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 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

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 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.
