Warner Audio bitrate - Blu-ray Forum

illini2000 · 01-26-2010, 06:54 AM

No idea if this has been brought up and a search for Warner didn't show me anything specific about it. I have noticed the bitrate for Warner's TrueHD is considerably less than other studios. It seems closer to Dolby Digital +. I also noticed the DTS-HD bitrate (around 3mbps) on The Final Destination is less than other DTS-HD mixes I have from Lionsgate and Sony (typically 4 or more mbps). Does anyone know reasoning for this? Even though it may not make any difference, I find it strange their Dolby TrueHD differs from someone like Paramount or any of the Asian distributors.

It's due to a couple of factors. The bitrates are determined by what is needed to faithfully reproduce the original studio sound. It is, also, determined by the settings (ex. 48kHz, 96kHz, 196kHz and whether it's 16-bit, 20-bit, or 24-bit). The combination of the above will affect the bitrates in TrueHD and DTS-HD MA.

Seems for TRUEHD Warner has been encode from 16bit masters. Seemingly they have upped the bit rate to 24bit masters for DTSMA.
