where to find video dataset ？

[dyyoungg]

In Huggingface dataset， I only see the video uuid in json files. How could I fetch those videos?
Thanks!

Hi, the dataset is based on Ego4D (https://ego4d-data.org/). Just sign the licenses (https://ego4ddataset.com/ego4d-license/), and they will send you the aws credentials. Then pip install awscli ego4d, fill in aws credentials via aws configure. Finally, follow https://ego4d-data.org/docs/CLI/ to download the videos ;)

Thank you for your careful reply！

Another question. The json file:

 "2d0c81c8-d7ff-4240-9ee7-4c71c152fb0a": {
        "8a889987-06aa-4778-bcd6-acd52bfe188f": [
            {
                "time": 0.8326981999999999,
                "text": "You pick up a jigsaw with your right hand."
            },

The ego4d.json file downloaded from aws：

 {
            "clip_uid": "7829e427-1b08-4226-a631-74e25b5d9e89",
            "video_uid": "2d0c81c8-d7ff-4240-9ee7-4c71c152fb0a",

                "video_base_denominator": 15360,
                "audio_start_pts": 0,
                "audio_duration_pts": 5209056,
                "audio_base_numerator": 1,
                "audio_base_denominator": 48000
            },
            "s3_path": "s3://ego4d-unict/public/v2/clips/7829e427-1b08-4226-a631-74e25b5d9e89.mp4",
            "manifold_path": null
        },

The first id "2d0c81c8-d7ff-4240-9ee7-4c71c152fb0a" is the video_uid, I found in the ego4d.json file, but i can't find where's the second id "8a889987-06aa-4778-bcd6-acd52bfe188f". What's the meaning of the second id?

Hello, the second id is clip_uid. Since livechat is generated by Ego4D goalstep, and that benchmark is proposed after Ego4D released, you may find that clip_uid in Ego4D goalstep annotations ;)
