Transifex supports three subtitle file formats: SubRip, SubViewer, and YouTube captions. With the Video Subtitle Editor, you can translate SubRip and SubViewer files while watching the video play in the translation editor.

SubRip (.srt)

SubRip is the native subtitle format of the SubRip program. It is one of the most used formats for subtitles, supported by most software video players, many subtitle creation/editing tools and some hardware home media players. YouTube also supports .srt files.

An entry in a .srt file may contain certain HTML tags, like <i>.

Also, keep in mind that the encoding of your file needs to be UTF-8. If your file's encoding is different, then you can convert this accordingly following the process described here.


Titles and descriptions in .srt

If you need to translate titles and descriptions in SRT files, please follow the steps below:

  1. Include both title and description in your localization file as follows:

    ex.

  2. In order to prevent translators from editing the text inside brackets, you can:

    • Click SubRip subtitles (.srt) checks

    • Click Set up placeholder delimiters

    • Create a new placeholder as follows:

    Created-Placeholder.PNG#asset:9476

  3. As a result, you will have the strings in the Editor like this:

    Subtitles in editor with Placeholder


SubViewer (.sub)

SubViewer files (.sub) are the native subtitle format of the SubViewer utility.


YouTube Captions (.sbv)

.sbv is the file format outputted by YouTube's Automatic Timing feature which automatically creates timed captions based on a transcript.
