我们介绍了VideoPoet,这是一个语言模型,能够从大量的条件信号中合成高质量的视频,并配有相应的音频。VideoPoet采用了一个仅解码器的Transformer架构,可以处理多模态输入,包括图像、视频、文本和音频。训练协议遵循大型语言模型(LLM)的协议,包括两个阶段:预训练和任务特定的适应。在预训练期间,VideoPoet在自回归Transformer框架中结合了多模态生成目标的混合。预训练的LLM作为基础,可以适应各种视频生成任务。我们展示了实证结果,证明了该模型在零样本视频生成方面的最新能力,特别强调了VideoPoet生成高保真度动作的能力。项目页面:http://sites.research.google/videopoet/
We present VideoPoet, a language model capable of synthesizing high-quality video, with matching audio, from a large variety of conditioning signals. VideoPoet employs a decoder-only transformer architecture that processes multimodal inputs -- including images, videos, text, and audio. The training protocol follows that of Large Language Models (LLMs), consisting of two stages: pretraining and task-specific adaptation. During pretraining, VideoPoet incorporates a mixture of multimodal generative objectives within an autoregressive Transformer framework. The pretrained LLM serves as a foundation that can be adapted for a range of video generation tasks. We present empirical results demonstrating the model's state-of-the-art capabilities in zero-shot video generation, specifically highlighting VideoPoet's ability to generate high-fidelity motions.
