Scale compositing node

Changes the resolution of the image.

All

Parameters

Local variables

This operation changes the resolution of the image. The contents of the image are scaled appropriately. The aspect ratio may be optionally preserved.

Scale does not affect the cook resolution of its Inputs.

Note

As Scale affects the resolution of the image sequence, its parameters cannot be animated (if animation is desired, use a Transform COP’s scale parameter).

Parameters

Scale

Specifies the scaling method:

To Resolution	Scales to the specified number of pixels.
To Fraction	Scales to a fraction (e.g. 0.5 = 50%)
To Aspect Ratio	Scales to a given Pixel Aspect ratio.
To Second Input’s Resolution	Scales to match the resolution of the second input.
To a Fraction of the Second Input	Scales to match the resolution of the second input scaled by a fraction (e.g. 0.5 = 50%).
To Second Input’s Aspect Ratio	Scales to match the second input’s aspect ratio.

Image Size

Specify the size the image should be scaled to (in Pixels).

Image Fraction

Specify the size you d like to scale the image as a fraction (e.g. 0.5 = 50%).

Pixel Aspect

Pixel Aspect is the ratio of the width to the height. Specify the pixel aspect ratio to scale the image by here.

Preserve Aspect Ratio

When enabled, it preserves the ratio of the image width to height when scaling.

Image Filter

Specifies the type of filter to use when scaling. The Box filter is the fastest; for almost all uses, the Gaussian is the best choice; use Catmull when you need some-thing a bit sharper than Gaussian.
