The only Dolby Atmos master rules readable here are a distributor's: Prime Video requires ADM BWF in a BWF-RF64 .wav (codec DOLBY-ATMOS-ADMBWF), 24-bit 48 kHz LPCM, at most 128 tracks, 118 objects and 10 beds, a matching-locale non-Atmos source with a 5.1 mix, and no M&E, MOS, silent or commentary tracks in the Atmos source. Dolby's own ADM profile PDF could not be reached by producer or curator.
