Repeated RGB frames #26

Closed VitorGuizilini-TRI closed 12 months ago

VitorGuizilini-TRI commented 12 months ago

I downloaded the RGB frames of a few sequences, and it seems like they are duplicated. For example, P01_01/frame_0000000437.jpg is identical to P01_01/frame_frame_0000000438.jpg, then P01_01/frame_0000000439.jpg is identical to P01_01/frame_0000000440.jpg, and so forth. Is that expected? If yes, what is the reasoning behind that?
My main goal is to align this data with the EpicFields poses, so any help is highly appreciated. Thank you!

In videos collected in 2018 using GoPro5 (you can identify these videos by PXX_YY instead of PXX_YYY for later recordings), the camera setting in low light results in duplicate frames - this is an issue with the camera itself. This explains the phenomena you noted above and we have this noted in our README.

The frames in EPIC Fields are already aligned and you can visualise these using the code here: https://github.com/epic-kitchens/epic-Fields-code
