iPhone's hardware video pipeline is built around H.264 (all models) and H.265/HEVC (iPhone 7 and later), with no native MPEG-1 or MPEG-2 hardware decoder. iPhone Video conversion targets H.264 Main or High profile with AAC-LC audio in an MP4 container — the precise format that Apple's VideoToolbox framework hardware-accelerates for smooth, power-efficient playback.

iPhones process H.264 video through a dedicated hardware decoder that uses minimal battery and produces zero dropped frames even during intense scenes. Attempting to play MPEG-1/2 files via VLC's software decoder on iPhone results in high CPU usage, heat generation, and reduced battery life. Additionally, iOS's native Files and TV apps cannot open .mpeg files at all.

Converting MPEG to iPhone Video also optimizes for the phone's specific screen dimensions (from 640x1136 on iPhone 5s to 1290x2796 on iPhone 15 Pro Max in landscape mode) and integrates with AirPlay, AirDrop, and iCloud sharing. The MP4 container with faststart flag enables immediate playback when streaming or downloading.

FFmpeg encodes to H.264 Main profile level 3.1 (for iPhone 5s-7) or High profile level 4.1 (iPhone 8+) with AAC-LC audio. The command uses `-c:v libx264 -profile:v main -level 3.1 -c:a aac -b:a 128k -movflags +faststart -pix_fmt yuv420p`. For modern iPhones, H.265 encoding with `-c:v libx265 -tag:v hvc1` produces 30-40% smaller files at the same quality.

720x480 preserves DVD MPEG-2 quality without upscaling artifacts. For iPhone 12+ with 1080p displays, you can upscale to 1280x720 if the source quality supports it. Never exceed the source resolution.

iPhone 7 and later (A10 chip and newer) support H.265/HEVC hardware decoding. For universal compatibility including iPhone 6s and SE (1st gen), use H.264.

Yes, if you import the MP4 via iTunes/Finder sync or AirDrop. The video will appear in the Photos app with full playback controls, sharing, and editing capabilities.

The converter maintains the original 4:3 aspect ratio with pillarbox (black bars on the sides). This is preferable to stretching, which distorts the image.

Yes. MP4 supports soft subtitle tracks (mov_text format) that display as captions in the iOS video player. Users can toggle them on or off during playback.

Speed depends on duration and output resolution. A 1-hour MPEG-2 DVD file typically converts in 3-8 minutes depending on the encoding speed preset chosen.
