I guess my calibration is off

I am trying to process GoPro 13 5.3K 8:7 video. I uploaded calibration file from Ghosting between 2 gopro 13s - #4 by gchen
and here is my view after clicking Stitch

Do I need to create new calibration file or there is better one for GoPro 13 5.3k 8:7 video?
I downloaded version 1.0.4

I believe the calibration was done using videos shot in 5.3 16:9 mode. You’ll need to shoot in that mode, or record a calibration video (GoPro Hero 13 Support + Mount - #2 by gchen) and I’ll create the calibration file for you.

Thank you so much! I guess I would need to record calibration video with just one camera, not both (on the mount)?
