Audio-stream extraction: how MOV becomes AIFF
Only the audio stream inside MOV is pulled out - The picture stream is discarded entirely - And encoded as AIFF. What comes out is genuine audio, never a muted copy of the video. QuickTime MOV input uses atom-based track and sample tables, including edit lists, rotation, color labels, timecode, chapters, and auxiliary media. AIFF delivery stores waveform samples in an interchange-oriented chunk structure, commonly using big-endian PCM with explicit precision, rate, and channels.
Decoded from a QuickTime container written here with H.264 video and AAC audio. Encoded to Apple's chunk-based Audio Interchange File Format commonly carrying big-endian PCM samples.

Reading MOV correctly and satisfying what AIFF expects
What can fail when QuickTime Movie is interpreted
MOV support varies outside Apple and editing software, while source captions or extra tracks may not be retained.
What AIFF audio format cannot safely promise
AIFF files can be large, and tags, loop points, or uncommon sample precision are not handled uniformly.
How the AIFF writer handles this route
Apple's chunk-based Audio Interchange File Format commonly carrying big-endian PCM samples is what gets written, labeled as audio/aiff. Whether that actually opens depends on the receiving application, not on the file extension.
Acceptance evidence for the converted AIFF
Record the MOV evidence before conversion
Scrub the timeline and verify frame size, frame rate, audio sync, color, and target-app playback.
Test the AIFF file in its receiving workflow
Compare sample rate, bit depth, channels, duration, peaks, tags, and loop markers in the target audio editor.
When to actually choose MOV to AIFF
Take this route when only dialogue, music, or a soundtrack needs to reach a AIFF-accepting system; hold onto MOV whenever its pictures, captions, or visual timing still matter.
What changes between the MOV model and the AIFF deliverable
- Timed frames possible in MOV cannot remain an animation in AIFF; verify which frame or static rendering was used.
- Treat MOV-specific metadata fields as optional in the AIFF result until you have actually confirmed they survived.
