📰 News

• [2024.11.01] 🔥 We are excited to announce the release of trace-uni, which has been enhanced by incorporating additional general video understanding data from a subset of LLaVA-Video-178k. Our results indicate that trace-uni outperforms trace in both VTG tasks and general video understanding tasks.
• [2024.10.19] 🔥 We release trace-retrieval by forcing the predicted timestamps to be align with the input frame timestamps. Results show trace-retrieval achieve better performance on dense video captioning tasks.
• [2024.10.10] 🔥 Our code and paper are released!
• [2024.10.10] 🔥 Our checkpoints are available now!

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.
