So I'm really into youtube right now and I have a channel right now for just me with videos filmed with my iPhone. It actually works very well. The editing takes seconds for very awesome looking effects and everything. It takes a couple hours to take an idea of mine, film it, edit, then post it to Youtube. I have been working on a script for a year or two now on a (Machinima) if you don't know what that is then go to www.roosterteeth.com and find Red Vs Blue. My story is not a copy of that in any way, the ideas are very different and unrelated but i don't know how to film it. I heard something about a capture card? Some editing software? Something. But I really just want to find the best, cheapest, easiest way to record videos like that. Including the In-game audio. Doesn't have to include our voices. I have iMovie for that to add both audio and video together. So i have a computer, an iPhone, a Tv, an X-box360, and one headset and some friends that have the same. What do i have to buy? What is the simplest why?
