I'm comparing duplicate media files using MediaInfo, so that I can keep the one with the best quality and delete the other one. However, I'm confused by some of the information.

One Duplicate enter image description here Another Duplicate enter image description here

Of course Overall bit rate mode: Variable means that the bit rate varies throughout the file or playback.

But what does Overall bit rate mean? Is this the average?

If so, how can the Maximum Overall bit rate be lower than the average?

This issue is prevalent for many of my duplicate files and I'd really love to free up some storage space. Any help would be greatly appreciated.

Average bit rare of the whole file (all streams + container overhead)

If so, how can the Maximum Overall bit rate be lower than the average?

The maximum is a container metadata so ever the calculation of overall bit rate is wrong or the metadata is wrong.

so that I can keep the one with the best quality [...] I'd really love to free up some storage space.

Looks like you consider that keeping the file with highest bit rate is a good method for selecting by quality, this assumption is wrong. And for freeing space, it is best to choose the best quality/bitrate rather then highest quality at any bitrate (and no, this is not easy to do it automaticaly as the quality also depends on the source)

That was a bug in tsMuxer. Also as I understand that value is not real, as M2TS is Blu-ray specification, but SIT's peak_rate is not part of it, you just write maximum value allowed. It is not calculated, it is just a default https://github.com/justdan96/tsMuxer/commit/206fffcd4ce9dfa080d47ee6005e3620089f6b43
