Abstract

The proliferation of hour-long videos (e.g., lectures, podcasts, documentaries) has intensified demand for efficient content structuring. However, existing approaches are constrained by small-scale training with annotations that are typical short and coarse, restricting generalization to nuanced transitions in long videos. We introduce ARC-Chapter, the first large-scale video chaptering model trained on over million-level long video chapters, featuring bilingual, temporally grounded, and hierarchical chapter annotations. To achieve this goal, we curated a bilingual English-Chinese chapter dataset via a structured pipeline that unifies ASR transcripts, scene texts, visual captions into multi-level annotations, from short title to long summaries. We demonstrate clear performance improvements with data scaling, both in data volume and label intensity. Moreover, we design a new evaluation metric termed GRACE, which incorporates many-to-one segment overlaps and semantic similarity, better reflecting real-world chaptering flexibility. Extensive experiments demonstrate that ARC-Chapter establishes a new state-of-the-art by a significant margin, outperforming the previous best by 14.0% in F1 score and 11.3% in SODA score. Moreover, ARC-Chapter shows excellent transferability, improving the state-of-the-art on downstream tasks like dense video captioning on YouCook2.

Brief Introduction

We introduce ARC-Chapter: a large-scale model from Tencent ARC Lab for deep video understanding and structured chapter generation. ARC-Chapter automatically analyzes videos that have a clear narrative or semantic structure, segmenting them into meaningful chapters, identifying precise timestamps, and generating summaries for each part. Our goal is to let users browse videos like they read a document—getting straight to the point—while empowering platforms and creators with more efficient ways to manage and distribute their content.

Overview: An illustration of the capabilities of our video chaptering model. Given a video, our model is able to generate timestamped chapters with three-level structured output: 1) Short Title - a concise label summarizing each chapter; 2) Structural Chapter - a detailed, structured annotation for each chapter, including a rewritten comprehensive title, an abstract summarizing the core content, and an introduction describing key details and highlights; and 3) Timestamp-Aligned Video Description - fine-grained descriptions aligned with precise temporal boundaries. This hierarchical structure facilitates an efficient and precise understanding of video content.
Video Annotation Pipeline: Overview of our automatic video annotation pipeline for hierarchical chaptering and summarization. We extract visual captions (OCR included) from sampled video frames and ASR transcripts from audio. These outputs are temporally aligned and interleaved into a unified multimodal transcript. This transcript, together with original chapter markers, is processed by an LLM to produce structured chapters and timestamp-aligned video descriptions.
