MBench Data
This repository contains the evaluation data released with MBench.
MBench-A: 547 action-conditioned evaluation samples.MBench-T: 493 base cases, expanded into 684 condition-level evaluation items.
Structure
Each benchmark follows the directory protocol expected by the MBench evaluator:
MBench-{A|T}/
├── dataset.yaml
├── samples/{subset}/{sample_id}/sample.json
└── models/{model_id}/
├── model.yaml
├── samples.jsonl
└── outputs/{subset}/{sample_id}/{condition_id}/video.mp4
The exact evaluation items available for each model are listed in
models/{model_id}/samples.jsonl.
In MBench-T, the 493 base cases consist of 293 non-causal samples and 200 causal samples. The causal samples are expanded into 200 camera-motion, 100 occlusion, and 91 dimming conditions, producing 684 condition-level items in total.
