This new version includes a fast processing mode, that allows for significantly faster model building. Creating a color correction model at the default settings (using 10 color spaces) now only takes up to 2 minutes, independent of the frame resolution, while creating a single space model only takes up to 10 seconds. The single color space model is now available by setting the number of color spaces to 1.
