MOV to ALAC: the audio-stream extraction route explained
Converter.now selects the audio stream in MOV, leaves the picture stream out, and encodes that sound as ALAC. The result is audio, not a silent 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. ALAC output preserves decoded samples through Apple lossless coding while relying on an MP4-family container for channel configuration, timing, and tags.
Decoded from a QuickTime container written here with H.264 video and AAC audio. Encoded to Apple Lossless Audio Codec frames that preserve decoded samples while reducing PCM storage.

MOV source facts versus ALAC output requirements
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 ALAC audio format cannot safely promise
An elementary or unfamiliar ALAC container may have weaker player support than ALAC inside M4A, and tags can move.
How the ALAC writer handles this route
Apple Lossless Audio Codec frames that preserve decoded samples while reducing PCM storage is what gets written, labeled as audio/x-alac. Whether that actually opens depends on the receiving application, not on the file extension.
Checking the ALAC result before you trust it
Record the MOV evidence before conversion
Scrub the timeline and verify frame size, frame rate, audio sync, color, and target-app playback.
Test the ALAC file in its receiving workflow
Verify lossless decoding, container, sample rate, bit depth, channels, duration, gapless playback, and metadata.
Deciding when MOV to ALAC is the right conversion
Choose this route to deliver dialogue, music, or a soundtrack to a system that accepts ALAC; keep MOV when its pictures, captions, or visual timing still matter.
What changes between the MOV model and the ALAC deliverable
- Timed frames possible in MOV cannot remain an animation in ALAC; verify which frame or static rendering was used.
- MOV and ALAC use different metadata conventions, so application-specific fields should be treated as optional until verified.
