-# SparseVideoNav Privacy-Processed Videos
-
-This directory supplements the the `frames/bvn/` and `frames/ifn/` releases with episode-level MP4 files.
-
-- All videos are privacy processed for face and license-plate blurring.
-- All released MP4 files are H.264 at 256×256 resolution.
-- The prepared source collection mixes videos derived from privacy-processed raw recordings with fallback videos reconstructed from processed 256×256 RGB frames.
-- Per-video raw-versus-fallback provenance was not retained by the prepared source collection.
-- Two missing public episodes were reconstructed from their processed RGB frames while aligning this release.
-- Revisit episodes are intentionally excluded.
