Understanding MultiRez and Proxy Editing
1246
Proxy editing is a workflow where you edit with a low-resolution version of media and then
conform the edits into a composition that refers to an equivalent high-resolution version of the
same content.
In a post-production workflow, you capture material at a low resolution and perform what is
referred to as offline editing, then batch capture the same clips at a higher, online resolution and
relink the sequence to the higher resolution.
In a newsroom, Avid products might be configured to capture high-resolution and low-resolution
versions of a clip at the same time. Editors work with the low-resolution version and then use
MultiRez to relink to the high-resolution version for final output.
A news workgroup might also consist of a number of finish editing stations in addition to the
journalist stations. The journalist systems can work effectively with a lower bit-rate version of
the media, which uses less network bandwidth. The finishing systems use online-quality media,
which requires a large amount of disk space and network bandwidth. The journalists or editors
can use dynamic relink to switch to the high-resolution media when it comes to adding effects or
sending the final sequence to a playback device.
MultiRez and Archiving
You can combine proxy editing and MultiRez with archiving to conserve disk resources. A
newsroom editor can delete high-resolution material that is archived, continue editing a
low-resolution version, and then restore the needed high-resolution material from the archive
later. Archiving also allows a newsroom editor to keep a viewable version of a sequence online in
case a story becomes active again — the editors can restore the high-resolution version of the
sequence from the archive.
MultiRez and the Media Indexer
MultiRez is managed by the Avid Interplay Media Indexer. The Media Indexer is a background
service that keeps track of the media files in storage locations that you identify. On Avid
Interplay clients, it works with both local storage and shared storage. For more information about
the Media Indexer, see the Avid Interplay Software Installation Guide and Avid Interplay Best
Practices.

The Media Tool and Relink dialog box work differently in an Avid Interplay environment. For
more information, see “Using the Media Tool in an Avid Interplay Environment” on page 445
