ALAC to MOV: the audio-only container delivery route explained
ALAC audio is what actually exists here, and it gets encoded straight into a MOV media container. No artwork or motion is invented, so the resulting MOV file can carry no meaningful video stream at all. ALAC arrives as losslessly coded Apple audio whose frame configuration, channel layout, sample depth, timing, and MP4-family tags are decoded independently. MOV delivery uses QuickTime track and sample structures suited to Apple and editing workflows, with codec, color, time-scale, chapter, and cross-platform support checked separately.
Decoded media - Apple Lossless Audio Codec frames that preserve decoded samples while reducing PCM storage. Encoded delivery profile - A QuickTime container written here with H.264 video and AAC audio.

Reading ALAC correctly and satisfying what MOV expects
What can fail when ALAC audio format is interpreted
An elementary or unfamiliar ALAC container may have weaker player support than ALAC inside M4A, and tags can move.
What QuickTime Movie cannot safely promise
MOV support varies outside Apple and editing software, while source captions or extra tracks may not be retained.
How the MOV writer handles this route
The verified MOV profile uses H.264 video at CRF 23 and AAC audio at 192 kbit/s.
Acceptance evidence for the converted MOV
Record the ALAC evidence before conversion
Verify lossless decoding, container, sample rate, bit depth, channels, duration, gapless playback, and metadata.
Test the MOV file in its receiving workflow
Scrub the timeline and verify frame size, frame rate, audio sync, color, and target-app playback.
Deciding when ALAC to MOV is the right conversion
Use this route only when the receiving workflow specifically accepts audio inside MOV. It is not a music-visualizer or slideshow generator.
What changes between the ALAC model and the MOV deliverable
- MOV can hold a timed animation, but ALAC has no frames to give it; expect a single still frame unless more source material is supplied.
- Metadata handling differs between ALAC and MOV; do not assume every application-specific field carries across untouched.
