Hi there,
Some of you who are interesting by the 360 video might have a look to VideoStitch, a software we just released in beta.
It works with a PTGui / Hugin calibration files, and it relies on the graphics card to do the processing, so the stitch is very fast.
There is a demo project on the download page, if you want to give it a try ( and if you have no 360 camera yet )
After the video has been re-encoded, it works seamlessly with krpano !
Best regards,
Nicolas Burtey
