Video quality depends on the computer speed and the recorded video size. Dual core computers, 2 GHz+ are the best choice. To get the best quality video – especially on slower machines – try the following:
Go to Settings, and make sure you are using the MPEG-2 video format. You can also try one of the Recommended Settings options for slower PC’s.
Try recording from a smaller video window by resizing your video player to 1/4 of your screen, or no more than 720×480 pixels. You can select a lower zoom level for your browser. This won’t affect the video quality (since video is scaled UP from smaller sizes to fit a full-screen picture). This will require less computer power to capture, which will make for smoother videos.
Use Windows “Best performance” mode instead of “Best appearance” on Vista/Win7 computers. You can open Windows Performance Settings from WM Capture (click Settings/Tool/Windows best performance) or simply switch Windows theme from Aero to Windows 7 Basic (right click the desktop then click Personalize).
