# Motion Blur Augmentation

Apply directional blur that mimics the streaking caused by camera shake or fast-moving subjects, helping your model stay accurate on motion-affected footage.

Motion Blur Augmentation is an optional augmentation step during the [Image Augmentation](/datasets/versions/dataset-versions/image-augmentation.md) (when creating a [new version](/datasets/versions/dataset-versions.md)). Below are the settings that can be configured for motion blur:

* Length: The length of the blur in pixels. Higher values produce a stronger, more pronounced streak.
* Angle: The direction of the blur, in degrees, along which the streak is applied.
* Frames per blur length: How the streak is distributed across the blur length. Higher values create a smoother motion trail.
