In the 0:36 second of the video, the video showed a picture of codex and captioned the origin time of codex as 4th century. But the codex actually originated in the first century, and only became popular until the 6th century. (1)
The second error appeared in the 0:52 second. The cartoon is showing two Chinese movable types, and those two Chinese characters on the movable types are supposed to be reversed. And their font shouldn’t be the simplified font.
The third error is in the 1:26 of the video. Paper was actually invented as a writing surface in China around 105 AD and the paper making method was not documented until the Han Dynasty which is around 25~220AD. (2) It has nothing to do with 179~41BC.
