# Configure Keyframe Extraction

To extract keyframes from video

1. Create a new configuration to send to Media Server with the `process` action, or open an existing configuration that you want to modify.

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

       [Session]
       Engine0=Ingest
       Engine1=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, see Keyframe Analysis.

4. Save and close the configuration file. OpenText recommends that you save your configuration files in the location specified by the `ConfigDirectory` parameter.
