M1V is the MPEG-1 Video elementary stream — raw video frames from the 1993 standard at VCD resolution (352x240/288), stored without any container, audio, or metadata. The iPhone Video device preset produces H.264 Main Profile video with AAC-LC audio optimized for iPhone hardware decoding. The conversion adds the MP4 container structure and modern codec that iOS requires for playback.
On the iPhone's 6.1-6.7 inch screen, M1V's low resolution is less prominent than on iPad's larger display. The content fills a proportionally larger area of the viewing experience, making VCD-era video reasonably watchable for short clips and archival viewing.
iOS cannot play M1V files — the format is unknown to Apple's media framework. The iPhone preset converts the raw elementary stream into H.264 MP4 that the iPhone decodes in hardware. The output plays in the Files app, TV app, and all third-party video players without compatibility issues.
The MP4 container also enables features that M1V lacks: seeking via scrubber, duration display, thumbnail generation for the file browser, and AirDrop sharing with other Apple devices. These quality-of-life improvements make the content usable rather than just technically decodable.
FFmpeg reads the M1V elementary stream, decodes MPEG-1 video, and re-encodes to H.264 Main Profile Level 3.1 at the source resolution (352x240 or 352x288). Video bitrate targets 500 kbps-1 Mbps. The MP4 container includes faststart for instant playback. No audio is included unless an external source is provided. The iPhone's hardware decoder handles the output with zero CPU load.
H.264 at 500-800 kbps produces cleaner output than the MPEG-1 source at matching dimensions. On the iPhone's 6.1-inch screen, the 352x240 content is watchable — softer than modern video but clear enough for identifying content and following action. The small screen hides resolution limitations better than larger displays. Files are 30-60 MB per hour.
