Have you ever watched a video online or something of a person playing a game on their computer/console and the video is a direct "as they would see" feed instead of some stupid camera in front of the TV? I wanted to know how that is done.
It isn't hard! The difficulty recording from a video game console to a computer is the lag time which can make the video game unplayable. In a very sensitive game, a mis-timed shot or jump could make the whole thing not worth recording. With the right hardware and computer/software combination, things will work just fine.
Recording from the computer is easier but there is some difficulty when it comes to sound. Many programs want to record sound from the microphone as if I am directing you through my computer as in a video demonstration. That's great but I want to record the audio coming out of my computer and use that with the video.
Logically, you could take a male-male head phone jack from the headphone port to the microphone port. It doesn't work very well (too much feedback) but that is the concept. I found a great program called Virtual Audio Cable which allows you to do just that. I found this program to be a bit complicated at first but I don't understand computer audio and video very well.
Most computers have real sound cards and laptops have good virtual sound card drivers. Good hardware and drivers will provide this functionality. I have a great laptop but the sound system (one speaker) sucks and the drivers are sub-par. There are ways to mix audio in Windows alone with no other software required but if you're in the same boat as I with cheap sound drivers, this might be the way to go.
I was able to re route the audio out which would normally go to the speakers back in as the microphone. I disabled the actual microphone. I then took that audio out and routed it to the speakers. As a result, you can see what I'm doing and hear the noises that the computer makes without hearing me sneeze. You can see my results in this youtube video of a bootleg Super Mario game.
Eric, you do this stuff. What do you use?
