Hey guys, I am in the process of putting together a few videos. Here's some background which may assist. If you do not feel like reading it, that's fine, simply skip to the bolded heading of "AND HERE IS THE PROBLEM" The videos are essentially going to be one person talking on a green screen background. No fancy camera angles, not even zooms or anything. Just one person talking for about a minute and a half. I have a Sony HDR-CX110 HD video camera. It produces fantastic video quality (pretty much blu-ray quality outdoors or indoors with proper lighting). The problem is the audio. It only has a built-in stereo mic, which isn't bad for home movies and such, but is terrible for more "professional" applications. Now, I do have a lavaliere mic (audio-technica ATR3350). Unfortunately, the camera being a consumer-grade HD camera does not have a mic input. The only camera I found with one is the Kodak Zi8 which has terrible video quality (3 out of 10 IMO) compared to the Sony (9 out of 10). So what I have decided to do is hook up the mic directly to my iMac (Aluminum 2007 Model, using iMic from Griffin as the input as there is no mic jack on this iMac that I am aware of) and record the audio using Garageband. This is made possible by the 20 foot cord of the microphone. Then I plan to edit the movie in iMovie (basically, use the green screen to give me the desired backgrounds throughout the clip). Once this is done, I will import the movie into GarageBand, where I plan to mute the audio from the video source, and simply play the audio I recorded directly into Garageband during the shoot. I have tested this with a few sample clips I recorded and I have been able to synch the lips up to the separately recorded audio perfectly. Now that you have the complete background.... AND HERE IS THE PROBLEM The problem is that the audio recorded directly into GarageBand with the Audio-Technica mic has a bit of a hiss. I have tried playing with some of the effects and it seems like some of them mute the hiss a bit, but none eliminate it. My question is, what can I do to eliminate the hiss? I had an M-Audio microphone that cost around a $100 which did not produce the hiss IIRC. It is mostly audible if I turn up my iMac's speakers halfway up or higher. Does GarageBand have some sort of filers or settings that get rid of it? Is this something that will always occur on a mic that uses an analog input? (The M-Audio was a USB mic)? Am I just being a perfectionist and this kind of hiss is normal when you turn the speakers up on any video? Thanks!
