Turn ordinary footage into a picture on a curved tube screen. Every setting works per frame, so the effect holds steady through camera moves and cuts, while the static changes on every frame.
Tube geometry
Barrel Curvature bends the picture outward from the center, the way the convex glass of a CRT bowed the image. The corners fall outside the source frame and turn black. Vignette darkens toward the edges on top of that, falling off more steeply close to the rim.
Scanlines and the phosphor mask
Scanlines darken two rows out of every three, by up to 60%. The phosphor mask splits each group of three columns into a red, a green, and a blue stripe. Both patterns are three pixels wide in the exported frame, so the output size changes how they read.
Play the result at its own size where possible. A player that scales a three-pixel pattern by an uneven factor turns it into moiré bands that were not in the file.
Color bleed, static, and glow
Color Bleed shifts red one way and blue the other, by up to 1.5% of the frame width, which gives edges the fringing of a misconverged tube. Static Noise adds grain to every pixel. Phosphor Glow blurs a copy of the frame and screen-blends it back, so bright areas spill light into their surroundings.
Export time
The CRT step costs roughly 100 ms per 720p frame on one core. The export spreads frames across the processor’s cores; a dual-core laptop renders about 10 frames per second at 720p, a third of real time for a 30 fps clip. Choose 1080p for finer lines and expect about twice the export time.
