Source Layer: can be optionally used to apply a depth map, as shown in the example above.

The rest of the image, being black, is fully blurred. The circle at the top keeps the face in focus, while the left-to-right gradient oval causes her arm to become progressively more blurred. This is based upon a simple depth map created by hand inside HitFilm using some planes and masks: Note how the face remains in sharp focus while the rest of the image becomes progressively more blurred. Here’s an example of lens blur in action: It can be used in conjunction with a depth map to selectively blur different areas of the frame to different degrees. The lens blur is designed to more closely mimic the depth of field bokeh effects created by real lenses. Lower opacity levels will give a more subtle result.

Opacity: Controls the opacity of the duplicate blurred footage.

More iterations give a smoother result, and a larger blur.Ĭreates a soft focus appearance by duplicating the footage, blurring the copy, and then blending the duplicate back onto the original footage.

Iterations: The number of times the blur is calculated.

Dimension: The blur can be applied Horizontally, Vertically, or Both.

Higher values will result in fewer edges being held out from the blur.

Threshold: Sets the amount of edge contrast that must be present for an edge to be retained.

Radius: Sets the intensity of the blur.The radius, in pixels, defines the area that will be calculated into the blur of each pixel.

Smooths images for a softer, untextured appearance, while retaining fine edge detail. Disabling it will allow the blur to expand outside the layer edges.

Clamp To Edge: Enabling this feature prevents the blur from expanding outside the edges of the layer it is applied to.

Length: Sets the strength of the blur, defined in number of pixels.Angle: Rotating the Angle wheel controls the direction of the blur.Can be useful for an impression of fast movement.

Angle Blurīlurs the layer in a specific direction. *See Motion Blur for information on the automatic motion blur feature. *Some blurs include a Clamp to Edge property, which ensures that the effect extends to the edge of the frame. The Blurs folder contains all of the blur-related effects.
