There is a awesome "Export to Youtube" button at the end of a match... but it does't work o.ô
Huh, I have used it before and it used to work fine. But now I get this msg from Google. Anyway, all it does is turn a game into a ~10 second video, so the feature is (perhaps) not what you are looking for.

Is there to convert the match history into a video?
Yes, but you have to do it yourself (read: not really). What I did for some of my videos, is just turn on OBS, hit record and then hit play.
