Old Television combines a soft luminance bloom with analogue-style grain. It creates a noisy, retro background rather than applying a filter to an uploaded photograph. Bloom spread controls the light field, noise scale changes the texture, and film grain adjusts the surface detail. Pointer influence adds a local response to movement. Choose the light and dark colours independently, then reduce grain if the effect competes with text placed over the animation.
How this shader works
Old Television combines a soft light bloom with dense analogue grain, like a monochrome screen warming up. It is a noisy, retro background, not a filter for an uploaded photo. Bloom spread controls the light field, Noise scale changes the texture and Film grain adjusts the surface detail. Pointer influence makes the light follow movement.
Tips
- Lower Film grain if the effect competes with text on top of it.
- Set Pointer influence to 0 for a bloom that ignores the cursor.
- Choose Light colour and Dark colour independently, for example a green tint for a CRT look.
- Bloom spread sets how far the light reaches across the frame.
Questions
How do I make a retro TV noise background?
Open Old Television and set Film grain and Noise scale for the look of static. Export it as an HTML file, a React or Svelte component or an MP4 video.
Can I apply this effect to my own photo?
No. Old Television is a generated background and does not take an image.
