I'm not sure if this may be a TMH bug (not had chance to triage it further as my dev wiki won't let me login), but it seems that when uploading new versions of a file, the prior version is shown in the file history.
I uploaded the originals and the replacements via importImages.php to commons
In the file history table, both rows show the same time, date, resolution and dimensions.
I know for a fact that they are different, and it can be confirmed by downloading the files
rev 1 is 155MB, rev 2 is 146MB. Similar can be seen on the other video.
It would seem that the Date/Time, dimensions and comment are using the wrong version. Thumbnails would look correct (see rotation on 747 video)
