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.

About JSON

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. While not a traditional subtitle format itself, it is an excellent way to store and transmit structured subtitle data. Each subtitle cue can be an object with properties for start time, end time, text content, and any custom metadata.

Frequently Asked Questions

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.

Can a media player play a JSON subtitle file?

No, standard media players like VLC or QuickTime cannot directly play a JSON file as a subtitle track. JSON is a data format that would need to be processed by a custom web application or script to display the subtitles over a video.

Why would I convert subtitles to JSON?

Converting subtitles to JSON is extremely useful for web developers and data processing. It allows you to easily load subtitle data into a web application, manipulate it with JavaScript, integrate it with other APIs, or store it in a database in a structured way.
