XNVIEW for Pictures vs Videos

Is there a difference between the data that needs to be changed for reusing/Reposting a Picture vs a Video for Instagram?

So far I’m Renaming the file and using Xnview for Removing all metadata but wondering if theres a difference between how IG sees metadata in a picture vs a Video?

Also I saw in the search that some recommend changing MD5 hash but is it better to just use the software itself version when posting?
