I’ve imported 4 files, and trying to stitch them together. Either there’s a menu I haven’t found yet, or can you only stitch 2 feeds into a 360 video? musing movie edit pro premium 19.0.1.18
I can't directly answer your question since I've never tried to create a 360 video, but, assuming your Update Service is still current, your version of MEP needs updating to the current, 19.0.2.58.
It says you can use up to 6 GoPro type cameras and use movie edit pro to stitch them together. I don’t however think the software does this type of stitching. I don’t think it can stitch from multiple cameras. if anyone knows different please let me know
Actually I don't think it say's that at all. Read it carefully. It's giving examples of what is possible to do depending on equipment. Only the paragraph above the one you mention refers to using MEP on a different type of editing.
You should read the pdf manual pages 225 to 231 for a more detailed explanation of what is possible and the exceptions. I think you need may additional software for the additional stitching this would need as some functions only appear to be supported on a few cameras.
