Modifying the Config File Manually

You can also modify the configuration files manually to change the framerate and resolutions. To do this, follow these instructions:

For Windows,

    Make sure Skype is not running.
    Open the config.xml file located in the Skype user profile directory, usually in %APPDATA%\Skype\yourskypename\. If you are not sure where this is, copy 
and paste %APPDATA%\Skype into Windows Explorer to find this directory and then find the folder labeled with your Skype username.
    Add the following code somewhere in the config file:

    <CaptureHeight>480</CaptureHeight>
    <CaptureWidth>640</CaptureWidth>
    <Fps>30</Fps>

    You can modify the parameters as you see fit, though I recommend trying these first.
    Save and close the modified config.xml file.
    Start Skype and enjoy high quality video!
