Sparring video : Thanks to add me. You should use freecam to record your replays. Pause the game when there is a strong hit, for exemple, hit 2 and move the camera where you see well the hit, press K. unpause the game and continue like that until the end of the replay. Now, when you watch it, the camera move alone to the K points with a kind of fluidity.

Some options should help you too :

/opt blood 0 and /opt boodstains 0 for non-fight replays (like soccer)

Continue your good work ;)
