I understand that this is not a 4K camera but I am interest to see the final quality of the stitched video. Do you need to add support in the dropdown first to adjust for the lens?
Can you take a video of a checkerboard like this: https://download.actionstitch.com/calibration_sample.mp4
Usually I would suggest printing the A2 25mm one from Calibration Checkerboard Collection | Mark Hedley Jones, but since this is a 2k camera, a smaller one like http://boofcv.org/notwiki/calibration/letter_chessboard.pdf should work.
Let me know if this works. I only have A4 paper at the moment.
Here is the calibration file: actionstitch-player/gitup_g3_duo.npz at main · gilbertchen/actionstitch-player · GitHub
