When and Where to Look: Adaptive Visual Evidence Scheduling for Efficient Long Video Understanding

- What happened
- EcoFrame framework adaptively selects video frames for vision-language models using entropy-based budget scheduling and attention-guided search instead of static frame selection.
- Why it matters
- Matters for engineers building long-video understanding systems who need faster inference without sacrificing accuracy on benchmarks like Video-MME and LongVideoBench.
- Watch out
- Training-free approach requires the VLM to already be deployed; unclear how well entropy signals generalize across different model architectures and video domains.
