Hello

I'm trying to calibrate my two Hero 8 Black edition camera optics through iPi Recorder 4 calibration tool but without success. I have tested both cameras. I also tested my phone camera and sample calibration video from wiki and both were successful. I did multiple recordings and tried setting initial FOV, no luck.
Gopro settings:
1080p, 60fps
Superview : OFF
Lens setting: Wide 16-34mm (other options are Superview 16mm, Linear 19-39mm, Narrow 27mm)
Hypersmooth : OFF (records without video stabilization or cropping)
Zoom: 1x

Calibration video: https://drive.google.com/open?id=1IPtH7 ... 9s46npMj9w
Any ideas? I have more cameras arriving for test mocap session, is there some issue with this model?

Martin

UPDATE: I did get successful calibration after I checked "Pixel Aspect Ratio" setting.
