Adjust edges, blurs and brightness using Convolution presets
You can control the fine details of blurring, embossing, sharpening, and other effects by applying the Convolution
Kernel effect or one of the convolution presets based on it. Convolution Kernel, and the presets based on it, apply a
grid of brightness values to each pixel in a frame and all its neighbors, one pixel at a time. You can set the values for
each cell in the grid using sliders in the Effect Controls panel, and you can use keyframes to change these values over
time. To achieve a desired effect, it is often easier to apply one of the convolution presets and to modify it, than to
apply and modify the Convolution Kernel effect itself.
In the Effects panel, click the triangle to expand the Video Effects bin, and then click the triangle to expand the
