Data Fields – Clip

The Clip data type is used for a fragment of an asset. Typically, these are contiguous excerpts, but not necessarily so. Clips must have a Performance Structural Type.

The Approximate Length field must be specified for all Clips and cannot be inherited. The Approximate Length will be the Clip’s Duration plus padding, if any. Padding adds trivial material at the beginning or end (such as studio logos, disclaimers, a title identifying the clip, etc.). If the additions are non-trivial then the record should be registered as a Composite derived type.

The Extra Object Metadata for a Clip is contained within ClipInfo:

Field NameTypeCardinalityExplanatory Notes
ParentEIDR Content ID: e.g., 10.5240/7715-953F-1CCF-3501-D6CA-H   <xs:element name=”Parent” type=”eidr:assetDOIType”/>1 RequiredThe EIDR Content ID of the parent Edit or Clip.
ComponentsModeEnumeration: Audio, Visual, AudioVisual, Other, All   <xs:element minOccurs=”0″ name=”ComponentsMode” type=”eidr:componentsModeType”/>1 RequiredThe Clip’s Mode, which need not be the same as the parent’s Mode. For example, an AudioVisual Edit could have a derived clip that does not have a sound track, making the Clip’s Mode, Visual.
StartAn amount of time (xs:duration): e.g., PT4M24S   <xs:element name=”Start” type=”eidr:startingPointType”/>0-1 OptionalThe start time in the parent of the extract, if known.   See “Start Details” below and “Time and Date Details” above.
DurationAn amount of time (xs:duration): e.g., PT38S   <xs:element name=”Duration” type=”xs:duration”/>0-1 OptionalThis is the length of the clipped segment itself within the parent, not including any padding.   See “Duration Details” below and “Time and Date Details” above.

A Clip can be defined with:

Here is sample XML for the Extra Object Metadata for a Clip (the preceding Base Object Data is not shown):

<ExtraObjectMetadata>
  <ClipInfo>
    <Parent>10.5240/315D-0B78-961A-3360-896F-I</Parent>
    <ComponentsMode>Visual</ComponentsMode>
  </ClipInfo>
</ExtraObjectMetadata>

1.1.1     Start Details

The Clip’s Start is the starting point of the Clip as measured from the start of the source Edit or Clip. It is presented using the same xs:duration data type as the time components discussed in “Time and Date Details” above.

NOTE: If a single clip contains multiple extracts from the source program, then Start is not valid.

Here is sample XML for the Extra Object Metadata for a Clip that begins 4 minutes, 24 seconds from the start of the source program:

<ExtraObjectMetadata>
  <ClipInfo>
    <Parent>10.5240/315D-0B78-961A-3360-896F-I</Parent>
    <Start>PT4M24S</Start>
    <ComponentsMode>Visual</ComponentsMode>
  </ClipInfo>
</ExtraObjectMetadata>

1.1.2     Duration Details

The Clip’s Duration is the total length of the Clip as extracted from the source program. It is presented using the same xs:duration data type as the time components discussed in “Time and Date Details” above.

NOTE: The Clip duration does not include any padding added to the extracted material (leader, bars and tone, slates, etc.), only the material extracted from the source program. (The Clip’s Approximate Length in Base Object Data records the total duration of the clip, including any padding.)

NOTE: Duration applies equally to Clips that contain a single extract and Clips that contain multiple extracts from the source program.

Here is sample XML for the Extra Object Metadata for a Clip with a total duration of 38 seconds:

<ExtraObjectMetadata>
  <ClipInfo>
    <Parent>10.5240/315D-0B78-961A-3360-896F-I</Parent>
    <Duration>PT38S</Duration>
    <ComponentsMode>Visual</ComponentsMode>
  </ClipInfo>
</ExtraObjectMetadata>

For Clips based on a single extract from the source program, Start and Duration may be combined to more precisely identify the Clip:

<ExtraObjectMetadata>
  <ClipInfo>
    <Parent>10.5240/315D-0B78-961A-3360-896F-I</Parent>
    <Start>PT4M24S</Start>
    <Duration>PT38S</Duration>
    <ComponentsMode>Visual</ComponentsMode>
  </ClipInfo>
</ExtraObjectMetadata>
