Why does the permanent timestamp in CCTV footage sometimes change color?

  No one gonna mention anything about how that dude is lucky to be alive? Holy shit I thought this was going to be a different kind of video.

  For contrast so the text remains readable.

  Like others have said, for contrast.

  Though, they’re not exactly “permanent.” Depending on the encoding, they’re potentially pretty easy to remove. (If it’s encoded to meta data. It’s just a playback thing. You can turn this on for VHS movies, too,)

  It’s done to have a big contrast between the letter and its background, so you can read all the information all the time (except in edge cases, like the seconds in the video you show, the background is mostly 50-50 with black and white, so the text is kept in black, and can be a bit hard to read)
