To the consternation of some of its fellow Oklahomans, VFX training site Digital-Tutors recently released a meteor sighting video online, which quickly went viral.

The clip sparked a frenzied discussion on Reddit’s front page and made its way onto national and local broadcasts in the USA.

The fake clip has been revealed to be a marketing stunt for a free After Effects tutorial, which has now been released on Digital-Tutors website.

The tutorial teaches artists how to create the lighting effects and tracking techniques that will help them create VFX shots of their own. Other topics covered in the course of the video include creating a meteor tail, setting up light for animation, and painting the moon out of the sky.

“Digital-Tutors has a long history of presenting artists with expert tutorials that move them along in their careers, but this is the first time we’ve released the final video before the tutorial,” said Grant Boudon, director of marketing and PR for Digital-Tutors. “Now that we’ve seen the power of a viral video and both pieces are in place, we look forward to seeing what artists can create with the free training and 1,000s of other tutorials in our training library.”

The training is provided for free with a demo account or a free promotional course account.

Using plug-ins such as Trapcode's Particular and Knoll Light Factory, it goes through the process of how a meteor effect can be created and integrated into video footage.

It also covers the process of creating an alpha matte, tracking footage, creating a meteor effect with Particular and works through a technique for converting 3D camera track into 2D data so it can be used with Knoll Light Factory.

The tutorial also talks about how to add in some lens effects and use animation to add polish to the shot
