About

Audio-driven multi-person conversational video generation - Upload audio files and a reference image to create realistic conversations between multiple people

Example Output

Prompt:

"In a casual, intimate setting, a man and a woman are engaged in a heartfelt conversation inside a car. The man, sporting a denim jacket over a blue shirt, sits attentively with a seatbelt fastened, his gaze fixed on the woman beside him. The woman, wearing a black tank top and a denim jacket draped over her shoulders, smiles warmly, her eyes reflecting genuine interest and connection. The car's interior, with its beige seats and simple design, provides a backdrop that emphasizes their interaction. The scene captures a moment of shared understanding and connection, set against the soft, diffused light of an overcast day. A medium shot from a slightly angled perspective, focusing on their expressions and body language"
