dingxingdi Skill: long-video-summarization
1. Capability Definition & Real Case
- Professional Definition: The capability to compress long-form video into a faithful global account that preserves the major events, temporal progression, and outcome without collapsing into vague topical language or omitting decisive developments.
- Dimension Hierarchy: Long-Horizon Reasoning->Global Content Integration->long-video-summarization
Real Case
[Case 1]
- Initial Environment: A 100-minute football match video with multiple attacks, substitutions, and momentum swings. The user asks about the second half rather than about one isolated play.
- Real Question: What happens in the second half of the game?
- Real Trajectory: Segment the second half into major phases, identify turning-point actions, suppress low-impact repetitions, and compose a chronologically ordered summary that preserves the decisive score-changing events.
- Real Answer: As the game progressed towards its final stages, Liverpool's offensive pressure gradually intensified. A free kick from Liverpool leading to an own goal in the penalty area later changed the game's momentum, Liverpool once again scored another goal, resulting in a 2-0 victory.
- Why this demonstrates the capability: The answer requires broad coverage and selection of high-salience developments across a long interval. This tests whether the agent can preserve temporal progression and outcome while compressing large amounts of video evidence.
Pipeline Execution Instructions
To synthesize data for this capability, you must strictly follow a 3-phase pipeline. Do not hallucinate steps. Read the corresponding reference file for each phase sequentially:
