I want to create the typical light wall effect, that is often seen in music videos. But not only the wall. I want to display text letters using those flash lights.
Probably I'm missing the right keywords as I did not find a tutorial on this yet.
I'm aiming for something similar to this template: http://videohive.net/item/lights-flashing-3/5882600?WT.ac=item_more_thumb&WT.z_author=HK_graphic
Of course I could just buy it, but I especially want to learn while creating.
So, should I create a layer mask from text, and let eg a flashlight wall footage shine through? Or could I as well create a single flashlight (or take footage), and arrange it in a way that it will form letters?
How can this be done?
