Each JSONL row corresponds to exactly one image and one English caption. ## Layout - `data/annotations.jsonl`: release records, one per extracted frame. - `data/annotations.json`: the same keep-only records as a standard JSON array. - `data/manifest.json`: release counts, source policy, and timestamp convention. - `images/`: JPEG frames named by `annotation_id`. - `source-videos/README.md` and `source-videos/manifest.jsonl`: canonical source-video policy and grouped source links. Complete MP4s remain in `Xinyun-Liu/WorldModelBench` and are not duplicated here. ## Timestamp Convention One- and two-digit timestamps are seconds. Three- and four-digit timestamps use the final two digits as seconds and the leading digits as minutes. For example, `515` is 5:15 (315 seconds), and `0158` is 1:58 (118 seconds). `timestamp_raw` preserves the submitted value and `timestamp_seconds` contains the decoded extraction time. ## Provenance Every record contains the original WorldModelBench file path and public URL. Use `text_caption` as the English instruction. The release does not duplicate source MP4 files, so the source dataset's terms and provenance remain attached to the original video assets.
