On the Video tab, you can set the video resolution and quality. From the Resolution list, select Original if you want the resolution of the actual game to be preserved in the output video, or choose one of the preset sizes. Expand the Frame rate list and select a frame rate between 15 and 120 frames per second. The higher the frame rate, the larger the file size, so if your game is not an action-packed adventure, choose a lower frame rate – it’s the best way to save space on your hard drive.
Choose the output video quality by adjusting the Video quality slider. Note that high-quality game footage will take a lot of space on your PC, so make sure you have at least 2 or 3 GB of free space before recording.
You can also save the screen capture and webcam footage as separate files – just check the Capture separate streams box.
