Feather or blur a solid?

[Zinim78]

Hello World!
Is there any way to feather or blur a solid color? Gaussian blur and Radial blur don't work as expected (By me, or like Photoshop or other graphic software.
Thanks for any help.

a combination of the vignette effect with blur could be what you are looking for.

The blur doesn't do what expected after the vignette... so it doesn't really look like a feathered square.
Sad...

Ok... Almost solved.
Cropping a rectangle and then blurring it kinda works... it creates a blurred parallelogram, which is almost a rectangle.

create a feathered black and white jpg or black-alpha png in photoshop, the you can use that as a mask for your clip.

But it can't be transformed (scale, position, etc) can it?

if dropped on a clip it will become part of your clip and transforms with your clip.
