I had posted this in a response form something form some time ago but it did not seem to post. I am attempting to level a dual image 360° image. See two screenshots. One is the control point section with #25 & #23 as horizontal control points and #24 as a vertical. The leveling results are atrocious. Please help.

Hi Bill,
To level a panorama, you generally select the same image in both panes
in the control points tab.
Then find a vertical feature, and add a vertical line control point pair
there. The two points of the control point pair should be at different
positions on the vertical line.
See the video tutorials, part #8:

So in your example it doesn't work because you've selected two different
images in the CP tab, and placed a control point in the red masked area
which is not correct.
Kind regards,

Bill, You can also level an already stitched 360x180 equirectangular image by simply loading the image into PTGui and setting a few vertical line control points, followed by running "Level panorama" from the Edit menu on the Panorama Editor window. For full 360x180 panoramas, horizontal line control points are generally only used on the natural horizon (when visible) to level and straighten it.

So this is becoming more frustrating. See screenshots.
I open the project.
It creates two images as it is from a 360° Camera DNG.
It generates Control points.
After optimization is creates way "Not leveled" work.
It fails to straighten
It fails to level as I did not yet add horizontal or vertical points.
When I attempt to add those points. I may start a horizontal control point on only one image then it auto directs the cursor to the other image and in the red zone. When I do create a vertical and a horizontal point. Its results are Way off.
OMG please help me through this. It makes no sense to me.
Yes I have used vertical and horizontal points countless times in my DSLR stitching.

Hi Bill,
Unfortunately the Insta X4 and later do not provide leveling information
in their metadata. I've contacted Insta360 in the past but got nowhere.
So you need to level the images manually.
The Straighten Panorama function only works if the panorama was taken
already leveled (using a bubble level on the tripod). This adjusts the
panorama until all images have the same pitch or roll. If your panorama
was taken hand held this will not help.
There are two ways to level a panorama manually:
You can drag the panorama in the panorama editor until it is level.
First drag with the left mouse button until a point on the (physical)
horizon matches the center point in the panorama editor. Then drag using
the right mouse button until it is level. If you can't see the horizon
(for indoors panoramas) this can be a bit tricky but it's still doable.
The other is by placing vertical line control points. It's important to
select the same image twice in the control point editor. So you have
image 1 selected at both sides. Then place a Vertical Line control point
on a vertical feature. Them place the second half of the vertical line
control point on a different point on the same vertical feature (in the
other panel).
To learn mode please watch the video tutorials:

Video #8 explains leveling using control points.
