since the setup of GoPro’s is always the same… it should be possible to make template once for the controlpoints right? Meaning, if you ‘build’ a ‘easy’ setup for the first calibration, with lot’s of easy lines and clear ‘points’, you could use that template always… or am I missing something? I ask, because stitching of for example skies and so on, is very difficult… PT Gui takes more time, but works flaweless (setup 5 GoPro HD2’s)

Besides, the problem with videostitch is, that it ‘just runs’, put the video’s in it, and run… if it fails, you have virtual no idea why and how to fix it. I found the Autopano Video (trial) not very accurate, and a hassle to ‘change’ settings.

Still, videostitch and Kolorpano software are very expensive… (and you still need a ‘stitch’ program). Generally, the closer an object, the harder it will be to get a good stitch, to a point where “good enough” is all you can achieve. If you have a large difference between your foreground objects and your background objects in the overlap areas, you need to focus your control points on either the foreground or the background objects, since a good stitch can be mutually exclusive, in special cases. Placing control points helps bringing those parts together. General ideas about control points in PTgui:
Load the image sequence of the generated panoramas into your video editing suite to edit and produce the actual 360 video. Save the batch list generated by the batch builder, and drop it into the PTgui batch builder. Use the PTgui Batch Builder use “generate new projects” with the “Multiple panoramas per folder with a fixed (6) number of images (6)” method, and pick the folder that contains all the frames of your six video streams. jpg” (assuming that all 6 video streams are in sync) Convert all your 6 videos to image sequences (jpg100), following a meaningful naming convention: “. Set the proper size under the the Create Panorama Tab, including the format (jpg100 recommended). Set the proper batch stitching behavior under the Project Settings Tab: check “Perform auto exposure correction” under the align images behavior, and check “Align Images” under the Batch Stitcher Actions, depending on your scene. Alternatively, change or fine-tune the exposure compensation under the image parameters tab manually. Optimize the exposure under the “Exposure / HDR” Tab with the Settings button. Rinse and repeat steps 4-11 until you are happy with the result. #Ptgui tutorials plus
Optimize YPR plus individual HV shift, plus VP for the problem tiles. 
Delete the worst control point pairs, and re-optimize, and check the panorama editor to see if the scene is coming together. Optimize YPR plus FoV plus individual HV shift for all six tiles (if the shift values get too large, something is wrong, better undo and try something else). Generate more control points in those problem areas. Optimize only YPR, and check the panorama editor for problem areas. Optional: add 2 or 3 vertical control points. 
Manually generate control points for all relevant image pairs (with the exception of 0/1, 2/3 and 4/5).The frame set should contain all important elements of your scene, withadded elements to create control points in “flat” areas.
Apply the template to a meaningful representative frame set of your shoot (tif or jpg) with the Freedom360 (it will not really work with other setups). Quick instruction how to use the PTgui template: We will add more info about PTgui, as well as other 360 video stitching solutions, as soon as they become public. Here is a short overview how to stitch 360 videos with PTgui Pro.
