TV
Analog television, CRT and broadcast distortion
Simulates analog television defects with scanlines, horizontal/vertical instability, skew, noise and a rolling bar.
TV
DaVinci Resolve · Fusion
TV combines several CRT/VHS/broadcast artifacts in one stylization node, making it faster to build an old-monitor or damaged-signal look.
Overview
What TV does
Controls define the geometric signal instability: scanline density, horizontal and vertical displacement, skew, amplitude, frequency and phase offset.
The Noise section adds interference texture, while Roll Bar creates a broad moving band associated with poor synchronization between camera, monitor or signal timing.
Subtle values create a believable display treatment; extreme values turn the node into a glitch effect. Text and interface graphics should always be checked for readability after the treatment.
Mental model
Think of TV as an unreliable analog display inserted between your clean image and the viewer.

Inspector
Important parameters
Start with these controls before reaching for more complicated workarounds.
Horizontal
Adds horizontal signal displacement or jitter.
Vertical
Adds vertical instability.
Skew
Tilts or shears the signal distortion.
Amplitude
Controls the strength of periodic geometric distortion.
Frequency
Controls how often the distortion pattern repeats.
Offset
Shifts the phase of the distortion and can be animated.
Power
Controls noise intensity.
Size
Controls noise structure size.
Random
Varies the noise pattern.
Bar Strength
Controls the visibility of the rolling bar.
Bar Size
Sets the width of the rolling bar.
Bar Offset
Sets or animates the rolling bar position.
Practical setup
A reliable workflow
- 1
Start with low Scan Lines and small signal displacement.
- 2
Add only enough noise to sell the analog character.
- 3
Animate Offset or Bar Offset so the defect feels alive.
- 4
Protect important text with a mask or reduced blend.
- 5
Check the final compressed output for scanline flicker.

Troubleshooting
Common mistakes
Using maximum noise and making text unreadable.
Keeping all offsets static so the effect feels like a still texture.
Making scanlines so fine that they alias after delivery compression.
Production notes
Practical tips
For a soft CRT feel, add a small Glow after TV.
Animate defects in short bursts rather than continuously.
Use a separate clean branch when client logos must remain legible.
