Creating Discovery tapes

LTO tapes sent to Discovery need to be LTFS formatted with an XML metadata file.
Use YoYotta LTFS or Automation to put this file into the LTFS tape index partition.
Also validate tapes to ensure they conform to the Discovery format.

Create metadata XML file

Download the Discovery XML template.
Open the downloaded metadata.xml file in a text editor.
Set RecordingFormat to True for each footage type that will be on the tape.
Also edit the OriginatingNetwork, ProgramTitle, SeasonNum, ProductionCompany, AspectRatio, VideoFormat and Language fields.
Save the file. Ensure that file name is metadata.xml


Sort content

Create a folder on a source drive that will contain the footage folders.
Drop the edited metadata.xml file into the source folder.
Then make subfolders in the source folder for each footage type. Use the exact same names from the list above. In this example RED and SRAW.
Then copy or link material into these folders. YoYotta supports symlinks, these are the same as the way apps like FCPX link to clips. If you link material then make sure Copy linked files and folders is turned on in Preferences.



Setup job

Drop the folder into the job table.
Add the tape as a destination.


Setup destination tape

Remove all the tokens from the destination path, so that no extra folders are created.
Turn on Save to destination for MD5. Turn off other destination reports.
If delivery to Discovery is a regular workflow, then save this as a Discovery preset.


Completed tape

The completed tape is exactly the same as the source folder, plus it has an MD5 checksum file.


Validate Discovery tape

Ensure that Extract Metadata is turned on in Preferences. Then load a tape and add it as a new job. Open the Source Browser or click the refresh button above the Job table. This will mount, index and validate the tape.
YoYotta will check the XML metadata format, ensure it's in the index partition and check that the correct media folders are present. A summary will be shown in the log panel.


View tape in Source Browser

Open the Source Browser to see the tape layout. Click on the metadata.xml file to see a green tick, which means that the file is stored in the LTFS index partition matching the Discovery specification.
