I got my hands on MPEG-V standard documents which lets me inject “SEM” (sensory effect metadata) inside .mp4 files which would let me program real world stuff on cues like lights, chair movements, water sprays, etc. So literally if I had a NAS with a hoard of movies and bought the right equipment, i could make 4DX at home.

There’s an effect description named “scent”, which would, obviously, spray some aromatizer or something in the room. I checked out the standard list of scents that can be applied. There are scents like rose, lavender, mint, apples, mixed herbs, but i came across an interesting one which is the one i’m asking for.


  Scent of dragons breath
  Describes the scent of dragons breath

Maybe this is a weird reason to ask this… I really want to know out of curiosity if this “dragon breath” would be some specific mix of herbs or incense or any kind of room spray. I sense it would kind of be an artificial scent… but idk… really… Would it really work if i coded a “Home 4DX” version of the Hobbit movies?

    This is the real answer. Sulfur Dioxide would basically eliminate any other odors. I’m thinking ozone would be a possible addition, along with whatever that metallic smell is, but nothing biological, no rot, etc.

        If dragons aren’t real, how come you see them in popular media so much? where do the film makers get them? Oh, they used a computer to make them?

        Sounds like dragon denier talk

          This reminded me of an interesting fact I heard like 15 years ago: apparently, dragon-like animals show up in folklore across the world in areas with no native reptile species often enough to be considered an anomaly.

            Hmm. What areas? AFAIK they’re on all the same continents as humans, and a few species get as far north as places like Canada. I guess Ireland famously has no snakes, so maybe there. I’d expect northern Canada and Ireland could both get dragon myths by import from distant lands.

            So, that’s my attempt at an explanation.

              It was 15 years ago or so that I heard that in a TV show, so I don’t really remember any specifics, but I think it would mostly be isolated islands and the like, as I think Hawaii is another place with no native reptile species. Imported myths from other places would be my guess as well.

        Then I guess we also don’t have to think about how they sound or look like, since they are not real no one will want to use that information…

          The point is that it can be whatever we want it to be! It’s fire magic!

          Admittedly, I was just being tongue in cheek in the first place
