Thanks for all the comments,
- Casso I used Imovie on a Mac. It's great and so easy to work with. I just opened the raw gopro file into it and cut it up from there.
You're right that the angle of the camera makes the waves look soft, it was actually overhead,

need to play around with that, I think I had the camera to close to me.
The backlit sun in WA in the arvo is a bit of a pain as well
