Question about the EgoQA split_N timestamp mapping
Hi, thank you for releasing VideoChat3-OL617K.
For Online_Supplement_Egoqa_mcq_hallucination_short_4091, the annotations reference media as <Ego4D video_uid>/split_<N>.mp4, and ol617k.json points to p2:s3://egoqa/split_videos/. We already have the complete Ego4D v2 full_scale videos, and all 697 referenced parent video UIDs are available. However, the annotation metadata provides only each split's duration, FPS, and frame count, not the absolute start/end timestamp (or frame range) of split_N in its parent video.
Could you please share the authoritative split-to-parent mapping, the script used to generate these files, or an official archive/source for the 4,091 split_N.mp4 clips? Also, could you confirm whether the directory name is the parent Ego4D video_uid?
Thank you!
你好，感谢发布 VideoChat3-OL617K。
对于 Online_Supplement_Egoqa_mcq_hallucination_short_4091，标注中的媒体路径为 <Ego4D video_uid>/split_<N>.mp4，而 ol617k.json 指向 p2:s3://egoqa/split_videos/。我们已经完整下载了 Ego4D v2 的 full_scale 视频，标注涉及的 697 个父视频 UID 也全部存在。但是，标注元数据只提供每个 split 的时长、FPS 和帧数，没有提供 split_N 在父视频中的绝对起止时间（或帧区间）。
请问能否提供权威的 split-to-parent 时间映射、生成这些文件的脚本，或者 4,091 个 split_N.mp4 的官方压缩包/下载来源？另外，也请确认目录名是否就是父 Ego4D 视频的 video_uid。
谢谢！
Thank you for your interest. I’ve been very busy lately and apologize for not responding sooner.
I think the most straightforward approach would be for me to upload the segmented videos (split_N.mp4), right?
I’m currently organizing the files and will update the Dataset Card once the upload is complete.
感谢你的关注，我最近太忙了，没有及时回复您，非常抱歉。
我想最直接的方法应该就是我上传一下这些划分后的视频 split_N.mp4 ？
我正在进行整理，上传完成后我会在Dataset card上进行更新说明。
