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

  Doesn’t seem like enough resolution for an outline to work.

    Plus it’s probably more complex to engineer multi-colour (well, two colour) font rendering onto the video. Getting the background brightness for each character is as simple as adding all the pixel rgb values together and threshold in. It doesn’t need to be very accurate.

  Also this conveniently doesn’t show white color background.

    Still pretty readable on a white background. The black outline sees to that.

  That takes up more space than they care to give it

  Yellow with blue line us even better for CCTV use imo.
