• Dedicate a separate hard drive for your video captures, or a separate
partition on an existing hard drive.
• Capture at the best quality possible and then resample down if
necessary. Resampling up creates (interpolates) new data which results
in lower quality than the original.
Apart from controlling how your system performs, you can also set up
Video Capture to optimize your captures using the Advanced tab of the
Capture Video dialog box. Here you will find several options dedicated to
enhancing capture performance, such as allocating additional memory
buffers, specifying chunk granularity (data pack size), freeing up RAM
and synchronizing video to audio.
For more video capturing tips, please refer to the appendix (see page 403).
Techniques for improving your audio captures
When capturing audio there are three areas that you can control which
determine the size and quality of the audio file. They are the sampling rate,
sample size, and the number of channels. CD quality audio has a sampling
rate of 44KHz, a 16-bit sample size, and two channels (or stereo). If you
intend to play back your video over low quality speakers, then capturing at
this level is not necessary. You may find a mono, 11KHz 8-bit file more
practical. Also, if you are capturing background music, then it may not be
necessary to capture it at the same time you are capturing the video – you
can always add it later as an audio track in Video Editor. (For speech, this
is possible but it will require more effort later in Video Editor to
synchronize the audio with the video.)
Capturing videos and images
Once you have set up the video window to display your desired video or
image, you are ready to capture. Before doing so, it is suggested that you
