Hello smartpug967,
We understand wanting to change the settings to your iPhone camera. Here are a couple of links that go over various settings and features available:

The Clips app does allow for changing the aspect ratio for videos, and you can check out this relevant information about how to change the aspect ratio:
"Set the clip aspect ratio
You can set a clip’s aspect ratio (the ratio of the image’s width to its height) before you record it. On iPhone, clips are recorded by default in a 16:9 aspect ratio (the most common widescreen aspect ratio). On iPad, clips are recorded by default in a 4:3 aspect ratio (the most common portrait aspect ratio). Videos shared on social media usually have a square aspect ratio.
- With a video open in the Clips app
, tap
in the upper right. - Tap 16:9, 4:3, or Square."

We hope this helps.
