A fairly comprehensive tutorial about how to create a screencast-based video using CamStudio. Please click on "Show More" below to see important links and information.
This is a getting-started video on how to use the CamStudio free and open-source screen recording program, version 2.7. It covers video codecs and settings, audio setup, the 2 gigabyte file size limit, using Xvid, and much more crammed into 43 minutes.
Here are some more useful links:
NOTE: CamStudio is a 32-bit program and as such uses only 32-bit codecs!

Here is a text-rundown a viewer David shared of his steps for recording system audio:
I am running a Windows 7 Ultimate OS on a Gateway DX4300 64-bit desktop PC. My audio device is a built-in Realtek High Definition sound card.
What I did to configure the "mic and speakers at the same time" was ...
- In CamStudio V2.7, select the "Record audio from Microphone" setting set in the Options menu.
- In the Windows Sound Control Panel, select the Playback tab and select Speakers as your Default Device
- In the Speaker Properties, Levels tab, adjust levels of speakers and mic (start at 100 and adjust downward if, say, feedback problems occur)
- In the Speaker Properties, Advanced tab, select the sample rate (24 bit, 44100 Hz)
- In the Windows Sound Control Panel, select the Recording tab and select Stereo Mix as your Default Device, and FrontMic (e.g., for my configuration) as your Default Communications Device
- In the FrontMic Properties, Levels tab, adjust levels of mic to 100 and boost to +20.0 dB (again, adjust downward if feedback problems occur)
- In the FrontMic Properties, Advanced tab, select the sample rate (2 channel, 16 bit, 44100 Hz)
- (Optionally) In the FrontMic Properties, Listen tab, check the Listen to this device checkbox (unless if causes too much echo/feedback)
- In the Stereo Mix Properties, Listen tab, Playback through this device dropdown, select eother Default Playback Device, or Speakers (Realtek High Definition Audio, for my configuration)
- In the Stereo Mix Properties, Levels tab, adjust levels of Stereo Mix to 100
- In the Stereo Mix Properties, Advanced tab, select the sample rate (2 channel, 16 bit, 44100 Hz)
There you have it! Cheers!
