Boris FX has released the Boris Continuum Units family of visual effects plug-ins, which makes filters from its Continuum Complete collection available separately.

The first three Units are available immediately: Pan and Zoom for documentary-style animation, UpRez for resizing of image clips from SD to HD, and Chroma Key for pulling keys.

Pan and Zoom provides documentary-style Pan and Zoom techniques made popular by Ken Burns' documentaries. The filter includes a setup mode offering on-screen controls for the size and position of the zoom region, along with the anchor point and a preview area that shows a rendering of the final result. Both manual keyframing and automated workflows are supported. The Pan and Zoom Unit offers image sampling techniques with edge detection for smooth animation and high-quality image detail.

UpRez is designed for conversion of SD footage to higher-resolution HD formats. The UpRez filter employs image sampling techniques with edge detection, providing a final result that cannot be achieved by scaling and standard post-processing methods, according to Boris FX. This Unit also includes an Optical-flow based Deinterlace filter for converting interlaced SD material to progressive scan format.

Boris FX says that the Chroma Key Unit automates creation of precise keys with a minimal amount of adjustment. In addition to the BCC Chroma Key filter, complete with Spill Suppression, this Unit includes a Light Wrap tool for the most natural-looking composites, Color Match and Grain Match tools for seamless foreground composites, and a Matte Choker tool for cleaning up the most challenging keys.

Each Boris Continuum Unit is compatible with Adobe After Effects, Adobe Premiere Pro, Apple Final Cut Pro, and Apple Motion. Pan and Zoom is available for $199 (around £106), UpRez $99 (£53), and Chroma Key $299 (£160). Customers who purchase a Boris Continuum Unit may credit the price of the Unit towards the full Boris Continuum Complete plug-in suite at $895 (£480). Additional Boris Continuum Units will be released in the winter of 2008.
