Using the spherical camera I can sucessfully produce an MP4 video, which I then inject with some instructional magic for the player using a small python 'app' off the net. The video can then be played as a 360 video using the latest VLC player or by uploading directly to YouTube. OK, so up till now a complete success!
However, the video isn't really of a high enough resolution so I try increasing the resolution in the render settings and am then greeted by the message something like "Can't make the file" So is there an upper limit in some process that I am missing? The renderer does make up the first frame, I can watch that part, it's when it tries to save it. It's not my storage space - there is plenty left. I've tried slowly increasing the resolution (in steps of 16) and the upper limit isn't any familar number)
Any idea of the limiting factor?
