Training dataset requirements

[EvdoTheo]

Hello everyone, I'm trying to understand the purpose of each folder/file in the training dataset in order to create a custom one with Blender.
I see 4 folders :

1. color
2. intrin_ba
3. poses_ba
4. repoj_box
5. A video file
6. and a text file "intrinsics.txt".

I get that the intrinsics.txt file has the camera parameters, but in the intrinc_ba folder what kind of parameters are included for each frame? I comprehend that the intrinsics do not change, but only when the focal length is modified. So, the first question is about the meaning of the parameters inside the intrin_ba folder.

My second question is why the frames inside the color folder have smaller (512x512) dimensions than the original video file (1920x1440) and if this condition affects the reprojection's box results.

If there is anyone with the knowledge to create a custom dataset, it would be very kind of him/her to provide me with information about it. Thank you.
