Configure Keyframe Extraction

To extract keyframes from video

  1. Create a new configuration or open an existing configuration to send to Media Server with the process action. Alternatively, you can modify the Media Server configuration file (mediaserver.cfg).

  2. In the [Analysis] section, add a new analysis task by setting the AnalysisEngineN parameter. You can give the task any name, for example:

    [Analysis]
    AnalysisEngine0=Keyframes
  3. Create a new configuration section to contain the task settings, and set the following parameters:

    Type The analysis engine to use. Set this parameter to keyframe.
    Input (Optional) The name of the image track to process.
    ForceAfter (Optional) The maximum time interval between keyframes.
    QuietPeriod (Optional) The minimum time interval between keyframes.
    Sensitivity (Optional) The sensitivity of the engine to scene changes.

    For example:

    [Keyframes]
    Type=keyframe
    Sensitivity=0.6
    ForceAfter=5minutes
    

    For more information about the parameters that you can use to configure this task, refer to the Media Server Reference.

  4. Save and close the configuration file. If you modified the Media Server configuration file, you must restart Media Server for your changes to take effect.
