From Aegisub Manual
Wikipedia's definition of typesetting : "Typesetting involves the presentation of textual material in graphic form on paper or some other medium." In a subtitling context, this means three things:
- Presenting (a translation of) the spoken dialogue to the viewer in an easily readable and visually pleasing form.
- Translating any foreign-language background texts (such as episode titles, scene information like time/place and other plot-important writings on things in the background) and presenting the translation to the viewer, preferably so that it appears that the translation was there all along (yet retaining readability).
- Designing other texts (logotypes, karaoke, etc. etc.) that should be displayed on the video.
Particularly in the fansub community, the word "typesetting" usually refers to the second or third of these three.
This page will attempt to give you an introduction to subtitle typesetting. Unfortunately good taste is hard to teach, but we will do our best.
The main goal of dialogue typesetting is legibility; everything else is just icing on the cake. There's no point in having subtitles if the viewer can't read them. Remember that subtitles frequently require quite fast reading, so ease of recognition is vital. Some guidelines for good legibility:
- Use a plain, uncluttered, no-nonsense typeface. Sans-serif fonts (or if you insist on serifs, "slab serif" fonts) are generally preferable, especially at low video resolutions, since the serifs tend get blurred out, which naturally looks bad. Too thin fonts are also to be avoided. Small caps fonts are bad because the ascenders/descenders of help recognition of words. Using tried and trusted faces such as Helvetica, Arial or Verdana is not a bad thing; if you want something that looks less "boring" but still readable try a sans-serif font of the "humanist" variety, such as Calibri.
- Use a well-defined but not too thick border. The color is important; the higher the contrast against the main color the better. The white main color/black border combo is well tried and trusted. Shadow is optional; if you use it consider setting it to half-transparent black; solid black tends to hurt legibility.
- Use big friendly letters with comfortable margins; usually subtitles need to be bigger than you think to be easily readable, particularly on a TV screen (since the viewing distance on a TV is usually 2-3 meters, compared to 0.3-0.6m for a computer screen). If you plan on showing your subtitles on a TV you also need to take overscan into account; Aegisub has an overscan mask feature (see working with video) that can help you with this. Also consider the aspect ratio of the video; 16:9 or wider aspect ratios give you the opportunity to have longer lines at the expense of vertical space.
- Make sure that no more than two lines of text are visible at a time (exceptions can be made at times where there are a lot of people talking at the same time). Sometimes you can compress the text horizontally a bit to squeeze it in; at other times you just have to split the text block into two different lines and display one after the other.
Sign typesetting (translating various background text) can usually be accomplished with ASS, but commercial programs like Adobe AfterEffects are becoming an increasingly popular alternative, since the holy grail of sign typesetting is to make the subtitle look like it's a part of the image that was always there. How to get there from here will not be discussed in detail on this page (see the typesetting tutorial), but here are some pointers:
- Is the sign important to the plot? You shouldn't try to go around translating every single sign there is, or you'll go insane (and the end result will probably be unreadable anyway).
- Frequently, the text of a plot-important sign (such as a letter) is actually read out loud in the dialogue; if this is the case you should consider skipping the sign typeset because having both text and dialogue may overload the viewer with information.
- Will you be able to make the translation easily legible? For example, if you have very little space available to squeeze it in on, consider putting a translation note as a normal "toptitle" instead.
