MOD is the pioneering Amiga Module tracker format from 1987, embedding instrument samples and pattern-based sequencing data in a single compact file. Born from the Commodore Amiga's Ultimate Soundtracker, MOD introduced the world to sample-based synthesis where short 8-bit digitized sounds are pitched, looped, and sequenced across 4 channels through effect commands like portamento, vibrato, and arpeggio. This format powered the demoscene, early game music, and an entire generation of computer musicians who composed by placing notes on a grid rather than recording performances.
AVI (Audio Video Interleave) is Microsoft's venerable multimedia container format, introduced with Video for Windows in 1992. Converting MOD to AVI produces an audio-only file wrapped in a video container — there is no video track, only the rendered tracker audio packaged within AVI's RIFF-based structure. This is useful when a workflow or platform specifically requires AVI input but the content is purely audio, such as legacy video editing software, certain industrial media players, or presentation systems that only accept AVI files.
Some legacy video production pipelines and industrial media systems exclusively accept AVI as their input format, even for audio-only content. Corporate presentation systems, digital signage controllers, and older video editing suites like VirtualDub may require AVI input. Wrapping rendered MOD audio in an AVI container satisfies these requirements without adding unnecessary video data, keeping file sizes small.
Retro computing enthusiasts creating multimedia presentations about the Amiga era or the demoscene often need audio in AVI format for their video projects. By converting MOD files directly to AVI, they can import the tracker music into their editing timelines without an intermediate conversion step. The AVI container's simplicity and near-universal support across Windows media tools makes it a practical, if somewhat dated, choice for these workflows.
FFmpeg renders the MOD file through its module decoder, synthesizing the tracker's pattern data and sample bank into continuous stereo PCM audio. Since the target is AVI (a video container), the output contains only an audio stream with no video track. The audio is encoded using a codec supported within AVI's RIFF structure — typically PCM (uncompressed), MP3 (MPEG Audio Layer 3), or AC3. The RIFF/AVI header declares the audio stream with proper format tags (wFormatTag), and the interleaved chunk structure contains 'movi' chunks with audio data frames. Some AVI players may display a black screen or blank window since no video track exists, but the audio plays correctly.
The audio quality depends on the codec chosen within the AVI container. Uncompressed PCM in AVI preserves the full quality of the MOD rendering (identical to WAV), while MP3 encoding introduces standard lossy compression artifacts. Since the source is MOD (8-bit samples, limited frequency content), even MP3 at 128 kbps within AVI produces transparent results. The video container adds no degradation — it's merely a wrapper. Note that the rendered audio will only be as good as the MOD renderer's output: interpolation settings, stereo separation, and filter emulation all affect the pre-encoding quality.

MOD to AVI wraps rendered tracker music in a video container for compatibility with systems that require AVI input. The output is audio-only — no video track is generated, keeping the file compact while satisfying format requirements.
