Hello - I need some help understanding something. I’m looking at two WEB-DL files from reputable groups that are identical in nearly all ways (see info below), except one file is noticeably larger than the other (2.8GB vs 3.47GB, for example). I thought WEB-DL’s should be the same size if they’re from the same source (AMZN in this instance), so I’m a little confused as to why there’s such a disparity in size when all else appears equal.

Any idea’s what could explain the difference in file size here? I’m assuming the FLUX file is older based on when it was first uploaded vs the NTb one. Could this have something to do with it?

Bonus question: Which file would you choose in this situation?
