Restores the original motion that existed before using the Unproject node.

The Unproject/Reproject workflow consists of unprojecting motion derived from a 3D Scene node (effectively stabilizing the motion), painting or compositing on the locked down sequence and then reprojecting back to the original motion.

Go to the Paint/Compositing With Unproject/Reproject tutorial to see how it works.

Transform.

Chooses the filtering method when transforming the image. Mitchell is the default.

The Triangle filter is not the highest quality, but fine for scaled images.

Quadratic is like triangle, but more blur with fewer artifacts. It offers a good compromise between speed and quality.

Cubic is the default filter in Photoshop. It produces better results with continuous tone images, but is slower than Quadratic. If the image contains fine details, the result may be blurrier than desired.

This produces good results with continuous tone images which are scaled down, producing sharp results with fine detailed images.

Gaussian lacks in sharpness, but is good with ringing and aliasing.

A good balance between sharpness and ringing, Mitchell is a good choice when scaling up.
