Rectangular canvas with full elliptical / radial gradient

[Dekade]

1. For purposes of video backgrounds / editing I want to create different elliptical and radiant gradients to fill a 1920 x 1080 video size.
2. I have no problem making the gradients.
3. I do have the problem of making the elliptical and redial gradients fill out the entire rectangular canvas. How do I do that without the gradient being linear
4. Is there anything in particular that I need to do to the canvas to make it representative of a 1920 x 1080 size. Or - am I over thinking that particular aspect.

Thanks for any help, Dekade

Thanks Hens, I think this will get me where I want to go.

This will be hard to explain but I'll try.

1. I also want to be able to move around an elliptical or radial gradient as a whole and the background stays the outer most color of the gradient
2. Do I first make a layer with the gradient
3. Then do I make another layer as the background with the background layer color being the same as the outer most portion of the gradient?
4. Example: the elliptical or radial gradient could be a series of blues transitioning out to all black
   1. But - I want to be able move/reposition the [blues to black] gradient all around without exposing any white canvas.

Does the Fill Tool get you anywhere?

Your video is exactly what I want. However, I'm not sure of your question meaning on the purpose of the fill tool. Fill in the background?

I drew a single rectangle covering the entire document, then applied an elliptical fill:

 

 

I then used the Fill Tool as in the video to adjust the positioning of the gradient. No need for any additional layers or backgrounds.

Interesting. I'll use it all. Your help means a lot to me. Thanks for your time.
