You do appear to be racing down the line a bit, although it appears to be a fairly fast wave, but you could try going more top to bottom.
I would suggest checking out the Stick Surfing drills to help you concentrate on getting your hands out in front, like your board has handlebars.
Personally I use a length of webbing that I can wrap around my wrist and tuck into my sleeve when I'm paddling which is easier than trying to hold a stick in my teeth! 😬
Commented on Hello, has anyone here already tried ...

I believe there are some videos of Clay using some sort of back mounted camera setup, but I don't know what model it is.
