Hi gchen,
Following up on this thread — I’m running into the same issue, but with GoPro Hero 12 Black cameras instead of Hero 11s.
My setup:
- 2x GoPro Hero 12 Black, dual mount on a light stand at the sideline
- Recording settings: 4K, 30fps, Wide lens, HyperSmooth off
- Both cameras confirmed to have identical settings
I’ve tried stitching with every camera profile currently available in ActionStitch (including Hero 11 Black 5.3K full and standard), and all of them produce severe warping/vortex-style distortion on one side of the stitched output — not just minor misalignment, but the kind of extreme stretching that suggests the dewarp math is working from the wrong lens/sensor calibration entirely.
Since there’s no native Hero 12 profile yet, I’d like to request a custom calibration for:
- Camera: GoPro Hero 12 Black
- Resolution: 4K (3840x2160)
- FPS: 30
- Lens: Wide
- Stabilization: Off (HyperSmooth disabled)
I’m ready to record the calibration checkerboard footage at these exact settings whenever you confirm this is workable. Happy to upload it to Google Drive/Dropbox as soon as I have the pattern set up correctly.
Also want to flag — since I’m not the only one asking about Hero 12 in this thread, seems like there may be enough demand from Hero 12 owners to make this profile broadly useful, not just for my case.
Thanks for the work you’ve put into this tool — it’s been the most reliable stitching option I’ve found for sports footage once the calibration is right.
