Convert M4V to ALAC

M4V → ALAC. Source file ≤ 2 GB · Output ≤ 100 MB · audio stream #1 → audio · video → ∅.

MP4 is a video container, not a codec. Its actual video and audio codecs depend on the file. ALAC is lossless audio in an M4A container, distinct from AAC/M4A. Only the first audio track is extracted; the source must contain audio. Video input is limited to 2 GB; audio output to 100 MB.

M4V → ALAC: Example settings

ALAC: Output

Sizes are examples, not guarantees. Container overhead is extra; variable bitrate and image content change the result. Keep the original and compare the output.
