Its page says results are for research, academic or personal use only, and that commercial use is prohibited. For commercial use it points to Sync Labs. Do not use it for ads you run. ## A worked example Say you have one 30-second Hindi ad and want 4 more language versions. On Sync Creator with the lipsync-2 model, each version costs 30 seconds x $0.05 = $1.50. Four versions cost $6. Add the $19 plan and you pay $25, about INR 2,125 at INR 85 to the dollar. This covers lip sync only. You still need a translated script and a voice. See [AI dubbing](/glossary/ai-dubbing) and [how to dub ads into Hindi](/guides/how-to-dub-ads-into-hindi). ## How to choose 1. **Test your own clip.** Use the free plan or trial on a real ad, in your language, with a face turned slightly sideways. 2. **Count seconds.** Per-second tools suit short ads. Minute packs suit long videos. 3. **Check rights.** Read the terms before you run the result as an ad. Read [what AI lip sync is](/glossary/ai-lip-sync).

It has a production canvas that publishes to Meta. See [the production canvas](/features/production-canvas). ## FAQ ### Is there a free AI lip sync tool? HeyGen's free plan and Rask AI's free trial let you test it. Wav2Lip is free but not for commercial use. ### Does lip sync work for Hindi and other Indian languages? Test it on your own clip first. Tool pages list languages in different ways, and quality varies by voice and face. ### Do I need lip sync for dubbed ads? Not always. Voiceover with subtitles can work for ads where the speaker is off screen. Use lip sync when a face talks to the camera. --- - [More AI tools articles](https://marxx.ai/library-best/category/ai-tools) - [All articles](https://marxx.ai/library-best)
