Video shot with the skier coming at the camera is much more helpful than video with the skier going away. Video shot with the videographer stationed in place allows a more stable clip to be shot. In the future, these changes will allow better MA to be performed. What you've got is very hard to MA.
From what I can tell, it's a fun run, you've got some nice angulation and you're not getting knocked around by the snow. Your weight is in the back seat a lot and as a consequence your turns start with an up move and the skis pivot a lot through the turns. It may be that you are more back than normal due to the fresh snow, you may have an alignment issue, or it may just be that you just need to stand taller from the waist up and consciously keep your hips forward to keep your upper body moving with the skis more than getting dragged by them. I suspect it's the last reason. Thus, my recommendation is that the best place to have more fun skiing is to work on your stance.
The easiest solution is to take a lesson and have the instructor see if a change in technique can get you into a centered stance. Sometimes we recommend going directly to a boot fitter to get checked, but my guess is that a technique change alone can make a big change. Since you're posting here, I'm assuming that you are seeking a less expensive solution. You can try on your own to see if you have fore/aft alignment issues that are pushing you into the back seat, but this is very hard to do by yourself. It's much easier to have a trained eye making the analysis, but you can either try by yourself or have a friend help. One exercise is to ride straight downhill on a "flat" run and determine which point on your feet feels the most pressure (from the toes, to the ball, to the arch, to the heel). Consciously try to move the pressure point forward and back to hit all four points. Check what body movements you have to make to do this. If you have to bend at the waist to get the pressure onto the balls of your feet, you may be a redneck
- oops - make that you may want to see a boot fitter. Ideally, you want to be able to line up your toes, your knees and your nose and feel the pressure under the center of your foot (between the balls and the arch). If you can't find a problem there, get a friend to help you. On a very slow down hill pitch and have your friend sit down on the snow. Ski very very slowly straight by your friend so that he or she can reach out with one hand and push both of your boots or bindings from behind for about 1-2 feet as you slide by (gently - just enough to add one MPH). The first time, the objective is to let the skis get pushed ahead so that you can feel getting pushed into the back seat. The second time, you should anticipate the push and counter act it by moving your hips forward to prevent getting pushed into the back seat. You should be able to feel the skis pushing your upper body forward. If you can't stay with the skis after repeated tries, then you may need boot adjustments. We want to have this kind of hip movement when we are about to turn because as the skis turn toward the fall line, they start to go faster. If we don't move our hips, it's the same thing as the first time our friend pushed us. The idea is that when we're turning, we need to move our hips not only forward but also laterally in the direction of the new turn so that our weight is ahead of where the skis are pushing us. You've already got the lateral component down. That's what causes the angulation. Other exercises that can help develop this movement pattern are the PMTS phantom turn, thousand steps (making small steps constantly throughout a turn) and starting turns with a skating move (stepping the inside ski into the new turn).
