U dont know its blood. Btw Here is a fun fact: VHS tapes generally produce a screen image characterized by a low resolution, a 4:3 aspect ratio (although some widescreen content was accommodated), and a visual style influenced by analog imperfections. These imperfections include color distortions, washed-out hues, oversaturated reds, and faded blacks, as well as static and noise, resembling "snow" on the screen.
