About LRC
LRC is a format designed to display synchronized lyrics for audio files, most commonly used by music players and karaoke software. The format is a simple text file with a timestamp at the beginning of each line of lyrics. As the audio plays, the player displays the line of text that corresponds to the current time, creating a simple but effective karaoke-style experience.
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
Can I use LRC files for video subtitles?
LRC is not suitable for video subtitles. It only has a start timestamp for each line and no end time, meaning the text would remain on screen until the next line appears. It's specifically designed for the line-by-line nature of song lyrics and lacks the features needed for proper dialogue subtitling.
What is the difference between simple and enhanced LRC?
Simple LRC format provides a timestamp for each line. Enhanced LRC format adds the ability to have timestamps for each word within a line, allowing for a more precise word-by-word highlighting effect in karaoke applications.
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.
