A movie playing tetris at a speed faster than I imagined

I am playing at a speed that I can not see if I blink. Up to this point, I think that it is close to the limit of human industry if it is extremely popular with Tetris.

The movie is from the following.
From around 4 minutes ago, the color of the block is gone. I think that it is quite difficult if the block has no color.

After 5 minutes, the fallen block is transparent. Usually, I think that I can not do it slowly.

I play double play by myself.
