Try to get the camera a little bit closer and dont speed the clips that much up.
Also try recording with 60 fps because it lagged sometimes the sync was ok
Although alot of people are probably gonna get angry but as of terms of the actual replays i enjoyed 3 of them and in which i could actually compare those three to nuthug so great job on the replays but your camera was moving around too much and it was too fast too actually see what was happening... So so far id give it 5/10
