+# FairDeep-Fake Bench: controlled synthetic videos
+
+Fully AI-generated talking-head clips for **evaluating the demographic fairness of deepfake detectors**.
+Every person depicted is synthetic: no real identities, no identity LoRAs, no face-swap of real people.
+
+## Design
+- 56 demographic cells (FairFace-compatible): 7 perceived race × 2 gender × 4 age bands
+  (18-29, 30-44, 45-59, 60+). Labels are the **intended perceived presentation**,
+  not self-identification.
+- **Counterfactual groups**: each group fixes scene, lighting, behaviour, attire slot, camera,
+  duration and seed, and renders it once per cell. Every cell therefore sees an identical
+  distribution of confounds.
+- Main run `synthetic/ltx23/`: LTX 2.3 22B dev (bf16), 36 groups × 56 cells = **2,016 clips**,
+  1280×704, 24 fps, ~6 s, with generated audio, 20 steps, cfg 3.0.
+
+## Files
+- `synthetic/<model>/<race>_<gender>_<age>/<prompt_id>.mp4`: clip
+- `....json` next to each clip: full spec, rendered prompt, generation and provenance record
+- `metadata.csv`: one row per clip (demographics, scene, seed, prompt, technical QC columns `qc_*`)
+
+## Technical QC
+`qc_pass` covers container conformance, frozen/black/stalled frames and letter/pillarboxing
+(1,885 / 2,016 pass). Model-based gates (FairFace/MiVOLO compliance, ArcFace identity
+leakage) are not applied yet.
+
+## Generation code
+Private GitHub repo `fairdeep-datagen` (ComfyUI-based, reproducible from the sidecar seeds).
+
+## Intended use
+Research on deepfake-detector fairness only. Not for training generators to impersonate people.
