About SCC
SCC (Scenarist Closed Caption) is a professional format used for creating Line 21 closed captions, which are the standard for broadcast television in North America. SCC files contain not just the text but also precise data on screen positioning (including roll-up and pop-on styles) and color, conforming to the CEA-608 standard. It's a critical format for broadcast accessibility compliance.
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
What is the difference between open captions and closed captions?
Open captions are 'burned' into the video itself and cannot be turned off. Closed captions (like those from an SCC file) are a separate stream of data that the viewer can choose to enable or disable from their television or player.
Can I use SCC files for web video?
While it's possible to convert SCC to a web-friendly format like VTT, SCC itself is not designed for the web. It is a broadcast-specific format. Web platforms have their own standards for accessibility and captions, with VTT being the most common.
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.
