Capturing audio along with video puts a greater
strain on your PC than capturing video alone. If your
PC drops many frames while capturing audio and
video together, then capture the audio separately with
the audio capture utility from Windows. The audio can be merged
with video later on during the video edit stage.
Suggestions on capturing video
Captured image sizes can be either 160x120 or 320x240 pixels.
For the best trade off between image size and captured frames per second, use
a 320 x 240 image. With a 166MHz processor MMX (or better) and a reasonably
fast hard disk drive, you should be able to capture 30 frames per second using
the YUY2 OR RGB format.
The consumption of hard disk space is dependent upon the size of the video
image while capturing, the image format plus the number of frames/second.
Using the YUY2 OR RGB image format, the following chart shows hard disk
space consumed:
