How do i watch my league of legends replays without using the the new Beta client

So I have the beta client and can watch the replay that I saved, but I would like to be able to view it through a 3rd party video source. This would allow me to save it indefinitely and send it to other people to watch. It's in something called a ROFL file if that helps. All this cuz I had my first double pentakill in one game. Any help would be appreciated! Thanks
