Help with Deadlift Form

I have never been able to do deadlifts properly. I have very tight hamstrings that don't respond to stretching. My back is also not straight to begin with. I know people recommend Romanian deadlifts, but when I try them I can't keep my back straight and it just doesn't feel right. I found the trap bar at the gym today and made a video. Be thankful for any feedback. Thanks.

If it's a lost cause, I'll just continue not deadlifting.
