Prime Video's public Tech Docs, as archived, ask for fully mixed program tracks only (M&E and MOS removed), 48 kHz audio in the stated L-R-C-LFE channel mapping, and descriptive audio typed as Narration and paired with same-locale dialog. They list validation failures such as wrong channel counts and audio-video duration mismatches over 2.0 s. Neither archived page states a loudness target or true-peak limit, so a loudness number for Prime Video cannot be cited from these public pages.
