Pixel Stretch

Organic nonlinear subpixel stretching

Stretch the pixels of your footage according to their brightness to create non-linear organic effects with Pixel Stretch.

How It Works

Pixels are stretched on a subpixel precision according to their brightness. The stretching is cumulative for every row or column, which means a pixel offsets all the following pixels on its line. This produces much more organic-looking patterns compared to what you get using simple effects like “line stretch”. The basic effect is similar to what you’d get on an old analog TV, but all the knobs this filter provides give you many more possibilities!

Usage hints

You can replicate the simple “line stretch” effect like by:

  1. adjusting the Stretch Start Offset to the desired row/column
  2. increasing Pixel Stretch and Pixel Size values to maximum

If you want the line stretch to be more organic, try tweaking the Distribution Mode and Range.

  • Use more instances of the effect on the same layer/clip. Alter only the desired part of the image using Stretch Start Offset together with Distribution Mode and Range.
  • Edge Mode set to Transparent with Transparency Feather on are useful for transitions. The same goes for using Shading Opacity with the layer’s opacity.

Pixel Stretch

Available parameters rundown

  • Direction defines towards which edge the stretching occurs.
  • Pixel Stretch. The maximum length by which a pixel can grow. With the default stretch curve, darkest pixels add 0 and the brightest pixels add this value to the final length.
  • Pixel Size. The base size of a pixel. The final pixel size is between Pixel Size and Pixel Size + Pixel Stretch, eg. 1 to 2 in the UI screenshot.
  • Stretch Curve specifies how pixel brightness maps to stretching. The default mode (Linear Ramp Up) doesn’t stretch dark pixels at all and stretches bright pixels by the maximum amount. Linear Ramp Down is the opposite behavior.
  • Stretch Curve Phase. Offsets the values of stretch curve mapping. See the manual (downloaded with the plugin) for a more detailed explanation.
  • Stretch Start Offset. Skips a percentage of the image before pixel stretching starts.
  • Distribution Mode. Defines how pixel stretching spreads over the image.
  • Constant. The stretching occurs over the whole image evenly.
  • Linear Ramp Up. The stretching gradually ramps up from no stretching to the values defined by Pixel Size + Pixel Stretch.
  • Linear Ramp Down. The stretching starts at the values defined by Pixel Size + Pixel Stretch and gradually ramps down until no further stretching occurs.
  • Distribution Range. Defines what percentage of the image should be affected by stretching. Values from 0 to 1 effect from 0 up to 100% of the image width (or height, when stretching vertically). Values above 1 move gradually into infinity. If you use Pixel Size smaller than 1, the image may be repeated when values above 1 come into play. The default value is 2, ie. infinity.
  • Image Shift Phase. To put it simply, it offsets the image in the stretch direction.
  • Image Shift Phase Sync. When shifting the image using Image Shift Phase, the luminosity values can be picked from the shifted image (on) or the original image (off).


Shading refers to overlays shading patterns over the stretched image. Below, the shading parameters.

  • Shading Interval Size. Defines how thick the shading patterns are.
  • Shading Interval Phase. In summary, it offsets the shading pattern.
  • Shading Channel(s). Allows you to select whether shading dims the image (RGB) or the alpha channel
  • Shading Opacity. Specifies how opaque the shading patterns are.
  • Edge Mode. When using starting pixel sizes lower than 1, the stretched image may not cover the whole frame. The edge mode defines how the image should be repeated when this occurs.
  • Transparency Feather. When using the Transparency Edge Mode, edges, where the image ends, may be smoothed using this option.
