MediaInfo's 'Overall bit rate' vs 'Maximum Overall bit rate'
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
Another Duplicate
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.

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

I'm not sure what you mean by 'container metadatam so ever the calculation of overall bit rate is wrong or the metadata is wrong'?? notably, i'm not looking to save space, i'm looking to free up space by deleting duplicates. bit rate is just one of a few other factors like frame rate that i also use to select the best quality.

im not sure which bit rate is the correct to use? overall or what about nominal bit rate which is sometimes listed under the video section? what does nominal bit rate refer to?

@user2230470 See also: superuser.com/questions/338725/… — you cannot just compare based on bitrate/framerate alone, even with the same content.

"nominal bit rate" is a bit rate indicated in metadata (in your case video bitstream metadata)
– Jérôme Martinez
Feb 18 at 16:45
@slhck more often than not the duplicate videos im comparing are identical in all other regards, except these particular bit rate values. thanks for the link to your other comment nonetheless. lots of valuable info
