I don’t have compressor, what I did in this instance to preview and test the file on an Oculus headset was just the rename file extension trick. Everything worked fine and I kept the original resolution just frustrating that the file is almost 10 gig for a short VR tour!
I ended up taking it into Premiere where I was able to deal with it properly in the end to reduce it down to 900mb. I guess this is good old Apple forcing me to buy another thing.
