Welcome to PVP!
It seems like your running behind yourself - get your feet more directly underneath the center of gravity, which is shifted forward because of the pole's weight. Otherwise you can get out of control, which will lead to a late plant (and it did in this case). The late plant leads to being under at take-off, killing swing speed and making it difficult to keep the trail leg straight.
I'd also recommend adopting a slightly narrower grip. Seems a bit wide.
In the future, if you're recording on a phone, turn it sideways - the eyes are sideways in the head, it makes it easier to watch! Also, vids like this go in the "Video Review" forum.
Good luck!
