> We present **MultiTalk**, an open-source audio-driven multi-person conversational video generation model with the state-of-the-art lip synchronization accuracy.
|
| 44 |
-
> Key features:
|
| 45 |
-
> - 💬 Realistic Conversations - Supports single & multi-person generation
|
| 46 |
-
> - 👥 Interactive Character Control - Direct virtual humans via prompts
|
| 47 |
-
> - 🎤 Generalization Performances - Supports the generation of cartoon character and singing
|
| 48 |
-
> - 📺 Resolution Flexibility: 480p & 720p output at arbitrary aspect ratios
|
| 49 |
-
> - ⏱️ **Long Video Generation**: Support video generation up to 15 seconds

## Method
|
| 60 |
-
We propose a novel framework, MultiTalk, for audio-driven multi-person conversational video generation. We investigate several schemes for audio injection and introduce
|
| 61 |
-
the Label Rotary Position Embedding (L-RoPE) method. By assigning identical labels to audio embeddings and video latents, it effectively activates specific regions within the audio cross-attention
|
| 62 |
-
map, thereby resolving incorrect binding issues. To localize the region of the specified person, we introduce the adaptive person localization by computing the similarity
|
| 63 |
-
between the features of the given region of a person in the reference image and all the features of the whole video.
