+# NExT-CF: Counterfactual Entity-Removal Benchmark for VideoQA
+
+NExT-CF is a benchmark of 570 counterfactually edited videos
+derived from NExT-QA, used to probe whether Video Question Answering
+models rely on visual evidence or language priors. Each video has a
+target entity removed via diffusion inpainting (DiffuEraser), and the
+corresponding QA pairs are carried over from NExT-QA.
+
+## Tiered structure
+
+- **Tier 1 (direct):** 389 edited videos in `tier1_edited_videos/`.
+  Source clips are CC-BY, CC-BY-SA, CC-BY-NC, or CC-BY-NC-SA. Edited
+  videos are released under CC-BY-NC-SA 4.0.
+- **Tier 2 (reproducible):** 181 entries in `reproduce_tier2/`.
+  Source clips are CC-BY-ND or CC-BY-NC-ND, whose "NoDerivatives"
+  clause prohibits redistribution of modified versions. To stay
+  license-compliant, we ship only the SAM3 prompt and QA pairs for
+  these clips; run `reproduce_tier2/reproduce.sh` to regenerate the
+  edits locally from the unmodified NExT-QA sources.
+
+All 570 clips are included in the evaluation benchmark.
+
+## Contents
+
+| File | Description |
+|---|---|
+| `metadata.json` | All 570 entries — id, tier, prompt, license, QA |
+| `tier_assignment.csv` | Per-clip tier + original license |
+| `tier1_edited_videos/` | 389 edited MP4s |
+| `reproduce_tier2/tier2_manifest.csv` | 181 ND clips, one row each |
+| `reproduce_tier2/reproduce.sh` | Regeneration wrapper |
+| `ATTRIBUTION.csv` | Flickr credits for all clips (mandatory under CC-BY) |
+| `LICENSE` | CC-BY-NC-SA 4.0 (tier-1 edited videos) |
+| `LICENSE-METADATA` | CC-BY-SA 4.0 (metadata, prompts, QA) |
+
+## Attribution
+
+Source clips are from YFCC100M via NExT-QA. Per-clip photographer
+credit is in `ATTRIBUTION.csv`. This dataset requires citing both:
+
+- NExT-CF (this dataset) — see CITATION.cff
+- NExT-QA: Xiao et al., "NExT-QA: Next Phase of Question-Answering to
+  Explaining Temporal Actions", CVPR 2021.
+
+## Reproducing tier-2 edits
+
+```bash
+# 1. Download NExT-QA videos separately (license permits redistribution
+#    of originals; see https://github.com/doc-doc/NExT-QA)
+export NEXTQA_DIR=/path/to/NExTVideo
+
+# 2. Clone the NExT-CF code repo
+git clone https://github.com/<owner>/nextcf-code
+export CODE_DIR=$(pwd)/nextcf-code
+
+# 3. Run the reproduction script
+bash reproduce_tier2/reproduce.sh
+```
+
+Takes roughly 15 GPU-hours for all 181 clips on an RTX 6000 (fp16).
+
+## Ethics and limitations
+
+- Synthetic edits from diffusion models may contain artifacts.
+- Source distribution inherits any biases of NExT-QA and YFCC100M.
+- This dataset is research-only (NC clause). Commercial use is not permitted.

For each video, a target entity is removed via SAM3 segmentation and DiffuEraser diffusion inpainting, and the corresponding QA pairs are carried over from NExT-QA. The release uses a two-tier structure: 389 edited videos ship directly (tier 1, CC-BY-NC-SA 4.0); 181 videos whose source clips carry a CC NoDerivatives clause ship as metadata plus a local reproduction script (tier 2). All 570 clips are included in the evaluation benchmark.",

+    "Positive: supports rigorous evaluation of video-language models' reliance on visual evidence, helping surface models that rely on priors rather than perception. Risk: synthetic edits could be misused for training deceptive content; the non-commercial license and research-only framing mitigates this. Benchmark does not contain harmful content beyond what is in the NExT-QA source."
