Video-GPT via Next Clip Diffusion
This work addresses the challenge of capturing spatial-temporal details in videos for AI applications, representing a novel paradigm rather than an incremental improvement.
The authors tackled the problem of modeling the visual world by proposing Video-GPT, which treats video as a new language and uses a next clip diffusion paradigm for pretraining, achieving state-of-the-art performance on video prediction with a score of 34.97 on the Physics-IQ Benchmark.
GPT has shown its remarkable success in natural language processing. However, the language sequence is not sufficient to describe spatial-temporal details in the visual world. Alternatively, the video sequence is good at capturing such details. Motivated by this fact, we propose a concise Video-GPT in this paper by treating video as new language for visual world modeling. By analogy to next token prediction in GPT, we introduce a novel next clip diffusion paradigm for pretraining Video-GPT. Different from the previous works, this distinct paradigm allows Video-GPT to tackle both short-term generation and long-term prediction, by autoregressively denoising the noisy clip according to the clean clips in the history. Extensive experiments show our Video-GPT achieves the state-of-the-art performance on video prediction, which is the key factor towards world modeling (Physics-IQ Benchmark: Video-GPT 34.97 vs. Kling 23.64 vs. Wan 20.89). Moreover, it can be well adapted on 6 mainstream video tasks in both video generation and understanding, showing its great generalization capacity in downstream.
