By my estimates that would add up to 4ish GB to the file size per 90 minutes of content
Modern CPUs can downmix and compress audio without a sweat, it doesn't need to be done by the studio.
Agree
The high dynamic range 7.1 audio is already on the disc. What we're wanting is a decent stereo mixdown. Could be 128kb mp3 for all I care. Not like I'll be able to discern a higher bitrate on my tv speakers. That should require 86MB per 90 minutes.
Low dynamic range doesn't need to be low quality though
Looking into it, there’s a range of standards for Blu-Ray in terms of video quality. I doubt there are a ton of discs that can’t afford a few of those 25-50GB. Just spitballing ways to make it approachable rather than say only one way is correct. There’s all sorts of fancy stuff going on with DTS. Maybe they could work compression into part of the standard and just include alternate mixes.
