Findings
IC-048
Existing video LLMs (TimeChat, VTG-LLM, Momentor, Hawkeye) show limited zero-shot video temporal grounding capability and struggle to improve with fine-tuning
IC-049
GPT-4o shows strong performance on some E.T.Bench event-level tasks (RVQ: 57.7, VHD: 56.9) but very weak performance on others (EPM: 4.5, TAL: 20.0)
IC-050
GPT-4o achieves 53.33 overall on Event-Bench with strong event description (57.50) and counter reasoning (63.44) but weaker episodic reasoning (37.33)
IC-051
Qwen2-VL (7B) achieves 0.0 on DVC, DVC SLC, and TEM tasks on E.T.Bench
