user30097: I am totally new to DaVinci Resolve. I have included a small video on top of another footage, in the bottom right corner. How can I blur the edges of this inserted video?
I am able to blur the content of the video, what is inside, but I would like to blur the edges/border of the small video, so it blends better on top of the other one.

user30097: I found the answer:

Go to Color at the bottom.
Select the clip you want to modify (the small video on top).
Add your usual nodes as needed.
Right click and Add Alpha Output. This will create a new blue terminator.
Right click and add a new Corrector node and use the rectangle, ellipse, or whatever shape you need to define the transparent/opaque regions.
Connect the previous nodes to the recently created node. Now link the green and blue points. This will make an alpha channel, making the region you marked as transparent/opaque.
If you need to use the same ALPHA node in other clips, you can create a Shared node that can be reused in other clips. Instead of adding a Corrector node this time, use your shared node.
