If that is short pimple I think you brush to much over the ball. I think that is why the ball goes in to the net. Try to have open racket angle and hit it flat almost under/on the bottom of the ball.
If your natural technique is like in the video, that you brush over the ball I think an inverted rubber would be better suited.
People that are naturally good at flat hitting/smashing should think about trying short pimples. So if you are good at brushing the ball and creating spin, inverted is the way to go.

These are not SP strokes and you are not getting SP results. Thw bat is too closed and you are swinging from below table height up to your chest. Your partner even blocked a few off the end. With SP hits you would expect him to play in the net.
You are basically using your pips like a bad inverted by trying to topspin with them. That is what everyone does who tries to switch from inverted to pips without completely changing their stroke and timing. You can do it. It just doesn't allow your pips to do their job.
