In this episode of Red Giant TV, Aharon Rabinowitz walks you through the workflow used to create realistic fire for our film Tempo. He'll be using a combination of real fire footage, Trapcode Particular, and some 3rd Party plug-ins.
Note from Aharon: One thing I did not mention - the particles' life is set to 3 seconds, by default. This worked perfectly for my footage. However, if your footage lasts longer than that, you will need to increase the lifespan of your particles - or they might pop out of existence before they die. Alternately, you may want to lower the life value of your particles if the particle sprites' footage is a lot less than 3 seconds.
