Good work with the videos.
I used to make tutorial videos of Emacs but stopped due to lack of
time. I have a few suggestions that might help you get more mileage out
of low cost equipment.
1. If you make the whole thing into a screencast rather than a video
(via a webcam), you won't need the camera and you have a way to show
slides/notes or something else that can support your presentation. This
will be especially valuable during sessions where you're showing code.
2. It looks like you're recording using your laptop microphone. You
can get much better audio quality if you use a cheap headset with a
microphone close to your mouth. Your own voice will be much higher and
the background noise will be much lower. I think the one I used was just
a few hundred Rupees and was the kid of single ear thing that tech
support people are often seen wielding.
3. There's a hum in the background (I'm guessing it's a fan). It's
very uniform and you can easily clean this up using audacity or some
other free tool.
Here's an example of one of the Emacs screencasts that I made
http://archive.org/embed/EmacsMovies/12.3-episode-gnus-3.webm. The noise
clearing was done manually using audacity but the rest of the workflow
(boosting audio, adding mezzanine clips, transcoding to multiple formats
and uploading) is automated using ffmpeg and other tools. The details
are there in this Makefile https://gist.github.com/nibrahim/2466292. One
of the early posts on the website discusses the workflow too
