded video faithfully preserves the 3GPP source quality. Low-resolution GSM recordings (176x144 to 352x288) remain low-resolution — the iPhone's high-DPI screen will display them at a small size or with visible pixelation when enlarged. AAC at 192 kbps provides cleaner audio output than the original AMR track.
