RGB Glitch or RGB Offset
Posted by Dada Kräuter on July 21, 2016 at 11:44 amHello, 🙂
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,

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 screenThat’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.
