The other thing I noticed was the clip was split by two horizontal lines on the screen ( see arrows ) . When the scene would move fast , you could see the difference in the picture between the top , middle , and bottom of the screen . I have done NOTHING to my PC lately and I sat dumbfounded as to why it would all of a sudden start doing this .
According to the above context, answer the following question.
Why may the narrator have not watched the whole video ?


They did n't like the visual formatting .
