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

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?

    Are there ways to obtain and refill this pallete of smells and connect them to a home cinema? I guess it would work if you have the hardware and the juice for it.

    I imagine dragon’s breath is not unlike a coal furnace, or a chain smoker.

      In a software level, it is easy to time effects like smells in a video file thanks to the information i found. The hard thing is to program the hardware.
