Convert MOD to AIFF — Free Online Tool
Extract and convert the audio track from JVC or Panasonic MOD camcorder footage into a high-quality, uncompressed AIFF file. This tool strips the MPEG-2 video and transcodes the audio to 16-bit big-endian PCM — the native encoding Apple uses for lossless audio storage on macOS.

DownloadHow It Works
MOD files are MPEG-PS containers storing MPEG-2 video alongside a compressed audio track (typically AC-3 or MPEG audio). During this conversion, FFmpeg discards the video stream entirely and decodes the compressed audio, then re-encodes it as uncompressed PCM signed 16-bit big-endian (pcm_s16be) wrapped in an AIFF container. Because AIFF is a lossless, uncompressed format, the output faithfully represents the decoded audio signal — though since the original MOD audio was already lossy, the AIFF preserves the quality of the decoded signal rather than recovering anything lost in the original compression.
What Each Flag Does
| Flag | What it does |
|---|---|
ffmpeg
|
Invokes the FFmpeg program — the open-source multimedia processing engine running here as WebAssembly in your browser (FFmpeg.wasm), and available as a desktop CLI tool for files over 1GB. |
-i input.mod
|
Specifies the input file — a MOD camcorder video file in the MPEG-PS container format used by JVC and Panasonic camcorders. FFmpeg auto-detects the MPEG-PS structure and identifies the video and audio streams inside. |
-c:a pcm_s16be
|
Sets the audio codec to 16-bit signed big-endian PCM, which is the standard uncompressed audio encoding for AIFF files. This decodes the lossy compressed audio from the MOD file (typically AC-3 or MPEG audio) and writes it as raw PCM samples in the big-endian byte order that AIFF requires. |
output.aiff
|
Defines the output filename and container format. The .aiff extension tells FFmpeg to wrap the PCM audio in an Audio Interchange File Format container — Apple's lossless audio format widely supported on macOS, in Logic Pro, Final Cut Pro, and professional audio tools. |
Common Use Cases
- Extracting ambient sound or dialogue recorded on a JVC or Panasonic camcorder for use in a Final Cut Pro or Logic Pro audio project on macOS, where AIFF is a native and preferred format.
- Archiving the audio track from old MOD camcorder recordings in an uncompressed format before the original media degrades or the MOD files are deleted.
- Preparing location audio recorded on a camcorder for use in a broadcast or podcast workflow that requires uncompressed PCM audio masters.
- Supplying a clean, uncompressed audio file from camcorder footage to a sound designer or music editor who needs to work without any lossy codec artifacts in their editing chain.
- Converting MOD recordings of live performances, speeches, or events into lossless AIFF files for long-term preservation or CD authoring on macOS.
Frequently Asked Questions
No — converting to AIFF will not recover quality that was lost when the original audio was encoded in the MOD file. MOD files use lossy compressed audio (typically AC-3 or MPEG Layer 2), so any artifacts from that compression are baked in. What AIFF gives you is an uncompressed representation of the decoded audio, which prevents any further quality loss in downstream editing or processing.
AIFF stores audio as raw, uncompressed PCM samples — no compression whatsoever. A MOD file's audio track uses lossy compression (like AC-3 or MPEG audio) that can achieve 10:1 or higher compression ratios. When you decode that compressed audio and write it as uncompressed 16-bit PCM in AIFF, the audio portion alone can be many times larger. For a one-hour recording, AIFF audio at 16-bit/44.1kHz stereo will occupy roughly 600 MB.
No. AIFF is a pure audio format and cannot contain video streams. The conversion extracts only the audio track from the MOD file; the MPEG-2 video is discarded. If you need to keep the video, you should convert the MOD file to a video format like MP4 or MKV instead.
Yes. The default command uses pcm_s16be (16-bit), which is standard CD quality. AIFF also supports 24-bit (pcm_s24be), 32-bit integer (pcm_s32be), 32-bit float (pcm_f32be), and 64-bit float (pcm_f64be). To change the bit depth, replace '-c:a pcm_s16be' in the FFmpeg command with your preferred codec, for example: ffmpeg -i input.mod -c:a pcm_s24be output.aiff. Higher bit depths increase file size but offer more headroom for audio editing.
Generally, no. MOD files store metadata in the MPEG-PS container format, and AIFF has very limited metadata support compared to formats like FLAC or MP4. FFmpeg may carry over basic tags if AIFF supports them, but camcorder-specific metadata such as recording date, GPS coordinates, or scene information embedded in the MOD container will typically be lost during conversion.
You can process multiple MOD files in a loop using your shell. On macOS or Linux, run: for f in *.MOD; do ffmpeg -i "$f" -c:a pcm_s16be "${f%.MOD}.aiff"; done. On Windows Command Prompt, use: for %f in (*.MOD) do ffmpeg -i "%f" -c:a pcm_s16be "%~nf.aiff". This converts every MOD file in the current directory to a separate AIFF file. Note that the browser-based tool processes one file at a time; the FFmpeg command is ideal for bulk conversions of large batches or files over 1GB.
Technical Notes
MOD is a proprietary variant of the MPEG-PS (Program Stream) container used by JVC and Panasonic SD-card and HDD camcorders. The audio stream inside a MOD file is most commonly encoded as Dolby AC-3 (stereo or 5.1) or MPEG Layer 2 audio at 48 kHz. FFmpeg handles MOD demuxing reliably by treating it as MPEG-PS. The output codec pcm_s16be is 16-bit signed big-endian PCM, which is the canonical audio encoding for AIFF — a format Apple designed in the late 1980s, using big-endian byte order (matching Motorola 68000 architecture) as opposed to WAV's little-endian PCM. Because the source audio is 48 kHz (standard camcorder sample rate) and the AIFF output inherits the same sample rate by default, no sample rate conversion occurs unless explicitly requested — this preserves timing accuracy. If you plan to use the AIFF in CD authoring software, you may need to resample to 44.1 kHz using the '-ar 44100' flag. There is no subtitle, chapter, or secondary audio track support in either format, so no data of those types can be lost.
