On your snatches you're bringing your feet up in the air a lot after the extension. Make sure, immediately after your extension, you're quickly pulling under the bar so it's a quick shift of the feet to the receiving position. However, I don't see you doing this on the cleans. Try some tall snatches and some dip snatches and focus on shortening the transition from 2nd to 3rd pull.
You're extending that back leg on some of your jerks. On that miss, it looks like you over-reached and brought your hips backwards causing you to slightly miss the weight forward. Remember to keep your back knee soft and absorb the weight with your hips straight down.
It's hard to see from this angle but it looks like your knees may be coming in a little bit on the way up when you're squatting. Force those knees out on the way up.
