About TXT
A plain text (.txt) file is the simplest possible format, containing only raw text characters without any timing or styling information. When used in the context of subtitles, it typically represents a transcript of the audio. To be used as subtitles, this transcript would need to be processed by another tool to add the necessary timestamps to sync the text with the video.
About SUB_SUBVIEWER
SubViewer (.sub) is one of the earliest popular subtitle formats. It is a simple, time-based text format. There have been two major versions, SubViewer 1.0 and 2.0. Version 2.0, which is more common, uses a '[region]' section to define metadata and then lists subtitles with timestamps. Its simplicity led to wide support, but it lacks any styling features.

Frequently Asked Questions
How can I turn a TXT transcript into an SRT file?
This process is called 'timing' or 'syncing'. It requires specialized software where you can load the video and the text file, and then go through the video, marking the start and end times for each line of dialogue. Many professional subtitle editors offer features to help with this process.
When is a plain TXT file useful?
A plain text file is very useful for creating a simple, readable transcript of a video for reference, for search engine optimization (SEO), or as the first step in a translation workflow before the text is timed.
My .sub file doesn't work. Why?
The '.sub' file extension is very generic and is used by several completely different and incompatible subtitle formats, including the text-based SubViewer and the image-based VobSub (for DVDs). If your file isn't working, it's likely because your player is expecting a different '.sub' format. Our converter can intelligently distinguish between them.
Is SubViewer still a good format to use?
For new projects, SRT is a much better choice. It's just as simple but has even wider and more reliable support across all modern platforms and players. SubViewer is mostly relevant for compatibility with older files.
