How We Record Videos Pt. 2

Hey everyone!  Zeldafan314 here to discuss the technical side of things.  Just a warning: this is a pretty complex setup.  If you don’t understand you can ask a question in the comments. This setup only works for macs but I can probably link you to some PC alternatives.

So if you’re just going to record this (not streaming) then it’s simple.  Just go to the Elgato video capture application and hit record.  If you’re streaming it, open the Elgato program and get to the final screen but don’t hit record.    Now you need to open camtwist.  This is where you mix all your video sources.  What you do in this next part depends on what you want your stream to look like.  If you want just the game,  double click “desktop+” and select “Elgato A/V input”.  If you want just to be part of the stream, select “desktop+” then hit “PIP”.  Then you can select it, move it and resize it.   Then you can add other video sources such as a webcam as you please.  Now you have to actually stream this.  You can do this either at or using their application Ustream Producer. I recommend the Producer option since it uses less processing and it makes your stream viewable on the iphone and ipod touch (although the app is crummy).  Technically you could do all the mixing from producer but it’s highly inconvenient, I recommend camtwist.   Now in producer, select camtwist as the video source.  If you hit broadcast it’ll seem like it all works fine, except for audio!

Audio is the real killer, it took me forever to figure this out. So first of all you’ll need soundflower.  This is basically a virtual audio mixer.  So what you do now is you set the audio output from the computer to go to soundflower (16ch). You can do this through system prefs –> sound.  Since the game audio is being outputted to your speakers via Elgato this captures it. But as a byproduct this also captures any audio coming from your computer.  So be sure to mute your AIM,Mail etc. sounds.  Now if you go into producer and set the live audio to soundflower (16ch) you will now be broadcasting game audio.  Now to route your voice.  You could just select the audio input to be mic but then you wouldn’t hear the game.  So you need to output it through your “speakers” which is actually going to soundflower.  This can be accomplished through Garageband.  To do this open garage band and add a live instrument.   Set the input to the desired mic.  Then turn your feedback on so it outputs to soundflower.  So now everything should be working!  You probably want to hit the headphone button in producer to get rid of any possible echo. If you want to use multiple mics, open audio midi settings and create a new group then select it in garageband.

This setup using a lot of processing  power, like any would.  If your computer is slow, the stream will be a little laggy, like ours was.  Again if you have any questions please comment!
