I don't know if this is a documented issue, but...

I liked this video of some movie so i can remind myself to watch it later. When I went back to look at it, the video is completely different, but the audio is still there. Someone in the comment section of this video also experienced the same thing where the original video was completely different from the one i have in the picture.

And thank god someone in the sound had stitched with the original video, so if you wanna check it out, feel free to.

But how is this possible? How could they change the video like that? Is there anyone who got the same thing?
