At 0:22 you played that F and didnt press pedal simultaneously which was a little delayed coused it to sound kinda fading effect. It happend to me and I was like maybe its some error inside the piano but I found that if you press a key and let go of it when the mufflers are about to silence those strings you press the pedal at the same time mufflers touch the strings. So strings are a little more quiet but still vibrating. It is an interesting phenomenon. Your playing was great and if you did that "pedaling technique" on purpose, hats off.
