I'm a freeski coach in Oregon and I see this quite often. Here are a few tips.
I know you don't want to hear this but getting consistent upright grabbed 7's first really helps.
Getting cork 7's dialed on tramp will help as well.
When you set a cork 7 you should look over your shoulder and keep you neck and shoulders upright rather than looking straight down or at your landing directly on the take off. you'll notice in your set you take off looking straight down, this will throw your rotation out of wack and often causes a "mork"
Also in your set you are setting from neutral and you need a little bit a windup do get this around better.
You probably could have got this around as an underflip 7 or super cork 7 if you had looked past the landing at 360.
Right at 360/450 your knees should be tucked up and brought up towards your chest. This allows you to cork out more and "uncork" your rotation.
Some positives in this attempt were that you were very patient and set at the proper time right as your feet came off the lip and you actually popped and were standing tall on the set which are two good things. An adjustment would be to pop a little bit taller.
Upright 7's would correct a lot of these issue but the thing that is the most important is your eyes. Remember look OVER your shoulder on the set not Under.
keep your core tight, especially right after takeoff. don't let your body loosen up where your upper half is rotating and your lower half is flopping around. bring your knees in toward your chest once you're finished setting. your set honestly looked good to me. maybe you were a bit late on the pop/set. try to pop confident right at the lip.
