System Overview
Aurora Browse is a media management and editing system. Aurora Browse supports
the complete newsroom workflow — from ingest to editing to distribution to archive.
This chapter includes the following topics:

Functional description
Aurora Browse allows desktop browsing of low-resolution proxy copies of both SD
and HD high-resolution video material. Aurora Browse provides a rich metadata
search engine that allows you to search for clips using various criteria. You can also
use the Aurora Browse application to edit stories using the low-resolution proxy,
which is accessible from the journalist’s desktop. Aurora Browse creates various
low-resolution proxy formats for high-resolution material. Proxy formats include
MPEG-1, video thumbnails, and storyboards. From the Aurora Browse application
you can also archive and restore high-resolution material. Archived assets are still
visible from the Aurora Browse application.
The system is compatible with the K2 storage architecture. Ingest is controlled by an
ingest application, such as Aurora Ingest, and incorporates the K2 system as the video
server. The SmartBin encoder transfers an incoming feed into two formats: a proxy
low-resolution (MPEG-1) format stored on the proxy NAS, and a high-resolution
format stored the K2 storage system. Aurora Browse also monitors the K2 storage to
create proxy for new high-resolution material. In this way Aurora Edit master clips,
subclips and sequences are represented in the system for editing and manipulation.
The EDL export feature creates a sequence directly in the Aurora Edit target bin.
