Two different pro-video editing software companies have released new plug-in versions for Final Cut Pro X and other editors that bring new abilities to their respective platforms. Singular Software has updated its PluralEyes clip-syncing program for FCP X, while FxFactory plug-in developer Nattress has added Levels and Curves, a filter pack that lets users color-grade in the film log, to FCP X and earlier versions, along with Motion and Adobe After Effects.
