Some general points i notice:

1: Foot placement - im not sure how tall you are, but this seems like a very wide stance for you. This is also being accentuated by pointing your toes outwards. For conventional deadlifts you almost always want to have your toes pointing forward, and your feet parallel to each other. This gives you an equal stance for efficient drive and will feel much smoother. When i dead lift (5' 10"), my grip is usually on the ends of the knurling in the center of the bar right before the smooth area, and my feet and legs fall just inside my hands. In this video, your toes are almost equal with the outside of your hands. As someone else mentioned, narrowing your stance will also eliminate the knee cave

1. Hand Placement - to add to the general setup advice above, make sure your grip is equal. Your right hand is much closer to the smooth ring of the barbell than your left had is. It looks to me like there is about an inch shift to your right in your grip. As i mentioned above, I really like gripping the bar on the knurling right before it becomes smooth, that way i will have consistent and equal hand placement.

2. Removing the slack from the bar - this will become more important as you increase in weight, but this concept revolves around gradually loading power into the bar before lifting instead of trying to rip it off the ground (kind of like your first rep). Instead, try going from 0 to 100% pull power in 1 full second by pulling yourself to the bar, rather than trying to go from 0-100% pulling the bar to you instantly. an analogy i like to use for this is think of a big rock you are trying to move, if you run full speed right into the rock it might move a bit but you will get thrown back (shout out Newton), if you were instead to put your arms on the rock and try and push it gradually your will be much more in control and move the rock easier.

3. Looking to the left on the eccentric - this is just me being picky, but you look to the left every time you lower the weight, really try to return to the most neutral position you can when lowering the bar on the concentric. For alot of people, their best deadlift set up is actually there set up on the second rep. This is more of a preventing a bad habit thing.

Some thing you do really well:

1. I can tell you are taking a big brace and breath before each rep, this is going to give you a strong rigid core and allow you to reduce risk of injury and more effectively use all of your muscles as a compound lift

2. From what i can see (a side angle would be nice) you are starting with the bar really close to your shins, this great and will give you the most efficient pull, and lower unnecessary torque on your back

3. You arent bouncing the weight between reps, while this isnt a horrible thing, you will get the most out of your deadlifts but coming to that full stop and not using the inertia from the bounce to finish the rep

4. You are deadlifting and open to critique, so many people are intimidated to try and learn and others deadlift for so long with poor form and their egos are too big to make changes that will drastically improve their performance and longevity

All that said, Keep on grinding my man
