Video Container

What Is MOV?

MOV is Apple's QuickTime video container format. It holds video, audio, and metadata together in a single file and is the default recording format for iPhone, iPad, iMovie, and Final Cut Pro. QuickAudioConvert can extract the audio track from a MOV file and save it as MP3, WAV, M4A, AAC, OGG, or OPUS.

Key facts

Type: Video container (audio extraction)
File extension: .mov
Developed by: Apple (QuickTime, 1991)
Typical audio: AAC (most files) or PCM (professional)
Common sources: iPhone, iPad, iMovie, Final Cut Pro
FLAC output: Not offered (source audio is typically lossy AAC)

What MOV is

MOV is a container format — a wrapper that holds separate video and audio streams in one file. Developed by Apple as part of QuickTime in 1991, it became the native format for Apple's video ecosystem. When you record a video on an iPhone, edit a timeline in iMovie, or export from Final Cut Pro, the result is a .mov file.

MOV is closely related to MP4: both use the ISO Base Media File Format (ISOBMFF) specification and contain compatible audio and video codecs. A file saved as .mov and a file saved as .mp4 can often be renamed to the other extension and still play correctly — the difference is mostly metadata and compatibility conventions.

What audio is inside a MOV file

The audio codec inside a MOV file depends on how it was created:

AACThe most common case. iPhone and iPad record audio as AAC at 128–192 kbps. iMovie and Final Cut Pro exports typically use AAC as well. AAC is a lossy compressed codec — extracting to a higher bitrate cannot improve quality beyond the original.
PCM (uncompressed)Professional MOV files — such as those captured with external audio recorders, high-end cameras, or Logic Pro — may contain uncompressed PCM audio. These files are lossless. Extracting to WAV from a PCM MOV is a true lossless operation.
MP3 (rare)Older QuickTime files occasionally contain MP3 audio tracks. Uncommon today but handled correctly by the converter.

Common sources of MOV files

—iPhone and iPad video recordings (Camera app default format)
—macOS screen recordings (QuickTime Player)
—iMovie timeline exports
—Final Cut Pro exports
—Older digital cameras with QuickTime support

Choosing an output format

MP3 — for sharing and general use

The most compatible output. Small file, plays everywhere. 192 kbps is the recommended bitrate for music; 128 kbps is adequate for speech, lectures, and interviews.

WAV — for editing

Extract to WAV if you need to import the audio into editing software (Audacity, Premiere Pro, Final Cut, DaVinci Resolve). WAV is accepted universally by DAWs and video editors. Note: if the original MOV audio was compressed AAC, the WAV contains that same AAC-quality audio — it is not an upgrade, but it prevents further re-encoding during editing.

M4A — for Apple devices and podcasting

If the MOV audio was AAC, extracting to M4A keeps the same codec in a pure-audio container — no re-encoding, no quality loss. Ideal for files destined for Apple Podcasts, iTunes, or iPhone playback.

Why FLAC is not offered for MOV

FLAC output is only available from confirmed lossless sources: WAV, AIFF, and ALAC. Most MOV files contain AAC audio (lossy), and encoding lossy audio to FLAC produces a large file with no quality benefit — it stores the AAC-degraded audio in a lossless container, which is misleading and wasteful.

The exception is a professional MOV with a PCM audio track. For those files, FLAC would be technically appropriate — but because the codec cannot be verified at upload time, FLAC is withheld for MOV uniformly. If you have a confirmed lossless MOV, extract to WAV first, then convert WAV to FLAC.

MOV vs MP4

For audio extraction purposes, MOV and MP4 behave identically. Both are container formats that most commonly carry AAC audio. Both are handled the same way by FFmpeg. If you have an MP4 file, use the MP4 converters. If you have a MOV file, use the MOV converters. The output quality will be the same.

Frequently asked questions

Can I extract audio from an iPhone video?

Yes. iPhone videos are saved as .mov files. Upload the .mov file and choose your output format — MP3 for sharing, WAV for editing, or M4A to keep the original AAC codec without re-encoding.

Why is my MOV file so large?

MOV files contain both a high-quality video stream and an audio stream. The video data accounts for most of the file size. Extracting the audio alone produces a much smaller file — typically 1–5 MB per minute as MP3.

Is MOV the same as MP4?

Structurally similar, but not identical. MOV is Apple's QuickTime format; MP4 is the international standard. Both can contain the same H.264 video and AAC audio codecs. For audio extraction purposes they behave the same way — the converter handles both.

What if my MOV file has multiple audio tracks?

The converter extracts the primary (first) audio track, which is the main audio in almost all cases. Multi-track MOV files from professional workflows may require specialized software to access secondary tracks.
