You need to position your feet so that the bar starts directly over the mid-foot.
Your biggest technique issue that is visible from this video is that you are starting with the bar over the balls of your feet, rather than over the centre of your feet. You can see this in these screenshots I've taken from your video, with a vertical line superimposed over where the centre of the bar started.
Having the bar over the front of your foot is a substantially weaker pulling position than having it over the mid-foot, as it requires you to lean over further to reach the bar. With correct foot position, the bar will generally only be about an inch in front of your shins when you're standing up. This will feel very close, but you can check that it's correct by leaning to either side to verify that it's inline with the centre of your feet. Don't tilt your head forward to look as that will result in you looking on a slight backward angle, rather than straight down, which messes up your perspective.
Others have comments on keeping the bar in contact with your shins - this is correct, but you must fix the starting position first, as pushing your knees forward when the bar is also too far forward will still leave you in that weaker pulling position.
(It's possible to tell that the bar isn't in contact with your shins from the fact that your hips stay stationary when the bar first moves off the floor. If your shins were touching the bar, then you'd need to start the lift with knee extension, in order to get your knees out of the way of the moving bar, and that would cause your hips to rise with the bar. But, again, this doesn't matter yet because you need to fix your foot position first.)
I'll also recommend the excellent Alan Thrall's 5 Step Deadlift Setup video.
Finally, if you're needing to take a rest in the middle of your set, the weight is very likely too high for the number of reps that you're aiming for. If you were previously able to complete the same number of reps at a lighter weight without resting mid-set, then that suggests that either you're adding weight too fast, or you're trying to force your way through a stall in progress which would actually require a rethink of your training program, diet, or some other factor.
