What is CRT for DaVinci Resolve?

CRT (plugin name OS CRT) is an OFX that simulates a picture tube: electron beam, phosphor, mask and glass. Scanlines bloom out of highlights. It is not a scanline overlay and not the VHS tape plugin.

How is CRT different from VHS?

VHS is cassette wear: tracking, chroma bleed, snow, dropout. CRT is the display: raster, phosphors, aperture grille or slot mask, glass. Use both if the shot went to tape and then to a tube.

A working tube.

Beam, phosphor, mask and glass. Scanlines bloom. Not a tape look.

Flat plate. Then the tube.

Drag the split. Left is the source. Right is CRT on Clean CRT, Amount 1, curvature still at the v1 default of flat unless you raise it.

Ungraded digital plate, same framing as the tube side

Flat CRT on

Tubes, not filters.

Twenty presets in the plugin. These six sell the range. Wear and Damage is a separate gate, so you can keep the tube and kill the noise.

Beam first. Stripes last.

Other CRT tools draw scanlines. This one has an electron beam, so the line blooms in highlights, phosphors saturate before they clip, and glow is scatter in glass.

Beam

Spot size, scanline height, edge defocus. The raster is the beam, not a repeating overlay.

Phosphor and mask

P22, SMPTE-C, EBU, arcade, P39, amber, P4. Grille, slot, or triad. Pitch in millimetres.

Signal

RGB, component, S-Video, composite, RF. Wear and Damage gates noise, sync, ghosting, crawl.

Where it earns the slot.

Arcade and PVM first. Consumer TV when the story needs composite.

Arcade 15 kHz CRT look on a game or CG plate

240p field. RGB. Drive a little hot. Bloom on the whites.

A monitor, not a gimmick

Broadcast preset. Amount full. Artifacts off. Proof it is not only a dirty look.

Questions

What is CRT?

OS CRT in Resolve. A picture-tube sim: beam, phosphor, mask, glass. Presets from Clean CRT through Trinitron, PVM, arcade, VGA, green and amber mono. Wear and Damage is a separate control.

Is this the VHS plugin?

No. VHS is cassette: tracking, snow, dropout. CRT is the display. Stack them if the story is tape into a set.

What hardware?

v1 realtime is Windows with NVIDIA CUDA. CPU fallback is allowed. macOS Metal is not in v1. OFX needs DaVinci Resolve Studio.

Is it on sale?
