3. Clips, Clip Elements
and Nearline Files
3.1 TERMINOLOGY
From IPDirector version 5.6, the following terms have been introduced:
Term Definition
Nearline Any IT storage, other than the EVS video servers, present
on the network and where A/V material can be backed up
or from which A/V material can be retrieved. These IT
Storage devices are inventoried into the IPDirector
database.
Examples of nearline storage: IP drive, XFile drive, SAN,
NAS…
On-line nearline A nearline is displayed as on-line in the database tree
when the next two conditions are met:
• It is accessible (IP address can be ‘pinged’)
• It is managed by a SynchroDB
On-line nearline file A file stored on an on-line nearline storage and which has
been treated by the SynchroDB.
It can be a hi-res file or a lo-res file.
Off-line nearline file A file stored on an IP drive nearline storage which is no
more on-line, either because it is no longer accessible or
because it is no more managed by a SynchroDB.
It can be a hi-res file or a lo-res file.
3.2 WHAT COMPRISES A CLIP?
Clips are logical entities that contain A/V media.
A clip element is the physical resource inside the clip: XT clip or nearline file.
Every element in a clip shares the same T/C IN, T/C OUT and metadata set.
