Is text-to-video lip sync free to try?

Yes. You can generate without an account and outputs carry no watermark. Free generations are limited to 133 characters of script; downloads require a free sign-in and use a low-resolution copy unless you unlock the original with a Pro Video.

What video files are supported?

MP4, MOV, and WebM uploads are supported. Use a clip where one face is clearly visible while speaking — good lighting and a steady framing give the cleanest sync.

How long can the new script be?

133 characters on the free tier, 800 characters on Starter, and up to 16,000 characters on Pro. The plan limit applies to the typed script, not the length of the uploaded video.

Can I keep the original speaker's voice?

Yes. Clone the speaker's voice from a short sample of the original footage, then type the new script — the retake speaks in the same voice.

Will the result have a watermark?

No. Outputs are watermark-free on all plans. Free downloads are low-resolution; original resolution unlocks with a Pro Video or a paid plan.

Does it work for translated scripts?

Yes. Type the script in the target language and pick a voice for that language (or a cloned voice). The lips re-sync to the new language's phonemes.

How to re-script a talking video

1
Upload a face video
Add an MP4, MOV, or WebM clip with one clearly visible speaking face — a past recording, a UGC clip, or an avatar render.
2
Type the new script
Write the replacement dialogue. Free accounts support 133 characters; Starter raises the limit to 800 and Pro to 16,000.
3
Choose the voice
Pick a preset voice or clone the original speaker's voice from a short sample so the retake sounds natural.
4
Generate the new take
The engine re-syncs the lips to the new script and renders a watermark-free video — no reshoot required.

What people make with it

Fix mistakes without reshooting

Correct a wrong price, name, or date in an existing video by typing the fixed line instead of re-filming the whole take.

Update evergreen videos

Keep product demos and onboarding videos current when features change — swap the outdated sentences and keep the footage.

Localize spokesperson videos

Deliver the same presenter video in other languages by re-scripting it with a translated script and a matching voice.
