Inputs

(Note: “*” as a property value means that the property is required but can be any value.)

• http://clams.ai/vocabulary/type/VideoDocument/v2 (required) (of any properties)

Configurable Parameters

(Note: Multivalued means the parameter can have one or more values.)

• mode: optional, defaults to content

  • Type: string
  • Multivalued: False
  • Choices: content, threshold, adaptive

  pick a scene detector algorithm, see http://scenedetect.com/projects/Manual/en/latest/cli/detectors.html

• threshold: optional, defaults to 27

  • Type: number
  • Multivalued: False

  threshold value to use in the detection algorithm. Note that the meaning of this numerical value differs for different detector algorithms.

• pretty: optional, defaults to false

  • Type: boolean
  • Multivalued: False
  • Choices: false, true

  The JSON body of the HTTP response will be re-formatted with 2-space indentation

• runningTime: optional, defaults to true

  • Type: boolean
  • Multivalued: False
  • Choices: false, true

  The running time of the app will be recorded in the view metadata

• hwFetch: optional, defaults to false

  • Type: boolean
  • Multivalued: False
  • Choices: false, true

  The hardware information (architecture, GPU and vRAM) will be recorded in the view metadata

• tfSamplingMode: optional, defaults to representatives

  • Type: string
  • Multivalued: False
  • Choices: representatives, single, all

  Sampling mode for TimeFrame annotations. Has no effect when the app does not process TimeFrames. “representatives” uses all representative timepoints if present, otherwise skips the TimeFrame. “single” uses the middle representative if present, otherwise extracts an image from the midpoint of the start/end interval (midpoint is calculated by floor division of the sum of start and end). “all” uses all target timepoints if present, otherwise extracts all images from the time interval.

Outputs

(Note: “*” as a property value means that the property is required but can be any value.)

(Note: Not all output annotations are always generated.)
