Could you record it again in the same tempo, without any pedal, and post it again?Sometimes you curl your fingers way too much, especially in the start. You should be playing with naturally curved fingers, so that the large fleshy part of your finger, the finger pad, is always the part which makes contact with the key.
I am not using muscles to curl my fingers, I am playing with the natural curve of my fingers. I think that's pretty basic knowledge.
Of course you are using muscles, otherwise you wouldn't be able to move the fingers at will. Here's a few screenshots from your video to show you what I mean. The fingers marked with an arrow are way too curled.For reference, look at your right hand in the first picture. It is in a quite natural position, and your left hand should be more like that too (even when playing fast passages).
