Sorry for the massive the latency guys. University is a cruel pain in the ass.
Thanks for the responses btw. They're really helping. I've been going through them.
Well, here's what's required for now:
The video must be be 10min long
If we omit something around 20sec for credits scene and about 10sec for the intro;
it'll leave us with 9.5min.
Let's say a good single player replay would be about 15sec long and give 25sec for a multiplayer.
If I get 10 multiplayer replays and add stuffs like transitions, effects, slowmotions &..., I'll manage to make something around 5min of the whole video.
4.5min will be remaining.
16 single replays will do the trick.
To conclude, 10 multiplayer (25sec) and 16 single-player (15sec) replays will do the trick.
I want you to start with the best and the longest multiplayer replays you can find.
