 ## Privacy-Processed Episode Videos
 
-The `raw_videos/` directory provides one privacy-processed H.264 MP4 for every released BVN and IFN episode. Video filenames use the same `episode_id` values as the corresponding annotation records. Where a matching readable EgoBlur output is available, the file retains the original recording resolution; otherwise the corresponding processed 256×256 RGB frames are encoded as the episode fallback. Revisit episodes are not included.
-
-This release contains 7,721 original-resolution EgoBlur videos and 3,972 256×256 frame-derived fallbacks. See `raw_videos/README.md` and `raw_videos/manifest.json` for the exact source type, fallback reason, and resolution of each episode.
+The episode video release is temporarily unavailable while video-only MP4 files are rebuilt and reuploaded. The `frames/` release remains available.
