Frischluft Fresh Curves is a curves-based color correction plugin for After Effects and Premiere Pro. Curves are a versatile and precise color correction tool, and Fresh Curves adds the control and accuracy that the native After Effects version lacks.
On top of the usual RGBA, it adds brightness, saturation and hue channels for more direct control. Relative Curves let you adjust one attribute based on another and include a built-in pre-blur and post-blur curve. Bezier cubic splines with tangent handles give more curve control, and interpolation modes are similar to those in the After Effects graph editor. Invert Curves let you apply a custom gamma curve, do the work, then apply the inverted one so you can work in your own color space.
For accuracy, integrated histograms help you find and modify desired areas and give feedback on your changes. The interface is large and resizeable, with zoom tools for out-of-range float colors and detail work, plus the option to edit or sample values and change the color range. Version 1.14 is a maintenance update; support for Apple M1 Macs arrived in version 1.16.
