There's plenty more, but honestly if an LMGTFY link like this can answer your question it sounds like you're actively trying to keep yourself from finding out what's going on. There are no conspiracies here, it's just tech, it works, it's very cool, and there are even fully functional simulators/emulators allowing you to code without access to the devices. It's a shame you're so sure there's something wrong that you're preventing yourself from getting involved with something that clearly interests you.
[edit] I see now you said you wanted a video "from microsoft" - that's in the very first video hit searching for hololens capture[0]. This video has other stuff in it as well, including discussion of an open source hardware and software system for making hololens captures, but there is absolutely straight hololens capture video in the link, just like in the other link I sent. Again, it feels like you're trying hard to not let yourself find or see this stuff.

The reason I asked for video from Microsoft is because users consistently crop the views to only show the postage stamp AR view HoloLens offers and presents it as the full video which is a misrepresentation of what HoloLens is capable of. Also, that second video doesn't actually include any video from the HoloLens from a wearer's perspective but thanks for trying.
I don't want to interact with you anymore.
45 seconds into the clip on the verge site are four separate captures shot by the HoloLens showing the wearer's perspective, and the other clip is 100% user POV shot by the HoloLens. The verge clip is produced by Microsoft, the other clip by a user. Neither the user nor Microsoft cropped the HoloLens footage, both clips were shot with the integrated HoloLens camera which is tuned to match the active field of view of the headset. The rest of the verge clip shows how to build an open source capture device capable of recording a wider field of view at higher capture camera resolution and shows video shot using that system with a DSLR and a HoloLens. There is no "misrepresentation of what HoloLens is capable of" in either of those videos.
It's not vaporware, though you may not be able to find the exact videos you personally are looking for. Maybe that means it's just not for you. No bigs.
