Understand how to enhance or reduce the focus of your footage by applying Blur and Sharpen effects to control how soft or crisp your clips appear.
Camera Blur effect (Windows only)
This effect simulates an image leaving the camera's focal range, blurring the clip. For example, by setting keyframes for the blur, you can simulate a subject coming into or going out of focus, or the camera accidentally bumping.
Directional Blur effect
This effect gives a clip the illusion of motion.
The blur is applied equally on either side of a pixel’s center. Therefore, a setting of 180° and a setting of 0° look the same.
Gaussian Blur effect
This effect blurs and softens the image and eliminates noise. You can specify that the blur is horizontal, vertical, or both.
Reduce Interlace Flicker
This effect is useful when working with interlaced footage. Interlace flicker is usually caused by stripes that become visible in interlaced footage. It can make an unattractive pattern on your video.
The Reduce Interlace Flicker effect reduces high vertical frequencies to make images more suitable for use in an interlaced medium (such as NTSC video).
Sharpen effect
This effect improves the contrast where color change occurs and between nearby pixels to make edges and details more straightforward, reducing the soft look caused by blur or compression. For example, you can enhance detail in soft or slightly blurry footage.
Unsharp Mask effect
The Unsharp Mask effect increases the contrast between colors that define an edge.
Radius: The distance from the edge at which pixels are adjusted for contrast. If you specify a low value, only pixels near the edge are adjusted.
Threshold: The greatest difference between adjacent pixels for which contrast isn’t adjusted. A lower value produces a greater result. A value that is too low causes an adjustment to the contrast of the entire image. A low value can also generate noise or cause unexpected results.
