How to border a transparent video or still image

Question

Please tell me how to border a transparent video or still image.

Answer

Using Fusion, the original video/still image is superimposed as a border by coloring the expanded video/still image with the "Erode/Dilate (ErDl)" node or the "Erode/Dilate (ErDl)" node. to create. Easy to create.

From version 18, when using the Japanese menu, the node name of "Erode/Dilate (ErDl)" is now "Erode/Dilate (ErDl)".
