The New Frontier

Galileo Video provides video input, output and effects for the IRIS Indigo (tm) R4000® and Indigo2(tm) desktop workstations. Galileo Video is an integral part of the Silicon Studio (tm) solution for film and video production from Silicon Graphics. Together with Indigo® and powerful Silicon Studio applications, Galileo Video opens up a new frontier in production.

Never before have world-class 2Dand 3D graphics, image processing, digital audio and RISC-based computes teamed with high-quality digital video in a desktop package. This fusion unleashes a galaxy of new videographic capabilities and transforms Indigo into a personal post-production suite.

High-Quality Digital Video

With Galileo's high-quality video input and output, you can use Indigo to create professional video productions.

D1 Option

D1 serial digital component video input and output is available for Galileo as an option. The D1 video channels deliver maximum image quality and allow you to working in an all-digital environment free of generational loss.

The D1 option also provides two additional independent video channels. The additional channels allow you to simultaneously manipulate up to three video input streams (two digital and one analog) and two video output streams (one digital and one analog) for applications such as multi-channel DVE and A/B/C roll.

Real-Time Effects

Real-time processing is designed into Galileo's basic architecture. Galileo's alpha blender and key generator enable on-line editing of many fundamental video effects.

Artifact-Free Output

Galileo helps you combine computer graphics and video without tell-tale artifacts. Galileo's system software drives Indigo's graphics at your choice of NTSC or PAL field rates, film frame rate or graphics refresh rates. This eliminates motion artifacts caused by dropped or duplicated frames when outputting graphics to video.

Galileo also offers selectable filters that greatly improve the quality of your productions. The deinterlace input filter brightens the computer display of interlaced video streams. Similarly, the anti-flicker output filter eliminates distracting interlacing artifacts in graphics recorded to video.

Choice of Sizes

Galileo lets you shape your video to sizes that suit your application.

Indigo Magic (tm) Software

Indigo Magic Media tools help you get the most out of Galileo's advanced capabilities. Indigo Magic tools are bundled with every system, and deliver simple pre-production capabilities.

The Video Control panel lets you manipulate Galileo's rich set of signal controls. Bundled video tools perform rapid "print-to-video" of live computer graphics, "video-in-a-window" display, and single frame input and output. Other tools allow you to quickly create and edit digital image, audio and movie objects and control removable media devices such as CD-ROM and DAT.

You can incorporate all of these objects into interactive digital media presentations with IRIS Showcase (tm) for maximum impact. IRIS InSight (tm) brings you up to speed with accessible on-line documentation.

Altogether, this host of end-use software gives you enormous power on your very first day with Galileo - a truly incredible "out-of-box" experience.

Powerful development interfaces are available as options. These include the Digital Media development Option, ImageVision Library (tm), IRIS Inventor (tm) and the CASEVision (tm) visual development environment. These interfaces enable developers to create the unique applications which help Indigo and Galileo open up the new frontier in video production.
