Convert MP4 to AIFF

MP4 → AIFF. 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. AIFF output contains uncompressed 16-bit PCM audio. Only the first audio track is extracted; the source must contain audio. Video input is limited to 2 GB; audio output to 100 MB.

MP4 → AIFF: Example settings

60 s × 48,000 Hz × 2 ch × 16 bit ÷ 8 = 11.52 MB (PCM)

AIFF: 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.
