After you have subtitled/captioned a video in one language and obtained the time codes, the same time codes can be easily used for subsequent languages. In other words, once subtitles/captions are produced for one language, a translation prepared in our captioning file format is all that is needed to subtitle/caption in additional languages.
A DVD closed caption file is a binary file consisting of a number of lines - one line for each closed caption. Each line starts with a time code which is separated from the closed caption data (in binary format) by a tab character.
MacCaption and CaptionMaker create as many files as the number of subtitles. They also create a navigation file. The navigation file lists details (time code, size and position) of each subtitle.
The first item on a line is the name of the TIF file which is a computer picture file of a subtitle using a TrueType Windows font. The next two items are the in and out time codes of a subtitle. The next two items after that are width and height of a subtitle. The last two items are the position of a subtitle on a 720X480 screen.
Since the picture files are rather large, for an one hour video, the size of all the files could easily be close to 50MB. After zipping, it can be reduced to close to 2.5MB.
Note: You need a DVD authoring system to insert the subtitles/captions on the DVD. Our captioning software may be used in conjunction with a DVD authoring system to create the subtitle/caption files that your authoring system requires.
