subPixel
Turns on quality control.
• 0 = low quality
• 1 = high quality
If the new width or height is not an integer (either because it was set that way, or
because of a proxy scale), you have a choice to snap to the closest integer (subpixel
off ) or generate transparent pixels for the last row and column (subpixel on).
Zoom
The Zoom node resizes the image to a given resolution.
Parameters
This node displays the following controls in the Parameters tab:
xScale, yScale
The scaling factor, for example, .5 = half resolution, 2 = twice the resolution.
filter
The method to use to scale the image. For more information, see Chapter 28, “Filters.”
subPixel
Turns on quality control.
• 0 = low quality
• 1 = high quality
If the new width or height is not an integer (either because it was set that way, or
because of a proxy scale), you have a choice to snap to the closest integer (subpixel
off ) or generate transparent pixels for the last row and column (subpixel on).
Remastering to a Different Resolution With Proxies
You can remaster your scene’s resolution using proxy images. As an example, you can
load NTSC and PAL images simultaneously, with one set as a proxy image. With the
proper scaling factors, the scene can be reset to the other resolution by switching the
proxy set.
For more information on working with proxies and high-resolution images, see
Chapter 3, “
Adding Media, Retiming, and Remastering .”
