My first 360 upload to Youtube didn´t really work the way I wanted.
It showed the whole 360 MP4 instead of a spherical video.
After some research I found out, there must be some Metadata inserted before uploading.
New NLEs do it automatically. But in my case I have to insert the Metadata with an extra app, provided by Google.
Here you can see my working 360 Vlog with my GoPro MAX after inserting the Metadata.
It is best viewed with a smartphone or a VR set. This way you can move your phone around and look around in the virtual reality space.
Youtube shows a up/down left/right button when you watch it on a computer. Use it do scroll around in the video.
