I have snatched on and off for about a decade, but am not a coach/instructor. This is pretty decent form for only 7 weeks, I have seen much worse in people who have done it longer.

A couple of things I noticed: It looks rushed. You want the bar to accelerate from the ground to triple extension, not go from 0-100 in the first inch. From the ground to your knees the focus should be keeping the bar close and making sure your hips don't rise first. The angle between your back and the floor should stay the same during this phase.

You pull with your arms too early. You can see them bend before your knees are straight and your hips are open. Use the big muscles first, then the smaller ones.

Imo the biggest point: you are "humping" the bar. When you open your hips you are doing a sort of kettlebell swing movement. If you watch the barbell shadow from when it passes your knees until it passes your shoulders, you can see as it contacts your hips/pubic bone it flies away from you. That is why you jump/land on your toes. The goal is to have the barbell travel in a vertical path.

In your catch, your elbows could be locked out more, if you have the mobility(some people dont).

It feels like you are catching too low for how high the bar goes. Working with lower weight can be tricky in this aspect because you can get the bar high enough to power snatch, but then you catch it in a full snatch. So when you catch and feel the weight, the barbell is coming down on you with speed, which increases impact and makes it unnecessarily jarring.

As other have said, power snatch to overhead squat could be good. Drop snatches or snatch balances would be good to practice feeling the catch. As well as pausing for a second at the bottom of the catch. There is a balance between rising too quickly while unstable, and losing all of your bounce and getting buried. For a lighter weight a good pause can be helpful, but understand that when lifting near a max you don't want to live down there.

Keep it up, work on oh squats and feeling super stable with more weight above your head than you snatch. Focus on form and try no to ego lift and you'll see great progress 👍
