Before you make a lyric video
Lyric video creation in the current iOS app requires a completed full AI Auto-Sync song and your own background image. AI provides line timing; word or group karaoke timings are created manually for ASS / Enhanced LRC export.
Quick format comparison
| File | Timing | Good for | Appearance |
|---|---|---|---|
| LRC | Line start times | Music player lyrics | Depends on player |
| SRT | Start and end for each caption | Video editor subtitles | Basic styling |
| ASS | Event intervals and karaoke timing tags | Styled subtitles and karaoke | Advanced placement and styles |
LRC: a timestamp at the start of each line
[00:12.40]First lyric line
[00:16.80]Second lyric lineBasic LRC is compact and readable. Some enhanced variants offer finer-grained timing, but a simple line-start LRC does not automatically produce per-syllable karaoke.
SRT: start and end intervals
1
00:00:12,400 --> 00:00:16,700
First lyric lineSRT is designed for time intervals rather than lyric-line starts. It is commonly imported into subtitle and video workflows.
ASS: advanced styling and karaoke
Advanced SubStation Alpha (.ass) can define styles, on-screen position and karaoke effects. Tags such as \k express durations in centiseconds. Actual behavior depends on the subtitle renderer and its supported features.
Which file should I choose?
- Use LRC when your music player supports scrolling lyrics.
- Use SRT for video editor subtitle timelines.
- Consider ASS for styled karaoke where the renderer supports it.
LyricTap's free web editor exports LRC, SRT and TXT. ASS is explained here for comparison; the browser studio does not currently export ASS.
