36 Studio 8
To capture at full quality, your hard drive must be
capable of sustained reading and writing at 4 MB/s. All
SCSI and most UDMA drives are capable of this. The
first time you capture at full quality, Studio will test
your drive to make sure it is fast enough.
MPEG
DVD and S-VCD discs both use files in MPEG-2
format, an extension of the MPEG-1 format used for
VCDs. MPEGs intended for use on the Internet will be
at lower resolutions and in MPEG-1 format.
The Capture format panel (Setup > Capture Format)
includes a variety of options to control the quality of
MPEG captures.
Another option lets you adapt the way MPEG encoding
is carried out to the speed of your computer.
• The first option, Use default encoding mode, leaves
it up to Studio to decide which of the other options to
apply, based on its estimate of what is likely to work
well on your machine.
• The best choice for very fast machines is Encode in
real time, in which capture and encoding are carried
out simultaneously.
• Finally, slow machines will use the fallback mode,
Encode after capturing, which obviously takes
longest but ensures that capture will be as near to
error-free as possible.
Refer to “Capture format settings” on page 165 for
detailed information about MPEG quality options.
Audio and video levels
With DV and MicroMV captures, you are using audio
and video that have been encoded in the DV file format
