Hey Anton
For form check videos, normal speed is fine/preferred, rather than slow motion.
The bar isn't keeping contact with your legs on the way up. Refer to the power clean and deadlift tutorials on our youtube channel to see the bar/body relationship.
You also don't seem to be jumping. Your feet don't break contact with the ground or move laterally to the receiving position. Jump harder/higher.
Address those things and you should see some improvement.
