Just for practice (because Lord knows I need it) I'm trying to emulate the title from the TV show, "Supernatural."

I've created a solid, added and animated fractal noise, used Hue/Saturation to make red and black clouds, added a text layer with the word "testing," applied an alpha track matte to the solid and animated the position of the text layer - quick, single frame jumps to the left and right and z.

There's also a vertical glow or blur (I think it's a glow) going on, but only on some of the letters, some of the time. Obviously I can animate glow radius (I say obvious like I'm an old pro - I think it's cool as heck that I've figured that much out without a book showing me how, and I know this is probably among the easier things to do), but I can't figure out how to make only certain letters glow, or - to be more true to the actual titling - half of the word.

I tried duplicating the text layer, masking it and dropping that underneath everything, but that has some weird results. Actually, I just stopped writing this post for a second and jumped back in, and maybe I'm on to something with the duplicate text. Animating the glow and an inverted, subtractive mask seems to do the trick.

Looks like there's a light or two applied to this thing, as well, so I'm gonna play around with that. Lights and cameras are a little tricky for me, so far, so I guess i'd better learn to get comfortable with them.

i'd try creating a layer with some animated fractal noise - set the blockiness so that the size of blocks is similar to the size of the letters, then use that layers as a track matte for an adjustment layer which has your blur / glow effect.

Thus your fractal will drive the opacity of the effect.

i've not tried this yet...but its certainly something i would try.

You might also look into text animators. Just based on your description, I could see a duplicate text layer with random wiggling per-character blur being very useful here. Or even position wiggling with motion blur.

Check this out.

Very handy when trying to recreate a random glow / blur / whatever you want effect using...wait for it...cell pattern.
