OK, not to take a complete dump on you here, but

A) You are using the clutch completely wrong. The clutch should only be used when starting off from a stop, shifting, or coming to a stop to keep the engine from stalling, any other time it should be all the way out with your fingers off of it (unless preparing for a shift or start/stop). The way you keep clutching in whenever you slow down a little bit (nowhere near the stall rev point) is not how you should be controlling speed and it seems like you're constantly dragging the clutch which is SUPER bad for it and will burn it up quickly. It's also just not a good way to dynamically control the bike. If you're concerned about the bike jerking, that needs to be controlled with careful throttle input, not by dragging the clutch. /r/Justrolledintotheshop has mountains of posts of people burning through clutches by doing this with cars, and though a motorcycle clutch is more durable, it's still very bad.

B) Some of those corners you were taking at speeds way beyond your skill level, and that's not a compliment. You need to brake more before a tight corner and accelerate through it, not coast with the clutch pulled in, that bottoms out the suspension and increases the chance of scraping pegs and going down. You also seem to be counter-weighting the bike which actually leans it more, which is the opposite of the way you should be leaning. I know a lot of people get that wrong as they think leaning more=cool, but you actually want a body position for less lean so you have more room for net cornering force.

Please don't take this as "mansplaining" or anything like that, but please trust me you have some dangerously bad habits you need to recognize and correct. Many guys are guilty of these things too.
