To create an Open Clip:
Use the Batch Write File node with Create Clip enabled.
Export a sequence and enable Show Advanced OptionsClip OptionsCreate Clip Data.
Use a third party application or utility.
Create one from scratch (page 1407).
NOTE When creating an Open Clip with versions, make sure the frame rate remains the same between versions:
having differing frame rates within one Open Clip is not supported by the format.
Why Use an Open Clip?
For open clip history and data exchange.
Open clip history Open clip history provides you with the ability to save with a processed clip the Batch
setup used to create that clip. Later on, to open that clip in Batch or the Timeline and edit previous nodes
and their settings.
Data exchange Data exchange requirements with a facility's shot management system. In such a case, the
.clip is a file created by a third party system, allowing something else to define a source using instructions
contained within the file. In this case, the clip can contain a list of render passes for you to composite in
Smoke through the Read File node.
Working with Multi-Version Clips
Multi-version workflow requires the use of Open Clip files, and is an extension of the publish workflow.
The following features are available when you use multi-version clips. Open Clip allows marrying versions
of similar content like CG renders from Autodesk Maya, and integrates well with Autodesk Shotgun-based
workflows.
A multi-version clip is a construct where a single file (using the Open Clip .xml format) contains the
information required to assemble media files into different versions. Export's Publish and Batch's Write File
node can both generate Open Clips with versions. Or you can build your own Open Clip using the developer
available developer documentation.
It is possible to have versions of different start, end or duration: versions are aligned internally based on
their timecode. The duration is then derived from the earliest versions' start time to the latest versions' end
time. Different versions can reference different media formats.
Multi-Version Clips in the MediaHub
In the MediaHub, you can identify a multi-version clip by its V badge.
The MediaHub displays the latest available version of multi-version clip. But you can use the Preview Panel
for additional information: the Versions tab displays all the versions contained in the Open Clip, as well as
the location of the Batch Setup, when one is available.
