Using Fonts and Creating Line Art for Video

When creating line art or selecting a font to use for a broadcast video image, you should avoid creating horizontal single-pixel lines, or using fonts that are too thin. Because video is interlaced, single-pixel lines will flicker as the field in which they appear alternates on and off. This results in “buzzing” in your graphics, with the buzzing becoming more pronounced the closer the thin areas in your image are to horizontal.

This can be lessened by adding a bit of blur or anti-aliasing to your image, but the best thing to do is to avoid single-pixel lines altogether when creating graphics for broadcast.
