The bridge should be perpendicular to the body. A tuned instrument will keep it in place with string tension. When strings are tuned, the bridge tends to tip towards the finger board. Gently push it back towards the tailpiece. There are professional violin repair shops that will replace a bridge that is warped and place it properly between the finger board and the tailpiece. Hope this helps.
I wasn’t able to view the video, but for your violin it may not be possible to use the f-holes for alignment. By chance, are you aware of or even a fan of Dr. L. Subramanium? He’s a great fusion violinist from India. Your names are similar like mine is to Mark Wood. Good luck with the bridge!
I know L subrahmanian. Fortunately I had a chance to meet and talk to one of his student. Actually now I replaced the bridge from a shop. It was that bridge’s problem. Thank you every one. Happy to know that you are liking Indian music @ Mark Woodyatt.
