1:1 Frame Rate

Disabled
Enabled
The 1:1 Frame Rate feature is useful when you need to display video from both 60Hz and
50Hz sources, as long as your video display can operate at both frame rates. Some video
sources, such as Blu-ray players, can output 24Hz video. If you have a 24Hz source and
your display can also accept 24Hz, enabling 1:1 Frame Rate will allow the 24Hz video to pass
through the iScan Duo from source to display.

Frame Lock

Auto Lock The output frame rate from the iScan Duo is fixed and locks to the input
Unlock
Frame Lock provides more options for handling input and output frame rate and timing variations.
In some cases, this feature may provide smoother operation when switching input sources
or formats.
•

Aspect Ratio

Aspect Ratio sets the display aspect ratio. If you have an HDMI display, Auto (default) is
the safe choice.

Color Space

Color Space provides four choices for output color space. If you are unsure what to use,
Auto (default) is the safe choice.

RGB
YCbCr 4:4:4 Component color space used for video standards; 8 bits per component.
YCbCr 4:2:2 Component color space used for video standards: 10 bits per component.

Colorimetry

Colorimetry refers to the standards by which RGB is converted to YCbCr. There are two stan-
dards for performing this conversion:
ITU BT .601: This is the colorimetry standard for Standard Definition video formats.
ITU BT .709: This is the colorimetry standard for High Definition video formats.

The output frame rate from the iScan Duo is fixed.
The output frame rate from the iScan Duo tracks the input frame rate.
This avoids performing frame rate conversion, which can result in stuttering
motion in some cases.
