fractal noise with an animated mask and some glow features
or just get a can of wd-40 and a green screen. light a match, spray it. film it (stongly recommend HD…you need the most pixels as possible). other things work too, you catch my drift. Don’t spray it for longer than a few seconds or the flame could go back into the can and blow up in your face. BE CAREFUL. If the green screen doesn’t work right shoot it on solid black and use the appropriate matte. BELIEF.com used fireworks on a solid black background for some of their stuff, and it came out very well. Don’t forget your lensflare and other color effects to simulate the color of the flame around onto other objects.
I’d use particular just because I’m comfortable with it — and I don’t have access to a studio where I could create mock-flamethrowers. Its up to you though. Is it a moving firebreathing or a still firebreathing?
