Not like the whole video goes from 1080p to 720p or something but single bits of the drive will fails over time. If that bit is part of your video file, one pixel of one frame will be the wrong color/black. If multiple bits close to each other fail you might get a video stutter. If even more fail your video player will not play the video at all (or just stop playing at the place of the errors).
Oh yeah I was aware that it won't change from 1080 to 720 :p.
But I thought the movie would just be corrupted an unplayable not lose quality bits !
Nope, on my first homelab setup some years ago (Raspberry Pi + 4tb HDD) i managed to drop the HDD and had to do some data recovery-fu to get my files back, and a lot of movies had artifacts from then on. 90% of the movie were fine but every few minutes there were compression errors with parts of the picture turning green or grey, among other graphical glitches.
