I had a post typed out and saved which suggested you focus solely on your gate. Then @Chris Rossi posted and I realized I was on the right path... I also watched a bunch of your other videos so my comments aren't just focused on the 14m pass.
I am with @wish in the sense that you need to consider completely rebuilding your gate, although I'm shy to say get rid of the 1 hand only because that can be a big move and 1 hand gates can work for people. I actually went to a 2 hand gate this year after most of my ski career at 1 hand (LFF), and although it is certainly not the only reason I've improved, I went from hardly ever running 32 to almost running 35 every set and a 4.5 buoy increase in pb...
My starts are far more consistent with a 2 hand gate, but more importantly I think it allows me to be in the proper body alignment which sets me up for a strong 1 and 2 ball.
You pull out nicely, but you need to stay leaned away longer in your pullout to get higher and wider on the boat. You also have too much weight on the back of the ski in the glide and loose the line a bit (notice the bow in the line?). Stand taller! The reason your ski isn't turning 246 is because there isn't enough of it in the water and your hips are trailing too much throughout the pass.
Body position is the backbone, and it starts with the gate, especially considering you are RFF and are having trouble with 2-4. Your offside turns are really nice but you're finishing with your hips back. As Rossi said, your gate setup will allow you to carry more speed and obtain better body position and thus direction off the buoy into 2-4.
I would stay away from focusing on what to do after the edge change into 2-4 because as has already been stated, a proper gate setup and approach to 1 ball will help to sort this out automatically.
