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 SUB_MICRODVD

MicroDVD is a frame-based subtitle format, which means its timings are based on video frame numbers rather than timestamps. For example, a line might be defined to appear from frame 1000 to frame 1050. This can be very precise, but it also means the subtitle file is tied to a specific video file with a specific frame rate. If the frame rate changes, the subtitle timing will be incorrect.

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.

Why use frame numbers instead of time?

Frame-based timing can be very useful for video editors who work on a frame-by-frame basis. However, for general distribution and playback, time-based formats like SRT are much more flexible and reliable, as they are not dependent on the video's frame rate.

What happens if I use a MicroDVD file with the wrong frame rate video?

The subtitles will go out of sync. For example, if the subtitle file was created for a 25 fps video, but you play it with a 29.97 fps video, the subtitles will appear progressively earlier or later as the video plays.
