Alpha Client Replays...I need help

Today I played Draven. As I don't normally play Draven I did not expect to need any of my game recording software running. However, something happened...I got a pentakill.

The game is viewable from the client match history as it is supposed to be, but I would like to be able to upload portions of it to YouTube or email it to someone for inclusion in montage/top-plays etc.

The easiest solution I can think of for this is to simply record my screen with OBS or Fraps or the like while viewing the replay, but I am curios to know if there is any way to access the file itself for the replay inside my files.

Thanks in advance for any help in this matter! The game in question is linked and is here.
