Syncing fast rap, live vocals or long instrumental sections

The sync needs lyrics that match the recording. Fast words, layered voices and long gaps are reasons to check the result carefully, not a reason to assume every line is right.

Give the sync a clear starting point

1. Use the final recording you want in the video.
2. Write every sung line in order, including repeats.
3. Mark backing words as ad-libs rather than mixing them into the lead line.
4. After analysis, listen to the amber lines and any crowded passages.
5. Use the guided check or 'Tap along' to correct them.

An amber line can mean the vocal is hard to hear, a word is unusually long or the timing is uncertain. It is a prompt to listen, not a verdict on your recording.

Styles handle gaps differently. Play a long intro or instrumental section before choosing a style. An instrumental-only song cannot follow the normal flow that requires pasted lyrics.

There is no promised accuracy rate for a genre or recording type. Check fast, layered and heavily processed vocals by listening, even when a line has no warning.

If you auto-detect your lyrics

Detecting sung words is a different task from timing supplied text. Accents, vocal effects, overlapping singers and quiet phrases can affect the result. Check the detected words in Sync even if the timing looks right. Accurate pasted lyrics are still a useful starting point. Read about auto-detecting lyrics.
