 # SANA-WM-Bench
 
 Minimal 80-scene, 60s SANA-WM benchmark release. It contains the 80 conditioning images, fixed public scene set, simple/hard 60s Sana-WM camera trajectories. Scene IDs are anonymized within each category as 001-020. It intentionally excludes 24s settings, non-Sana-WM export formats, baseline outputs, and generated videos.
+
+## Image Provenance
+
+All conditioning images in `images/` are AI-generated using Google's Nano Banana
+(Gemini native image generation). The images are synthetic benchmark inputs and
+are not real-world photographs.
