How do you add a border radius in Premiere Pro?

To add a border radius, or rounded corners, in Premiere Pro, you can use the "Basic Video Effects" within the "Effects" panel. Specifically, utilize the "Basic Video Effects" controls and adjust the "Border" setting. You'll also want to set the edge type to "Cut" and the fractal influence to zero for a smooth rounded effect.

Here's a breakdown:

1. Locate the Effect: Open the "Effects" panel in Premiere Pro (usually found in the top menu under "Window" -> "Effects").

2. Apply the Effect: If you want to use a dedicated effect that has border options, search for something like "Basic Video Effects" and add it to your clip.

3. Adjust Settings:

   • Edge Type: Change the edge type to "Cut."
   • Fractal Influence: Set the fractal influence to "0". This creates a smooth, rounded edge.
   • Border: Increase the "Border" value until you achieve the desired roundness for your corners.

By manipulating these settings, you can customize the border radius to achieve your desired aesthetic.
