I have just posted the first beta release of Panini-Video, which features better camera calibration tools, an input monitor window, and improved usability in many details. Kindly try it and report your experience. The built-in free license expires 30 days from now.
This release includes for the first time a package for Mac. I had to rework the GPU code to an older OpenGL standard, since Qt on Mac still does not deliver OGL version 3.2. As a side benefit, P-V should now run on more Windows machines too.
I have little experience building for Mac and no 2nd machine to test that package on, so it is possible it is not properly set up -- Mac users please try it and report. One thing I know is missing is the Users Guide, which can however be downloaded separately.
