You need a camera with better white balance or you need to get it forward to get more of the dash out of the picture (which will lose the hands and I'm sure you don't *want* to do that). My first "cone-cam" did that.
As for the "hack-master" thing, I assumed you were joking until I watched it. You do a turn-open-turn before almost every apex. Are you loosening the car up with that, or do you just have a bad habit of turning in too much? Yes, some sawing of the wheel is normal in the carousel, and you do the twitch a lot less in the faster corners, but it's pretty pronounced in some of the slower corners. Which makes me think you're doing it on purpose...but it's hard to tell much about the car attitude in the video.

The car oversteers at turn-in on 1, 3, 8, and 14. If you look at the pavement on those corners, the "grippy" patch starts about 1/2 of the way from turn-in to apex. I could slow down the turn-in and entry speed but I have a lot of grip on the patch at apex. So I pitch the car in a little too fast for the available grip, deal with the oversteer, then by the time I'm on the darker pavement at the apex, all is good.
I didn't see many cars doing that, so it's likely a combination of aging tires and/or suspension setup.
On the grippier corners without the patch it's not an issue. I never, ever got a hint of oversteer in 12-13. Mild understeer in fact. So it's definitely a pavement/grip issue.
In the carousel it's just the bumps that make the car rotate. The pavement is nice and grippy all the way until about 20 feet from trackout, where it changes back to old slippery stuff. Same thing in 8 -- if I'm not judiciously straightening the wheel in those 2 turns at 3/4 of the way through, I'm going to end up in a spin.
