Shift the red, green, and blue channels slightly out of line, so color fringes appear along the edges, like a lens flaw or a digital error.
Glitch transitions, tech and game ads, cyberpunk music videos, a beat-synced shock, and an old-lens feel.
You can put "chromatic aberration, RGB split at the edges" in the prompt, but to control strength and timing it is easier to apply it in editing. In ffmpeg, rgbashift=rh=-6:bh=6 moves red 6 pixels to the left and blue 6 pixels to the right. To turn it on for just a few frames on the beat, add enable='between(t,1.0,1.2)'. In Premiere Pro and After Effects, duplicate the clip, split the color channels, and offset their positions a little. If you only want a lens feel, 1–2 pixels is enough. Don't apply it to captions or logos.
Split the color channels slightly for a lens-fringing, glitchy edge: ffmpeg -i in.mp4 -vf "rgbashift=rh=-4:bh=4" -c:a copy out.mp4. Use 2 to 4 pixels for subtle fringing and 10 or more for a glitch hit, and enable it for only a few frames if you want a quick pulse.
