M1V files store raw MPEG-1 video elementary streams — the bare video bitstream without container overhead, audio, or synchronization metadata. This format was common in VCD production workflows and early MPEG-1 encoding pipelines from the 1990s. AIFF (Audio Interchange File Format) is Apple's uncompressed PCM audio format, the standard for professional audio production on macOS, storing raw samples at CD quality (44.1 kHz, 16-bit) or higher.
Attempting M1V to AIFF conversion only succeeds if the .m1v file has been non-standardly muxed with an audio stream. True M1V elementary streams contain zero audio data, making audio extraction impossible without a companion audio file.
If a .m1v file does contain embedded audio (from non-standard muxing or misnamed program streams), extracting to AIFF produces an uncompressed, lossless representation of the audio. AIFF is the preferred format for importing audio into professional macOS DAWs like Logic Pro, GarageBand, and Pro Tools.
Uncompressed AIFF from an MPEG-1 source provides a clean starting point for any post-production work — noise reduction, equalization, or mixing — without accumulating additional codec artifacts during editing.
FFmpeg scans the M1V file for audio elementary streams. If found (typically MPEG-1 Layer 2 at 128-224 kbps), it decodes the compressed audio to PCM and writes it as signed 16-bit big-endian samples in the AIFF container. Sample rate is preserved from the source (usually 44.1 kHz or 48 kHz). The resulting AIFF file is approximately 10 MB per minute for stereo CD-quality audio. If no audio stream exists, the conversion fails.
AIFF output captures the full fidelity of what the MPEG-1 Layer 2 codec preserved — no additional quality loss occurs during the decode-to-PCM step. However, quality is fundamentally limited by the original MP2 encoding. A 192 kbps MP2 track decoded to AIFF will sound identical to the MP2 source, with the benefit that subsequent processing introduces no further codec degradation.

M1V to AIFF conversion serves the niche case of extracting non-standard embedded audio to uncompressed format for macOS production workflows. Standard M1V video-only files cannot produce AIFF output.
