I'm having the exact same issue. I shot on a pocket 4k in vertical orientation. I turned the camera and natively captured 2160x3840. I didn't shoot 3840x2160 with a frame guide to crop to vertical in post. It was captured in full resolution, in vertical format, 9:16, ultra hd.
I like to manipulate the technical settings of footage before it ever hits the timeline so I did the same thing in the media tab using clip attributes>video>Image Orientation>90 degrees left. I also set the project up using the new vertical mode option in Resolve 18. File>Project Settings>Master Settings>Timeline Resolution>Use Vertical resolution. So the timeline accurately interprets the footage as 9:16.
The reason fusion does not is because it takes on the media at the source file. It does that for a number of reason that make complete sense but this is why it is ignoring the settings put in place telling it how to interpret the data. Fusion is grabbing the media early in the pipeline before settings and all that jazz are effective. It only sees the footage as captured at 16:9. There is nothing in camera saying it was captured 9:16.
So the media is accurately interpreted by the media page, cut page, edit page, etc. but not in Fusion. When a clip is brought into Fusion and any nodes are applied, Fusion's interpretation of the media becomes active, rendering the footage in a 16:9 format. Well when it takes it back to the timeline it is zoomed almost 3.2 times because it is now cutting a 16:9 rectangle out of the the small, middle section of the 9:16 footage and the timeline is now scaling it until it fills the 9:16 aspect ratio according to the settings we gave it. So it appears really zoomed in on the Edit page because the Edit page and Fusion are fundamentally understanding the footage differently. Edit responds to the settings we gave it. Fusion does not.
I'm pretty sure this is an issue requiring the developers to fix. I've spent hours tinkering with solutions. I tried applying background nodes and resizing it with resize nodes. I've tried resizing the entire pipeline with a resize node at the end. I've tried resizing just the media itself. No luck. The issue is that the media is coming into Fusion wrong. Fusion sees the footage wrong at a source level. This can't be fixed with nodes.
Although, I am very interested in the script fix that was mentioned in this thread. Can anyone expound on this? I'm going to do some research on this and come back to this thread if I find some solutions. In the meantime, if anyone discovers a fix please let us know in detail here. Thanks.
