Increasing the frame rate 
If your system is unable to achieve an adequate frame 
rate (25 fps for PAL/SECAM, 29.97 fps for NTSC), try 
the following: 
Deactivate network driver and applications 
Network operations often cause interruptions during 
recording and playback. We recommend not working 
in a network. 
Audio recording 
Record audio only when you actually need it, because 
sound requires a great deal of processor time during 
video recording We recommend a PCI soundboard. 
Digital video with audio 
When recording digital video sequences with audio, 
remember that the audio also takes up hard drive space: 
• 
CD quality (44 kHz, 16-bit, stereo) requires about 
172 KB/sec.; 
• 
Stereo quality (22 kHz, 16-bit, stereo) about 86 
KB/sec., and 
• 
Mono quality (22 kHz, 8-bit, mono) still requires 22 
KB/sec. 
The better the sound quality, the more space is 
consumed. The highest quality (CD) is rarely required. 
However, the lowest quality (11 kHz/8-bit, mono) 
rarely provides acceptable audio sequences.
