System information
Item Description
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.
When performing compressed capture to MXF format, increasing the
buffer size can help prevent dropped frames when encoding complex
frames.
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.
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.
