How to Submit Video of Cheat/Glitch in Map

I was playing BTB earlier and I noticed that I was getting shot from above the map. As I panned my camera, I noticed that someone had gotten on top of the BTB map Scavenger. I want to share the video with 343 so that the issue can get fixed. Thanks!

There is a report a matchmaking bug thread over in matchmaking feedback and discussion; they give instructions on what information they need in the first post in that thread.
