Part of the new NEXIO® Global Proxy solution, the NEXIO AMP® PRX Encoder is an optional, integrated media application for the NEXIO AMP® advanced media platform. It enables the NEXIO AMP server to automatically generate low-resolution H.264 MP4 proxy files simultaneously with the baseband ingest of high-resolution video. These proxy files are saved to any standard storage array, where they can be viewed, edited and conformed back to high-resolution with other components of the Harris® NewsForce™ platform. The NEXIO AMP PRX Encoder supports up to two record channels per server.
The NEXIO Global Proxy solution is part of the NewsForce HD/SD news platform. All NEXIO Global Proxy products contribute to a highly efficient low-resolution workflow that:
The PRX Encoder application monitors the high-resolution ingest channels for activity; when a recording is detected, it starts a frame-accurate proxy encode at the same time. When the high-resolution recording stops, it directs the low-resolution encode to stop as well. NEXIO AMP PRX Encoder runs as a background task showing current status of each ingest channel — no user interaction is required. All proxy files generated with NEXIO AMP PRX Encoder are universally accepted MP4 files stored on standard storage devices.
The H.264 MP4 proxy files generated by PRX Encoder are available for browse viewing with any standard media player. Alternately, due to the unique implementation of the global proxy file format, the MP4 files created by PRX Encoder can be viewed in a Harris® PRXPlayer or through the NEXIO® Mediabase™ plug-in with all of the same metadata information that is saved with the high-resolution files on the NEXIO SAN.
These MP4 proxy files are also available for editing with version 2.0 Velocity PRX™ proxy editors. Projects edited with Velocity PRX using global proxy files can be conformed directly to high-resolution clips using the NEXIO® InstantOnline III™ conforming engine or sent to Velocity ESX™ and/or Apple® Final Cut Pro® for high-resolution finishing.
