360 "follow path" not working

Hi All

I have been preparing for recording and uploading a 100 mile ride on my Virb 360. As a test for this I recorded a 50 mile ride I did.
Battery and stitching and so on (while slow) all seemed to work fine but I am having a problem with the video stabilisation.

The best "stabilisation" seems to be none. All the other seem to make it feel worse.

For a 6 hour video I don't want this. I want the video as smooth as possible and looking in the direction I was travelling and not where I am looking. This doesn't seem to be working at all though:

Is my camera broken? DOes virb edit just not work on a video this long?

What do I do?

Thanks
