| # MEDit-Bench: Temporal Grounding Annotations | |
| Human-annotated temporal grounding data for 60 YouTube videos. For each video, | |
| annotators were given a short list of "summary messages" describing the video | |
| and asked to mark every time range in the video that supports each message. | |
| Each message was annotated independently by 3 annotators. | |
| This dataset ships **annotations only** — no video files. Each row points to | |
| the source video via its YouTube ID / URL so the underlying footage can be | |
| retrieved directly from YouTube. | |
| ## Dataset structure | |
| One row = one summary message annotated by one annotator. | |
| | column | type | description | | |
| |---|---|---| | |
| | `video_id` | string | YouTube video ID | | |
| | `message` | string | Summary message text (English) | | |
| | `annotator_index` | int | Index (0-based) of the annotator — 3 annotators per message | | |
| | `segments` | list of `[start, end]` | The cuts this annotator marked as supporting the message. `HH:MM:SS:FF` timecode (frame number — not converted to seconds since source frame rate varies). | | |
| - 60 videos, 180 messages (3 per video), 540 rows (3 annotators per message). | |
| ## License | |
| Annotations are released under CC BY-NC-SA 4.0. Source videos remain the | |
| property of their original YouTube creators and are not redistributed here. | |
