Digitally composited fire is a common element that comes up regularly in television, film, commercial advertising, and web content. For obvious reasons, it is much safer than dealing with real fire, and generally it is significantly cheaper than dealing with practical live flames, which always includ additional expensive permits and safety staff on set. That is why it’s a must for VFX artists to understand where to get fire elements for use, how to composite them, and how to add that extra lively touch of heat waves coming off the flames.

WHERE TO FIND FIRE ELEMENTS?

Digital fire elements are easy to find. One of the most common fire element packages comes from VideoCopilot.net’s Action Essentials 2. The package additionally comes with other action elements including: smoke, muzzle flashes, bullet casings, explosions, and more. The 720p version is available for only $99.95, and the 2k version is only $249.95.

MotionElements.com is another good resource for purchasing royalty free digital elements a la carte style. A quick search for fire video elements brought up hundreds of results ranging in price and quality. What I like particularly about this site is they also offer 30 FREE elements weekly via email, and occasionally fire elements come at no cost to you whatsoever. Check it out and sign up!

ArtBeats.com operates similar to Motion Elements pay-per-item service. The footage here is generally better, but it also comes with a price. The old adage of “You get what you pay for” is true in this case, and with Art Beats you get the absolute best.

HOW TO COMPOSITE FIRE

To composite a fire element, we first start out with our scene in After Effects CC. Here, I am using a personal stock photo of a pumpkin farm.

From there, I am going to navigate to my Action Essentials Fire element on my computer’s hard drive and drag and drop it into my scene.

To start compositing the fire into the scene, we obviously need to get rid of all the black. To do so, simply right click on the element in your timeline and change the BLENDING MODE to ADD.

From there we want to adjust the SCALE and POSITION to line up the fire where we want it to go. For me, the fire element is a big too long for what I need so I am also going to use the PEN TOOL and create a MASK only around what I need and FEATHER the edge.

Right now the fire still seems a bit flat, so to give it some pop I am going to add a glow. To do that, with your fire element selected in the timeline, go to EFFECT > STYLIZE > GLOW. Increase the GLOW RADIUS to your preference (I went around 150).

In future lessons we will look at adding heat waves and smoke. As they are released, I will also add links to those tutorials here.
