Preroll Type a value in the box to specify the number of seconds of preroll Video Capture

When you click the Capture Clips button ( ) on the Clip Log tab, Video Capture will
seek to a point prior to your Timecode in setting determined by the number of
seconds you enter in the Preroll box. Video Capture will begin playback at the preroll
location, and switch to capture when it reaches the timecode you specified in the
Timecode in box.
Maximum RAM buffer size Drag the slider to allocate a portion of your system memory as a buffer. During
capture, this buffer is used to prevent dropped frames if your hard disk is unable to
write a frame.
MPEG video quality When capturing to compressed formats, you can drag the slider to adjust
performance. When you drag the slider to the left, you can increase performance by
decreasing video quality. When you drag the slider to the right, higher-quality video is
captured, and more processing power is required.
Note: Quality settings affect various types of material differently. With some
experimentation, you may find that certain types of scenes can be captured at lower
quality settings with little or no apparent loss of quality. Other material may need
the highest possible setting to achieve the desired quality level.
