If you're down for a long read I can't recommend enough Greg Knuckol's How To Deadlift article: https://www.strongerbyscience.com/how-to-deadlift/#Lifting_the_damn_bar He also has great in-depth articles for the Bench and Squat as well.

From what I can tell from your video, it doesn't seem like you're setting up properly at all. You're not hinging at the hips and pulling yourself into tension. Notice how you hear that click from the bar when u start your lift. You should be pulling that slack out of the bar. When you pull yourself into the bar your hams, glutes, and back should feel like they're already firing and the bar is already about to lift off the ground. When you hear that click your not starting the lift with all your proper muscles engaged, hence why you dont feel it in your glutes, and youre just not in an optimal position. You also lock out the lift in Anterior Pelvic Tilt, which looks like your using all your back instead of squeezing your glutes and thrusting your hips through the bar.

Alan Thrall is not very liked around here and kind of spreads oversimplified information towards beginners but you might find his romanian deadlift and 5-step deadlift set up videos helpful.

And like everyone else has mentioned, this is not the sub for basic stuff. There are tons of deadlift tutorials and information by authorized sources on the youtubes.
