MPG files use MPEG-1 or MPEG-2 compression from the VCD and DVD era, pairing the video with MP2 audio. iPhone Video is an H.264 1080p MP4 preset specifically tuned for Apple's A-series chips. iPhones cannot play MPG files natively in the default video player, making conversion essential. The re-encoding from MPEG-1/2 to H.264 also improves compression efficiency by roughly 2x, producing smaller files that play smoothly with hardware-accelerated decoding.
iPhones have dedicated H.264 hardware decoders in the A-series chip that enable smooth, battery-efficient video playback. MPEG-1 and MPEG-2 decoding is not hardware-accelerated on iPhone, meaning any MPG playback (via third-party apps) runs on the CPU with significantly higher battery drain and potential stuttering. Converting MPG to iPhone Video ensures native, hardware-accelerated playback.
FFmpeg decodes MPEG-1/2 video from the MPG (deinterlacing as needed), encodes to H.264 Main Profile Level 4.1 at 1920x1080 with a bitrate of 4-6 Mbps. Audio converts from MP2 to AAC-LC at 128 kbps stereo. The output MP4 uses faststart atoms, a 2-second keyframe interval, and parameters matching Apple's VideoToolbox hardware decoder specifications for optimal iPhone performance.
At 1080p with 4-6 Mbps H.264, the output looks excellent on iPhone screens (5.4-6.7 inches). DVD-quality MPG sources (720x480) will not become HD through conversion — the content looks like DVD quality on a small, sharp screen, which is perfectly acceptable at phone viewing distances. H.264 encoding eliminates the interlacing artifacts common in MPG sources.
