Operation Manual

Appendix A: Setup options 255
Pre-filter: This option activates a smoothing algorithm
to improve apparent picture quality when capturing at
lower resolutions. The sharpness of the image is
slightly reduced.
Fast encode: This option speeds up the encoding
process with some reduction in quality when capturing
to an MPEG file. You may want to evaluate the effect
of this option in your production using a short test
capture.
Horizontal resolution: The Full option captures more
detail; the Half option creates every second horizontal
pixel by interpolation.
Crop: Activate this option to trim the edges from the
incoming video to eliminate “noise” that can occur at
the frame borders with some analog sources.
Vertical fields: A video frame consists of two
interleaved “fields”. The Both option specifies that both
fields should be captured; One uses only one of the
fields, reducing the vertical resolution by half. This
mode is useful when creating videos that will be played
back on a computer, since computer devices display
only one field in any case.
Audio settings
These audio capture settings are editable only if you are
using a Custom preset.
