The RGB displace effect allows you to displace (move) the red, green, and blue color channels separately. This can be used to simulate digital distortions and glitches.
This effect is somewhat similar to Chromatic aberrations, but it doesn’t transform the channels geometrically in any way, and only repositions them.
How it works
RGB displace works by individually displacing and scaling the red, green, and blue color channels. Each channel can be shifted horizontally and vertically, and scaled independently. This creates a separation of colors that can produce interesting visual effects ranging from subtle color fringing to dramatic color separation.
Use cases
RGB Displace is particularly effective for:
- Creating digital glitch effects
- Simulating video signal distortion
- Adding stylistic color separation to images or videos
- Creating psychedelic or trippy visual effects
- Enhancing the impact of motion graphics

Warning
This effect behaves differently with different aspect ratios!
Channel flipping
A lot of the time in Vizzy, you can set the scale of something to -1 to flip it. This also works with this effect and will flip the corresponding channel upside-down!
Glow chaining
Some of our users like to use this effect as part of a glow chain. Moving the red channel up and the blue channel down creates peaks of red and blue at the top and bottom of an image. If then blurred, this creates a very interesting glow effect!
