Alternative Workflow-driven media imports
Alternative Workflow-driven media imports
The Workflow service can be used as alternative method of media registration in iTX. The
Media Import Workfow speeds up file registration and can use a special media analysis tool
after initial registration to extract more metadata and information about the file. This is
referred to as Deep Analysis.
The same tool, known within iTX as FPP can also be used to register certain types of media
instead of the usual method deployed by the Media Watcher.
FPP is currently the only method by which iTX can import LXF and AVC-Intra MXFs. This is set by
default in iTX upon installation, but a special configuration tool can be used to assign the
registration of other media type to FPP. For further information, please see the section Media
Import Configuration Tool below
When a file is imported, the Media Watcher must read through then analyse the whole file in
order to extract accurate information about the clip’s duration etc. This can be time consuming,
especially on long play or large hi-res media files.
Importing using the Workflow Services allows quicker registration because analysis of the new
media is broken down into two phases. A quick analysis takes place first allowing the clip and its
basic details to be registered in the iTX Database rapidly. This is done by placing the media in a
configured ‘watch folder’ much the same as Media Watcher’s Inbox and the Media Import
Worflow reacts to new files placed in this folder.
A separate Workflow is then triggered following initial registration to allow the Deep Analysis of
the media. Media Import Workflow can move to the next file that requires registration. The
database is then updated with the further information on the new Media Asset when the
second phase of registration is complete.
The types of information extracted can be configured in the workflow itself and could be such
things as Field order, the AFD information stored in the VANC and whether the clip has Dolby
digital audio etc.
Note: The Workflow Service along with the associated workflows require a licence to register
media in this way.
Please see the section on Workflow (page 377) and also the Grass Valley iTX Workflow User
Guide for further details.
