## 🎯 Learning Objectives
By working through this exercise, you will:
- Reproduce baseline behavior of a video-language model (**VTimeLLM**, CVPR 2024 Highlight).
- Observe the limitations of existing approaches in temporal reasoning and coherence.
- Implement and experiment with **VidChain's improvements** using M-DPO.
- Run inference on videos to generate **dense temporal captions (Dense Video Captioning)**.
- Evaluate how preference alignment improves performance over baselines.
- Discuss potential strategies for ensembling different reasoning paths of VidChain's CoTasks.
