# VidPhysOracle appearance-transfer videos

Layout: `<material>/<scenario>/<raw_sample_id>/<variant>.mp4`.
Materials use `rigid`, `soft`, and `liquid` (original `fluid` renamed).
Example: `rigid/dominoes/dominoes_0000/appearance_00.mp4`.
Named flag variants retain their original names, e.g. `black_disc.mp4`.

- `manifest.json`: one entry per Raw sample; transfer paths are relative to this folder. This is a transfer inventory, not a complete generation manifest: Raw reference paths and generation prompts must be supplied when combining with Raw data.
- `file_manifest.json`: original-to-new path mapping, byte sizes, and SHA-256 for every video.
- `verification.json`: counts and copy verification results.

All 6,272 official videos are independent copies, not symlinks or hard links. Source files remain unchanged in the sibling `transfer_6272` folder. Selection duplicates, download tools/logs, and other source auxiliary files remain there and are not part of this release tree.

When downloaded into `data/transfer/`, a combined dataset manifest rooted at `data/` must prefix these video paths with `transfer/` and associate each sample with its Raw reference directory. No Raw annotations are included here.
