InfiniTalk is an AI talking head model that generates avatar videos of unlimited length from a single portrait photo and audio input.

Is there a maximum video duration?

No hard limit. InfiniTalk uses streaming generation to produce videos of any length. Practical limits depend on your audio length and credits balance.

What is InfiniTalk Fast?

InfiniTalk Fast is a speed-optimized variant that generates videos approximately 2× faster with minimal quality reduction. Ideal for drafts and quick previews.

Can I use my own voice recordings?

Yes, upload any audio file (MP3, WAV, M4A). You can record your own voice, use AI-generated speech, or use any other audio source.

Does it work for non-English audio?

Yes. InfiniTalk is language-agnostic — it synchronizes lip movements to any language audio since it works on audio waveforms, not text.
