(SVScript) Timestamp lyrics

Had an annoying problem, which is to approximate the timestamp of the lyrics when I want to insert lyrics into my videos.

Traditional method is to literally play the song live while editing the words and timing one by one.

If you had already written your lyrics in Synthesizer V, using the script below will return you the timestamp for each lyric.

• Timestamp automatically adjusts based on the BPM of the project.
• Timestamp returns for each syllable. (No clustered sentences like a transcript. I don't want to over engineer it)
• Offset parameter if your video/music is not in sync with the score.

const SCRIPT_TITLE = "Timestamp Extractor";
var message = "Retrieves the timestamp for each lyric.\n" +
"\n" +
"Use offset if your video/music is not in sync with the score.\n" +
"\n" +
"Timestamp automatically adjusts based on the BPM of the project.\n" +
"\n" +
"Script has not tested with tempo automation. Use at your own risk.";
