Outline

This paper points out that despite the advances in large-scale language models (LLMs) and multimodal augmentation (MLLMs), it is still difficult to effectively process and understand video content lasting for minutes or hours. Although recent models such as Video-XL-2 have improved efficiency, and advances in positional encoding such as HoPE and VideoRoPE++ have improved spatiotemporal understanding, there are still computational and memory constraints in processing the massive visual tokens in long video sequences. Therefore, this paper proposes “Infinite Video Understanding,” the ability to continuously process, understand, and reason about infinite-length video data, as the next goal of multimedia research. This will drive innovations in areas such as streaming architectures, persistent memory mechanisms, hierarchical and adaptive representations, event-driven reasoning, and novel evaluation paradigms. Based on recent research in long/ultra-long video understanding and related fields, this paper presents key challenges and major research directions to achieve this transformative capability.

Takeaways, Limitations

Takeaways:
We propose a new research goal called Infinite Video Understanding, which suggests a direction for the development of multimedia and AI research.
It can breathe new life into research areas such as streaming architectures, persistent memory mechanisms, hierarchical and adaptive representations, event-driven reasoning, and novel evaluation paradigms.
It can foster the development of new approaches and technologies for long-term video understanding.
Limitations:
Infinite Video Understanding is a very ambitious goal, and the technical challenges to achieve it are significant.
The proposed research direction is not specific and is rather comprehensive, so it may be difficult to apply it to actual research.
The absence of effective evaluation methodologies for Infinite Video Understanding can hinder the progress of research.
