InfiniteTalk 常見問題
What inputs does InfiniteTalk require?
A portrait image (face clearly visible) and an audio file. The model generates a video of the portrait speaking the audio with lip sync.
How accurate is the lip sync?
InfiniteTalk produces frame-accurate lip sync matched to the input audio, with natural mouth shapes for speech sounds.
Does it animate more than just the mouth?
Yes — the model generates natural head movement, eyebrow expressions, and subtle facial micro-expressions synchronized with speech patterns.
What audio formats are supported?
MP3, WAV, AAC, MP4, and OGG are supported formats. The audio drives both lip sync timing and expression intensity.
Is there a maximum video length?
InfiniteTalk supports generating long-form talking head video — the output length matches the input audio duration.
我應該先用邊個版本？
先選最平而且符合你質素要求的版本。大多數團隊會先用快速版本，之後再升級到 pro 用於正式生產。
