A large quantity of the matches are quite laggy, it's not your computers issue, but mine. However, if you are using this video for "scientific data", I did count each frame for the moment the final blow was dealt. The export frame rate may not matter too much, as it would most likely only change the timer by 100ths of a second I believe.
The only things you can currently do in the game is make no factions at all, basically a free-for-all, and another setting called all hostile, that does the same thing apparently. I haven't found any differences. I used spectator mode so they wouldn't attack me, and the aforementioned no factions setting. There is currently no way to make certain enemies fight others. Say a Flame Trooper and Skungus, versus a Stormtrooper and a Mykal.
