how would I get this effect on text or images?

<http://www.apple.com/trailers/newline/bekindrewind/large.html>

I'm referring to the effects on the text that reads, "When all the tapes got erased"
The way the text looks like it's being slightly mirrored below it.
How do you get that purplish/blueish glow around the time-code text in that grainy way?
Also how would you get the text to appear like its being lit up over the non-lit up time-code numbers? (like when you look at a VCR's little screen for the time-code under a light when the screen is off)

Then there are those distortion effects done to the actual footage as jack black first enters the store. How could I best achieve that?

I've got a good start at trying to get the right color of glow/ambience in the text, but I can't get the glow to form that rectangular shape.




I would really appreciate the help

Thanks,
Mac

hey MAc.pal,

whats funny is didn't know that movie is coming soon, and I love the intro thanks for that, LOL.

but here is a tutorial i have viewed but have not tried, Andrew Kramer is on videocopilot.net and he is one cool guru of this stuff.

this video tutorial should give you enough background in creating a similar composition then rendering it out to a background different than he shows but more like the trailer you posted,

anywho, good luck

I went through that frame by frame and noticed that the picture rolling and stuff was obviously just moving a tiled video around and some displacement mapping to make the zigzagged distortion and then white bars of interference overlayed on top.
you could actually see the tiling in the video as it butts right up to the adjoining video tile whereas when real video rolls there is usually more of a black or white border between frames. Most people wouldn't notice that though because its so short and its in motion, I had to freeze frame it to see.

Thanks a lot Tinman that's really helpful.

Arson; thanks, I wasn't sure what kind of distortion, I haven't really worked with that stuff before.


thanks,
