Irt needs to watch the camera work from 20 years ago. Also the camera work from the squash world is souch better. Hard to see anything the way they do the camera work. If you want an audience you're gonna have to work on this.
My suggestion would be is let the front wall camera record the serve all the way through, its hard to tell what the ball did when it goes to the back camera, the camera transition is not fast enough or try getting a better overhead shot on the serves then once the ball goes past the foul line transition the camera.
The rule has been that you can have part of the foot over the front line for as long as I can remember. You just have to have part of the foot inside the box. You can have part of your feet outside the back of the box when you start your serve motion, too.
