2.4.3. Partially Restoring Clips
Introduction
Partially restoring clips is only possible:
• in IPDirector, not in the Deep Archive Manager
• if IP2Archive interfaces with Front Porch Digital 's DIVArchive and SGL's FlashNet
• if the low-resolution video file of the source clip is available.
Workflow
The partial restore workflow proceeds as follows:
1. In the IPDirector Database Explorer the user searches for the low-resolution video file
of a clip that has been archived.
2. The user sets a new In and Out point within the boundaries of the archived clip.
3. He creates a subclip by clicking New Clip.
IPDirector will give this subclip a new VarID.
4. The user drags and drops the clip in the Request Restore bin.
5. IP2Archive Communicator which continuously polls the Request Restore bin detects
the clip and enters the restore requests in the IP2Archive database. It moves the clip
to the Restore in Progress bin. In the Deep Archive Manager the clip appears in the
Restore Queue tab.
The VarID of the archived high-resolution file is retrieved from IPDirector using the full
file path of the low-resolution video file the subclip was created from. It is compared
with the VarID of the subclip.
◦ If the VarID of this subclip already exists in DIVA or SGL, this request is handled
as a “Full Restore”.
◦ If the VarID does not exist, the request is handled as a “Partial Restore”.
The TC In and TC Out of the subclip are compared with the timecodes of the archived
high-resolution file.
◦ If the timecodes match, this request is handled as a “Full Restore”.
◦ If the timecodes fall within the timecode boundaries of the archived file, the
request is handled as a “Partial Restore”. A new clip will be restored using the
VarID of the subclip as the name for the restored high-resolution file: VARID.xxx,
together with the metadata file : VarID.evs.xml.
6. Once the subclip has been successfully restored to the nearline storage, it will be
moved to the Restored bin. In Deep Archive Manager the clip appears in the Restored
tab.
IPDirector will pick up the restored file in its database and link it to the low-resolution
subclip previously made.
