Frequently Asked Questions

What is AI Lip Sync?

AI Lip Sync is a technology that analyzes an audio track (like a voiceover or translation) and automatically generates realistic, corresponding lip movements on a person's face in a video.

Can I use this to translate my videos?

Yes. This is one of the most popular uses. You can upload your video and a new audio file (e.g., a Spanish dub) and our AI will generate perfect lip sync for the new language, creating a professional AI video translation.

Can I make a talking photo or avatar?

Absolutely. Instead of a video, you can upload a still image (a portrait, avatar, or drawing) along with an audio file. The tool will animate the face in the photo to create a high-quality 'talking photo' video.

What kind of video works best?

For the most realistic results, use a clear, well-lit video where the speaker is facing forward. Videos with profiles, obscured mouths, or very low resolution may see reduced quality.

How are credits charged for lip sync?

Pricing is based on mode, resolution, and final video duration. Standard mode costs 3 credits per second. Pro mode costs 45 credits per second at 480p or 90 credits per second at 720p. Your total credits are calculated as mode rate × video seconds.

Can I use the generated videos commercially?

Yes, you can use the videos created with our tool for commercial purposes, provided you own the rights to the original video and audio content. Please adhere to Toolplay's terms of service.
