VHS Blur
Updated: 13 Feb 2025
Add a damaged VHS effect to an image.
VHS Blur
Method #
This node creates a damaged VHS effect by blurring the image with a chromatic aberration similar to that of old CRT screens.
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.
Blur Scale
How far the blur should push out. This is multiplied by the distance of the pixel from the center of the image.
Chromatic Blur Scale
Scale the effect of the chromatic blur.
Chromatic Intensity Scale
Scale the intensity of the effect.
Noise Amount
How much noise is applied to the image.
Chromatic Bias R
How much the chromatic blur is shifted towards red.
Chromatic Bias G
How much the chromatic blur is shifted towards green.
Chromatic Bias B
How much the chromatic blur is shifted towards blue.
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.
