Questions
Text to video lip sync questions
Can I write any script?
You provide the wording and must have permission to use the video and voice. Keep it within the short speech limit and review the final result.
Does this translate a video?
No. It synthesizes the line you type and matches that speech to one visible speaker. It is not a translation or multi-speaker dubbing tool.
Can I use my own saved voice?
Signed-in users can choose a ready saved My Voice in Type text. Do not clone or use a voice without permission.
