How do I blend duplicated masked layer, with original layer underneath, seamlessly?

Background of grass, mountains with clouds moving -

I duplicated the original layer, masked the clouds, repositioned the mask to cover the grass and the mountains.

The purpose is that the entire screen will be filled with clouds.

Now I want to create a seamless transition between the original clouds and the masked clouds, like in photoshop where you have a black and white brush with low opacity so you can blur out the harsh lines.

Can anybody please help me?

Ok this is what I've done so far, thank you!

What do I do if I want the clouds to now scatter while revealing a different footage?

Here's a quick example of how to achieve this. You just need to tweek it according to your footage, but you get the gist.

For harsh lines, you can use the mask feather.

Ok and now I've tried to duplicate this mask because I wanted to cover the bottom third of the screen but from some reason it did not work. I even tried to create a new mask and put it there...did not work.

Please see the video attached.

Any advice?

It seems like your mask's feather is bleeding inside the frame, you need to make the mask bigger than the frame so that when the overlayed clouds fill the screen the feathering remains outside the edges.

You can either make the mask bigger, or just adjust its "expansion".

Add a keyframe for the expansion at the start of the transition and then add another keyframe at the end, and expand the mask until it fills the whole screen.
