Thank you Vivek! Thank you Andy! Thank you Stefan!
I did quite a bit of post processing in iMovie to brighten up the picture. I lost some color on the way, so I had to compensate for that by tinting the entire image. Still, the output of the web cam is pretty noisy, and there isn't a whole lot you can do about it. I agree that the audio is important, but it would be great if along with pleasing the ear I could please the eye.
I fed the bass into M-Audio's Ozonic audio interface and into Logic Pro. There I used Guitar Rig and Space Designer for processing. Then I bounced the track and did some post-processing in Peak. (YouTube overcompressed the audio quite a bit; I didn't know it would happen.)
Thank you! I'm actually a "faux" bass player. My main instrument is the guitar (you can see its 7-string headstock behind me in the video).
You're welcome, and I'm definitely planning to post more videos.
