Change Composition Frame Format

I create a 1080x1350 composition.
This composition is made with Image Plane, Renderer3D and one 3DCamera.

I will now like to change the view to another format 1920x1080.
Under File -> Preference ->MyComposition -> Frame Format -> i changed the format to 1920x1080.
Save and close the Composition. Then reopen but the view still the old one.
I then delete the Camera and add a new one but nothing changed.
I then changed in the Background Node --> the Image Wight and Hight to 1920x1080 but i still
have the old 1080x1350 frame format.

What I'm doing wrong ?

Solved.

My workaround is the following.
1) In Fusion i select and copy all the nodes.
2) Then i open a text editor
3) in the text editor i paste the node, you will see lines of code
4) i then search for 1350 and manually change those Values
Width = Input { Value = xxxx, },
Height = Input { Value = yyyy, },

If there is a bette way, please let me know.

thanks

When you enter the 3d world, the render 3d drives your final output size.
if your render 3d is set to the original size, that is what it will output.
