Based on the Iomega REV removable storage system, Grass Valley REV PRO drives and disks are specifically engineered for the demands of video professionals and offer unprecedented price/performance for video recording, editing, delivery and archiving. REV PRO brings workflow security and efficiency to all popular editing systems, including EDIUS Pro, and is a cornerstone of Grass Valley's Infinity Series line of IT-immersed acquisition and workflow products.

REV PRO disks deliver the portability and cost-effectiveness of a video tape with the speed, flexibility, and ease of use of nonlinear, random access media. REV PRO delivers realtime recording and playback with a minimum total sustained data rate of 110Mbps to support a single stream of high-definition (HD) video or two simultaneous streams of standard-definition (SD) video. With a storage capacity of 35GB per disk, REV PRO offers approximately 45 minutes of high-quality HD video or more than two hours of SD video. In addition, REV PRO features enhanced security, providing password protection of content.
REV PRO is ideal for video recording and playback, but it can also do much more, such as project management, content distribution and archiving. Since nonlinear editors view REV PRO disks as hard drives, data can be captured directly onto a REV PRO disk. Both footage and edited pieces can be saved on the same media, along with any associated project files and media assets for complete portability.

The REV technology is unique in incorporating the disk and motor in a sealed cartridge, with the heads and all associated electronics in the drive. This makes the exchangeable disks very cost effective while maintaining very high data rates. The REV PRO disk itself is highly rugged, operating in temperatures from –10ºC to 60ºC (14°F to 140°F). Accelerated ageing tests show a long-term archival life of more than 30 years, and a single disk can perform over one million record/erase cycles.

In addition, REV PRO media and drives are compatible with standard consumer-based REV products. This means when on location, editors can use standard REV products available from retail stores worldwide. However, to benefit from REV PRO’s enhanced performance, password protection, and durability features, REV PRO media and drives are the best choice for video professionals.

Infinity is a complete series of products from Grass Valley designed around the use of standard IT platforms and components to deliver a better workflow for broadcasters. First products in the series include the HD/SD Infinity Digital Media Camcorder and the Infinity Digital Media Recorder, a VTR-like device capable of reading, writing and networking content on standard REV, REV PRO and Compact Flash media. Since REV PRO media offers sustained video rates of 110Mbps, the Infinity Digital Media Camcorder can shoot and record, and at the same time be delivering either the same or different content by file transfer.
