In TouchDesigner you can recreate a classic CRT

In TouchDesigner you can recreate a classic CRT distortion effect using simple nodes. Start with a line pop and noise to create the scanlines, then apply a lookup texture using your video to color them. Add a math to scale, and build a 3×3 RGB grid with noise chops to simulate dot crawl. Animate everything with abs time dot seconds for that vintage flicker, blend both signals with a composite, and finish with bloom for a perfect retro vibe.
