Notes
Background
Reformat Node Used As Background
Using a Reformat
node set to the desired frame size allows for the Scanline Render
to output to the desired output size, but with an alpha preserved. This is unlike the use of a solid/texture background, which does not preserve the alpha channel of the Scanline Render
output. Note that the Reformat
node needs to enable filter
> black_outside
to retain the desired output size, otherwise it reverts to the geo content.
