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).
