# Keyframe Analysis

Keyframe analysis identifies key frames in video. A key frame is a frame in which the scene changes significantly from the previous frame.

Configuration Parameter | Description
--- | ---
ForceAfter | The maximum time interval between keyframes.
Input | The image track to process.
QuietPeriod | The minimum time interval between keyframes.
SampleInterval | The interval at which frames are selected to be analyzed.
Sensitivity | The sensitivity level for detecting scene changes.
Type | The analysis engine to use. Set this parameter to `Keyframe`.

## Output Tracks

The following table describes the tracks that are generated by this engine. The Output column indicates whether the information contained in the track is included by default in the output created by an output task (when you don't set the `Input` parameter for the output task).

Output track | Description | Output
--- | --- | ---
`Result` | The input image track filtered to contain only UUIDs for records corresponding to key frames. | Yes
`ResultWithSource` | Contains the same information as the `Result` track, but also includes an image for each key frame. | No

To see an example record, use the action GetExampleRecord.
