Frequently Asked Questions

Can SadTalker work with low-resolution images?
While high-res images yield best results, the AI can enhance details in lower-quality photos – just expect softer edges in the final animation.

Does it support multiple languages?
Absolutely! The audio analysis works with any language, dialect, or even made-up fantasy speech patterns.

How realistic do the animations look?
Realism depends on your input, but the AI excels at natural lip-syncing and subtle expressions – many users say it’s "uncanny valley-breaking."

Can I customize specific facial features?
You bet! Adjust jawline movement, eye dilation, and even cheek puffiness to match your character’s personality.

What about long audio files?
The app handles extended tracks seamlessly – think audiobook narrations or hour-long virtual assistant videos.

Does it work with singing voices?
That’s one of its superpowers! Upload karaoke tracks or vocal melodies, and watch mouths form precise phonemes for lyrics.

How much control do I have over timing?
You’ll get frame-by-frame editing in the pro version, but even basic controls let you delay expressions or stretch mouth movements.

Is there an ethical use policy?
While the tech opens creative doors, the developers strongly discourage deepfake misuse – always get consent when animating real people’s faces.
