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?
Well that’s very interesting. I’m guessing this is a proprietary scent that got added to the standard by whoever from the industry.
If I was designing it, it would definitely be fire-y. It would be a bad smell if I was being realistic, full of lizard bile sort of smells mixed in with partial combustion products, but nobody wants to be immersed in that. So, I guess the question is what sort of fire is dragon’s breath?
It’s supposed to be pretty hot, so maybe it’s a metal sort of fire, but then again you don’t really see that in the natural world. Acetylene and friends could do the same, although I’m not sure what that smells like exactly. Maybe I would split the difference between organic and metallic and go with a burning beeswax/hot metal combo, which shouldn’t be too gross.
