Model overview

multitalk represents a breakthrough in audio-driven video generation by solving the fundamental challenge of multi-person conversations. Created by zsxkib, this model goes beyond traditional talking head generators that only animate single speakers. While models like video-retalking and dreamtalk focus on lip synchronization for individual speakers, multitalk generates realistic conversations between multiple people with natural interactions and precise audio-person binding. The model introduces Label Rotary Position Embedding (L-RoPE) to address the complex problem of correctly matching audio streams to specific people in multi-person scenarios.

Model inputs and outputs

The model processes reference images, multiple audio streams, and text prompts to generate synchronized conversational videos. It handles both single-person and multi-person scenarios, supporting various content types from professional presentations to casual conversations.

Inputs

image: Reference image containing the person or people for video generation
first_audio: Primary audio file driving the conversation
second_audio: Optional second audio file for multi-person conversations
prompt: Text description of the desired interaction or conversation scenario
num_frames: Number of frames to generate (25-201, automatically adjusted to valid values)
sampling_steps: Quality control parameter (2-100 steps)
seed: Optional random seed for reproducible results
turbo: Speed optimization toggle for faster generation
