I am currently interested in how (what program to use) to make this effects of lighting and animated aura in the following video.
Snapshot of video:
This whole effect is what Riot Games uses for their log in screen for a game called League of Legends. (The video is actually of a character from the game, which is why I mention it)
All of that having been said, the files Riot Games uses in the end are
It's really not a black and white question, there's tons of software out there to do an effect like this. If you want an exact process only the person who made it can tell you but hopefully this is a good starting point for you.
It was more than likely done in After Effects. Chances are they probably used a 3rd party plugin for the light effects as AE hasn't got the greatest selection. My guess is that they used Red Giant's Trapcode. Trapcode is very industry standard for motion graphic artists.
