Open Clip Reference
The Open Clip is an XML structured file with the following information.
- Physical location of files
- Metadata information, such as timecode
- Structural information, such as tracks
- Clip versions
You can view the Open Clip as something similar to a P2 clip: the Open Clip is a wrapper for media files (or essence), and it structures these media files.
General Notes
The <version> property is only mandatory for top level elements. If <version> is missing from a child element, it is inferred from its parent.
Important: This document lists every possible xml-element for completeness sake. Some of these elements might not be described within. This is normal and indicates elements that are private and should not be relied on for third-party development.
An Open Clip cannot contain mixed frame rates, either within a version or between versions: every feed in an Open Clip must use the same frame rate.
Open Clip and .clip (the Open Clip file extension) are used interchangeably in this document.
This documents to use notation as close as possible to DTD definitions:
- xml-element?: zero or one instance of xml-element
- xml-element+: at least one instance of xml-element
- xml-element*: any number of instances of xml-element
- #cdata: a placeholder for data described in the xml-element description, usually a string of any valid characters
