To me it clearly is a RC bug that these black strips are present with `Fit: Inner Region` parameter during undistortion.

If you want to remove these black strips, you can do so with the below kapture utility - based on a kapture project. (with the kapture library, a bit verbose, but seem to do the job). Please follow the [full workflow](https://twitter.com/jo_chemla/status/1698985750367281499) for first converting bundle to kapture, then kapture to colmap.
