YAML Metadata Warning:empty or missing yaml metadata in repo card

OCR
The primary artifact is ocr.jsonl còn artifact_metadata.jsonl records the input, model, prompt version, subset, and Git lineage
ocr.jsonl
Each line is one OCRFragment, a visible text region in one keyframe.
Common fields:
fragment_id: OCR observation identifiervideo_id: source video identifiertime_span:[timestamp_ms, timestamp_ms]in source video timetext: recognized visible textbbox: normalized text region withx_min,y_min,x_max, andy_max
There is no placeholder for frames without text and no fabricated confidence score. Join OCR with captions or detections on video_id and timestamp; compare normalized bounding boxes when spatial context is needed.
Generation flow
HunyuanOCR reads the canonical keyframe images, emits visible text regions, and the job validates each result as an OCRFragment. It publishes one flat JSONL file and removes provider work files and the retired bundled OCR representation after a successful run.
Run OCR for the original keyframe set:
make data-ocr INPUT=/data/aic/shared/artifacts/keyframes/keyframes.jsonl OUTPUT=/data/aic/shared/artifacts/ocr SUBSET=700vid
