About SSA
SubStation Alpha (SSA) is the predecessor to the more feature-rich ASS format. It was one of the first subtitle formats to allow for basic styling, including control over fonts, colors, and text position. While it has largely been superseded by ASS, it laid the groundwork for advanced subtitle scripting and is still supported by many players that support ASS.
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.

Frequently Asked Questions
Should I use SSA or ASS?
You should almost always choose ASS over SSA for new projects. ASS is fully backward-compatible with SSA and contains a much larger and more powerful feature set. SSA is primarily of interest for compatibility with very old files or legacy workflows.
What can SSA do that SRT cannot?
Unlike SRT, SSA allows you to define specific styles for your subtitles, such as the font family, font size, primary and secondary colors, and basic positioning on the screen. However, its capabilities are much more limited compared to its successor, ASS.
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.
