# SparseVideoNav Privacy-Processed Videos

This directory provides one privacy-processed MP4 for every released BVN and IFN episode.

- Most files are EgoBlur-processed versions of the original recordings and retain their original video resolution.
- When a matching readable original-resolution EgoBlur file is unavailable, the corresponding privacy-processed 256×256 RGB frames are encoded as the episode MP4 fallback.
- All videos have face and license-plate blurring. No unredacted raw footage is included.
- All published MP4 files are video-only; audio tracks are intentionally omitted.
- Revisit episodes are intentionally excluded.

## Layout

Each metadata row gives the instruction, video resolution, source type, and (for fallback files) the reason an original-resolution EgoBlur source was unavailable.
