Fonts

Fonts of different types and sizes look different across video displays and resolutions. Therefore, choosing the right font size is critical to ensure readability on the final encoded video.

Some broadcasters recommend that as a rule of thumb font sizes to be displayed on an HD 1920 x 1080 video should be about 80% of the sizes used in SD. For example, you have been using a font that is 23 scan lines high on SD NTSC. First we consider the ratio of the HD / SD heights: 1080 / 486 = 2.22 and 80% of 2.22 is 1.776. Use 1.776 as the font scaling factor. That means that our new font size is 23 x 1.776 = 41 scan lines high (with rounding.)

Always check how your titles look in the target player and display to be sure that the text is readable and that aesthetics translate.
