Questions
Frequently asked questions
Does the optimizer understand sentence meaning?
It wraps at word boundaries by length; an editor should still review phrasing and natural-language breaks.
Will timing change?
No. Cue start and end timestamps remain unchanged.
Can a single long word exceed the limit?
Yes. Words are not split, which avoids introducing unnatural hyphenation.
