Can't do true zoom w/Transform1 node in Fusion

In the edit tab you can an easily take even a small part of an image (like my little head) and enlarge it to fill the entire screen by going into the Inspector and simply zooming in (see before and after below).
Before edit zoom:

After edit zoom:

Now (above) my pea-sized little head fills the entire screen. I always wanted to have a big head so I tried to do the same thing in Fusion.
(I am probably just using the right tool in Edit and the wrong tool in Fusion).

I tried (see before and after below) to enlarge the head to fill the screen with the size control in the inspector for the transform1 node...

I'm sure I'm just using the right tool the wrong way or the wrong tool but there must be a good way to do a true zoom (that actually increases the amount of viewable area in the whole frame for the item being zoomed) in Fusion.
Thanks!

The dark gray background on the left and right sides of the image in your Fusion viewers is dead area that's outside the frame of your clip - which means the clip must be in portrait mode. The image won't extend beyond the frame of the clip, it's like trying to use the zoom control of your television set and expecting to see the edges of the zoomed-in image beyond the edge of the TV screen.

I suspect the problem is that the timeline you placed the clip on is in portrait mode instead of landscape mode (for example, 1080 x 1920 instead of 1920 x 1080 for an HD project). Go back to the media page, create a new timeline in 1920 x 1080 mode, drop your clip onto it, and then go into Fusion to do the zoom.

Or perhaps you created the timeline in the correct orientation but you dragged the portrait-mode clip directly from the media pool into Fusion instead of using the timeline that it had been placed onto. If so, put the clip on the timeline, put the playhead on the clip in the timeline, and then go to the Fusion page and use the "MediaIn1" node that represents the original footage from the timeline.

Thanks for that helpful information but my question is how can I (with the same clip which was taken in portrait mode and dragged to the Edit timeline and that, in the Edit screen, can be easily expanded well beyond the scope of the original portrait area to even fill the entire landscape area as I illustrated in the images) do the same thing in Fusion (ostensibly with a Transform node or other tool).
Thanks again,
John

The way to - probably - do this is by adding a background tool in the size of your project and then merge your vertical footage on top of that. This way it will expand beyond its original boundaries in a sense.

I get the behaviour you describe when I position the timeline playhead over the clip I want and then open the Fusion page. The entire comp in Fusion then has the dimensions of the clip and I don't know how to change that. (Adding background node doesn't help).

Instead you can right click on the clip in the timeline in the edit page and chose "New Fusion Clip". This way the composition in Fusion will have the same dimensions as the timeline.

Alternatively create an empty "Fusion composition" from the Effects panel, open it in Fusion. Create a background. And then drag the clip from the media pool and connect it to the background via merge node (background = yellow connector, clip = green connector).

Thanks Martin!
This (one of your suggestions) was the solution:
