RGB Glitch or RGB Offset
on Jul 21, 2016 at 11:44:22 am

Hello, :)

Every video that I have watched to how to make RGB glitch or RGB offset effects shows that you need to make 3 layers, first red then green and then blue and change positions... But is there any way to offset colors without making different colored layers?

Thanks!

Best regards,
DADA

There is no way doing it without third-party plugins?

Not in a single layer.

You can, but only with one color fringe. For example you can try this:

1. Apply Effect > Channel > Shift Channels
2. Set Take Green From and Take Blue From to "Full Off"
3. Add Effect > Distort > Transform and shift the image around using position
4. Add Effect > Channel > CC Composite and set it to screen
5 Add another Transform effect and shift the image back so it mostly fills the screen

That'll leave you with a red fringe. While it's not exactly the same as shifting the three channels, it has a unique look.

You can also add an expression to the second Transform's position like this:

pos = effect("Transform")("Position");
x = pos[0] - 1830;
y = pos[1] - 2442;
[value[0]-x,value[1]-y];


Reset the first Transform in the stack and change 1830 and 2442 to the original x and y position of the first Transform. That way when you move the first transform around, only the fringe layer shifts around. I hope that helps. I feel like there's got to be a way to get all three to fringe, but I can't figure it out.
