I misused the terms - yes the pano was actually equirectangular 360-180 (later it was cropped to apprx. 120 )
I was talking about the projection of this equirectangular image in the final .swf project. It is probably called plane projection in English not planar.
I'd better use two examples
In the 1st tour the output projection is spherical while in the 2nd one planar
It is exactly the same project - only output projection is different.
If you crop an equirectangular image with a spherical projection to reduce the FOV it still has spherical projection.
The projection type and FOV are quite separate things.
I would describe a pano with a HFOV of less than 360 as a partial panorama.
PT/PTP can only properly handle images with spherical and planar projections. By default PTP/PTP will assume an image has a spherical projection. If your stitched pano image has been created with APP/APG and not post-processed with it will contain a Kolor EXIF tag that provides FOV data and projection type to PT/PTP automatically. The projection type you set for an image in PT/PTP should match the projection type chosen when the image was stitched otherwise it will not be displayed correctly when the tour is viewed.
The only time you would normally set a planar projection for an image is if you are incorporating single (unstitched) images shot with a rectilinear lens in your tour.
Your second example appears to use uses a partial panorama stitched and rendered with a spherical projection with APP/APG but set as a planar projection in PT/PTP - which is just silly, in my opinion.
But you can if you wish add a video to such image and it will display when the tour is viewed but of course it will not be 'distorted' to match the distortion in the pano image if you set the projection type of the pano image to planar when it should be spherical.
See my screenshots below.
So the question is - why reclangular video is ok in the 1st link and why it is invisible in the 2nd
The 2nd question - when you got to the edge of a pano in the 1st link it is cycled (you can infinitely rotate it right or left) but the one in the 2nd link is limited - when you got to the left or right edge - it stops and you have to get back
If you have autorotation set then a pano with a HFOV of 360 will rotate endlessly, a pano with a FOV of less than 360 will 'cycle' to and fro reversing direction when it reaches an edge.
