Preface: this was shot using two Go Pro 9’s at 4K/30 on a SeeUsPlay rig. I have two Go Pro 13’s and a 3D printed mount on the way to do a comparison.
Any idea why players are disappearing/reappearing at the center line? I tried to manually sync the videos, but no luck. I tried to manually stitch too with 6-8 stitch points with the same results.
This is a stitching issue. If you want to use GoPro 9 you need to shoot at 5K resolution. This is because the only available calibration file for GoPro 9 (actionstitch-player/calibration/gopro_9.npz at main · gilbertchen/actionstitch-player · GitHub) was created for 5K, not 4K.
@gchen I tested out my new Go Pro 13’s using the existing calibration file that your team previously created. Do you think I am having a calibration issue? I tested two mounts: 3D print from your STL, and the SeeUsPlay rig.

SeeUsPlay Rig The field looks great but the clouds are blurry
Received some footage from the $1500 and $1200 a year Pixellot Air and it has ghosting as well. Just as a point of reference. I think the footage needs some space around the field to create the best stitch. That has been my experience.
@kteeeee stitching looks good to me in these images, but the best way to determine if its is correct is to check the stitching dialog (https://actionstitch.com/img/screenshot_stitch.png). The overlapping area should appear clean and sharp. If it is blurry and even has a double image, that means the stitching is off.
