I think we have provided the E4D_instructions.json
in our released onedrive folder.
As for the E4D.json
, it's around 300GB+ so we dont have a good way to release it with Onedrive. We may release it on HF later.
does the frames are extracted in one-frame-per-second?
Yes it's extracted with 1FPS from E4D videos.
If you downloaded the E4D dataset from the official release. You may see similar structures
ego4d_data/v2/full_scale/
Inside the folder there are plenty of videos. We extract them by 1FPS to store them with a key-value pair in a E4D.json
.
The key is E4D_IMG_{video_name}_{frame_number}
, for example E4D_IMG_01111831-9107-43c4-bf0e-6b26e9b32a2b_00000000
. The value is corresponding encoded base64 format image.
@pufanyi Fanyi has made it clear in https://github.com/Luodian/Otter/blob/6109be305f275e3aa3f1098b4078ab0d7e095aac/mimic-it/convert-it/datasets/fpv.py#L12
Please refer the code to convert your E4D.json. Since it's huge, so local processing may be more convenient.
thanks for quick responding, looking forward to E4D.json
if you may!
hi to the team, thanks for open-sourcing MIMIC-IT!
when i was inspecting MIMIC-IT Eggs, i noticed there is no Egg(that is, pre-extracted frames) for Ego4D instructions. Ego4D is a rather huge dataset that may takes 7 terabytes of storage and several days to download. so i'm wondering
thanks for your kind help!
