Insta360 OneRS 1-inch owners - what are the benefits to using PTGUI?

[Victor Lin]

I don't own the camera but I've been able to play around with some original files.

The Insta360 Studio app is able to automatically take exposure bracketed DNG files and stitch and merge them into a 360 16-bit TIF, but I've noticed that it's not ideal as it still ends up clipping some highlights. 

You can import the nine exposure bracketed DNGs into PTGUI and do the merging there, as well as save as a 32-bit TIF which helps preserve highlights, BUT the stitching is a lot more cumbersome. The Insta360 DNGs have the two hemispheres stacked vertically on top of each other and PTGUI is not able to automatically find enough control points to stitch the image together and to figure out straight vertical lines - you have to manually add control points and vertical lines yourself, which is very time consuming.

So, for owners of the OneRS, where (if at all) does PTGUI fit into your workflow?

Hi Victor,

You would create a template for camera, see 6.41:
https://ptgui.com/support.html#6_41

Then the images can be stitched without generating any control points.
The template must be created for your specific camera, because each
instance of the camera may have slightly different lens offsets.

As for the leveling, PTGui can automatically level many one shot 360
camera images using the accelerometer data. I'm not sure if the OneRS is
supported. If it is not, please send me some images taken at different
camera orientations and I'll see if PTGui can support this.

That said, if the camera's stitching tool produces good images, there's
probably not much benefit in using a generic stitching application such
as PTGui.

Kind regards,

Hello. I have the Insta360 One RS 1" inch camera.

Yes, the DNG circle are stack verticle. I wish the 2 fish eye is side by side.

I edit in the 2 fish eye with the brackets, using luminosity masking, I try my best looking at the fish eye. Once I am done, I save as TIFF and let PTGUi do the stitch. I dont do any tone mapping or contrast adjustment inside PTGui.

PTGui Pro stitch it perfectly 90% of the time. I dont use any templates.

I wouldn't recommend stitching dng because you'll be missing the aberration correction which yields a pretty big quality boost in my opinion.

Photoshop can correct it and then you can stitch that tif. The insta360 one app also does aberration correction. I'm not sure which is better though.
