Usable Video Format for Microsoft Support?

I swear the ineptitude of Microsoft support knows no bounds. You give us the option to upload a video, but the format for which the WINDOWS OS's SNIPPET TOOL USES AS WELL AS CIipChamp that is referenced as a program to edit with FROM THE SNIPPING TOOL (which this forum WOULDN'T even allow me to have as a word here...) uses MP4 BUT MP4 IS NOT ALLOWED...

I mean seriously who is in charge of this madness!? They should be ejected into the sun for this sort of stupidity, and then the tool tip gives you 0 information as well as the error. So freaking annoying and stupid.
