    Large dynamic range is a good thing, in audio and video. There are a number of ways to reduce dynamic range, if you really need to. Expanding dynamic range after capture is possible, too, but more fraught.

    Shannon information theory gives us ways to perfectly reconstruct the lower range version from an expanded range version, but it also guarantees that reconstructing the higher range version from a reduced range version cannot be perfectly accurate across all inputs. (Assuming a fixed output range capability.)

      Large dynamic range is a good thing, in audio and video.

      a good thing for accurately reproducing the original signal.

      But many people watching a show at home would like to just watch the damn movie without anything being particularly loud or resorting to subtitles. Decent range compression achieves that. Applying information theory to a Sunday night movie is stupid.

      I’m also here to support dynamic range. I don’t want the volume “normalized”, I want loud louds and quiet quiets.

        Then there should be a special setting for you. The rest of us normies hate the current state of affairs. Let me hear the dialogue, for fuck’s sake.

        I shouldn’t have to request closed caption subtitles at the cinema because movie producers are wanking each other off about how you need high dynamic range.

        I really think they need to produce 2 different mixes, since most cinemas I’ve been to, it’s been awful in recent years.
