VHS Scanlines
Updated: 24 Feb 2025
Add a VHS scanline effect to an image.
VHS Scanlines
Method #
This node creates a VHS scanline effect by brightening the colours in the image, then generating a tiny matrix of dots and multiplying it against the original image. Useful as a small part of a larger damaged VHS effect.
Parameters
These properties control the core behaviours of the node.
Parameter Details Active
Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Blend Amount
Changes the opacity of the new effect over the original image.
Blend Mode (RGB)
Change how the generated effect blends with the parent image RGB.
Blend Mode (Alpha)
Change how the generated effect blends with the parent image alpha.
Affected Channels
Toggle which of the RGBA channels are affected by the effect.
Intensity
The intensity of the effect that is applied.
Amount
Change how strong the efffect is on the input image.
Scale X
The objects scale along the local x-axis.
Scale Y
The objects scale along the local y-axis.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
