About AIF to AVI Conversion
AIF is Apple's uncompressed PCM audio format from 1988, storing audio in big-endian byte order within an IFF-derived container. Developed for professional use on classic Mac OS, AIF preserves full audio fidelity at CD quality or higher. AVI (Audio Video Interleave) is Microsoft's multimedia container from 1992, designed to hold interleaved audio and video streams within a RIFF structure.
Converting AIF to AVI wraps audio content into a video container. Since AIF contains only audio, the resulting AVI file will be audio-only — no video stream is generated. This produces a valid AVI file that media players will handle as audio, though the video container adds some overhead compared to audio-specific formats.
Why Convert AIF to AVI?
Some legacy video editing workflows, multimedia authoring tools, and industrial control systems accept only AVI files as input. When these systems need to process audio from Mac sources, wrapping AIF audio in an AVI container provides compatibility without requiring the target system to understand the AIFF format. Broadcasting equipment and legacy Windows media servers sometimes mandate AVI for all media assets.
The AVI container also allows the audio to be muxed with a video track later in the production pipeline. By pre-converting AIF to AVI, the audio is already in the correct container for downstream video assembly workflows that operate exclusively with AVI.
Common Use Cases
- Preparing AIF audio for legacy video editing systems that only import AVI files
- Wrapping Mac-originated sound effects in AVI for Windows-based multimedia authoring
- Creating audio-only AVI assets for industrial media players that require AVI format
- Pre-packaging AIF recordings for broadcast automation systems mandating AVI input
- Converting AIF narration tracks to AVI for integration into legacy training video pipelines
How It Works
FFmpeg reads the AIF container's big-endian PCM stream and writes it into an AVI (RIFF) container. The audio can be stream-copied as PCM (preserving lossless quality with little-endian conversion) or re-encoded to MP3, AC3, or another AVI-compatible codec. The resulting AVI file contains only an audio stream with no video track. The RIFF container uses little-endian byte order, so the big-endian PCM from AIF is byte-swapped during the remux if raw PCM output is selected.
Quality & Performance
If the audio is stream-copied as PCM, quality is perfectly lossless — the byte order conversion from big-endian to little-endian does not alter the audio samples. If re-encoded to MP3 or AC3, standard lossy compression quality applies. The AVI container itself introduces no quality degradation regardless of the audio codec chosen.

Tips for Best Results
- 1Use PCM codec (-c:a pcm_s16le) in AVI for lossless audio transfer from AIF
- 2Add MP3 encoding (-c:a libmp3lame -b:a 320k) if file size matters more than perfect fidelity
- 3Remember the output is audio-only in a video container — some AVI players may show a blank screen
- 4For modern workflows, consider WAV or M4A instead of AVI unless AVI is specifically required
- 5Verify the output with mediainfo to confirm the audio stream properties match your AIF source
AIF to AVI wraps Apple's uncompressed audio into Microsoft's video container. The result is an audio-only AVI file suitable for legacy systems requiring AVI format. Use PCM audio for lossless transfer or MP3/AC3 for smaller file sizes.
