Convert JSON Subtitles to SCC Format
or drag and drop
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.
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.

Frequently Asked Questions
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.
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.
