How I align images and optimise them in Metashape ready for export to Postshot using the COLMAP format, including alpha masks.
I also discuss the merits of using the Pinhole camera transform, as well as a sneaky cheat to get a better pointcloud and cleaner gaussian splat result.
The python "combiner gui" script can be downloaded here https://discord.com/channels/1177235109162799105/1328414890175500299/1332324810981773393
[I recently uploaded the script to Github here https://github.com/PLAN8VR/alpha-mask-combiner-gui ]

I ask a couple of questions in the video, if you know the answer, please leave a message below. Also any tips on Metashape optimisation workflows. appreciated.
Hope the workflow is of help.
