## Overview

In this work
- We model the videos by a series of events, and propose causal event modeling framework to capture videos' inherent structure.
- We present a novel task-interleaved video LLM model, TRACE, tailored to implement the causal event modeling framework through the sequential encoding/decoding of timestamps, salient scores, and textual captions.
