Okay here we go, I'm just going through the video as I watch it...
She started to kick her hip a little in the beginning but it looks like you caught it on the backside of that first barrel at the trot which is good. You still came in a little too straight to the second, but circling it multiple times with that bend was good.
One thing I'm noticing big time is your hands are getting worse. Keep them low, spread apart, and don't drag your outside rein across her neck. That's going to make her drop her should and also cause for her blowing her hip out. Pull your outside rein just to your pommel and hold it there. Keep your inside hand low and to your pockets, and use your legs to hold her off the barrel. Right now it looks like your inside rein is being used to try and hold her off, which is making her bracey and is going to cause problems when you go faster. If she is trying to cut in on you, use your inside leg and counter arc her away from the barrel and leave it, or walk past the barrel to keep her stood up. Don't bring your hands up unless you wanna move them somewhere.
However, I do think that bend helped with her hip kicking. She did take a step out with her hip at the end of the second but it was in while you were circling which is improvement.
You can really see it on the third barrel first time through, you're not giving her the angle. Start bending her WAYYY out there, thirty feet out, halfway between the first and the second "tap tap" inside leg and bend her. Don't forget soften, bend is nothing without softening, but at this stage any little improvement is good.
On thing I'm noticing too is you are constantly on her face. Loosen your reins when she gives to you, relax a little, breathe her down if she gets hot on you. She's swishing her tail, chewing on the bit, and fighting you every step of the way because you're stressing her out. Don't pull so much, I think that would really settle her down. Just barely tighten your hand when you ask her to do something, and follow through with a gentle and then firmer and firmer pull if you need to. If you're always on her mouth, she'll never learn to soften up and come time to run barrels you'll have a lot of horse on your hands who doesn't know how to back off the bit...Which will be a lot of trouble.
The third time you went through, when you did your 360 around the first, she kicked her hip. She's kicking her hip almost every time at least one step..Which, granted, it's better than every single step that she used to do. You've gone from blowing her hip 95% of the time to only doing it about 75% of the time...But still, that's a good start, and I'm sure you'll get it down. Just think balanced thoughts. Imagine you're riding a third level dressage horse. Everything has to be right in place or they'll get in bad habits.
You really need to get this horse softening girl...The longer you wait and don't fuss over it, the worse she's going to get, and the harder it'll be to fix. Trust me, you NEED to have that button on her where she'll drop her head at the slight twitch of your finger. You'll never get her rounded up and driving from behind if you don't get her respecting the bit. Right now she's just kind of flipping you off, and since you use your hands a lot around the barrels that's not gonna help at all.
I would get off the pattern for awhile and ride like you're riding a reiner or a dressage horse. Just spend a couple weeks getting her broke, broke, broke. I know she's a hot horse, hard to handle, and very opinionated but you gotta get her going better soon or she's gonna get in bad habits you might not be able to fix.
I hope you don't think I'm being mean, that's just what I think...I don't wanna see you get in too big of trouble later on for not making the adjustments you need now.
Pssh.I didn't pick up the wrong lead
It's called a counter canter...
...A very advanced maneuver.
