4K2HD Mini-Converter v1.15r1 16 www.aja.com
Output Mode
4K Convert
• Downconvert - Downconverts incoming 4K signal to HD (default setting).
• Center Cut - Selects the center portion of the incoming 4K signal for display.
No down-scaling occurs, and the output format is either 1920x1080 or
2048x1080 (depending the input source and the 2K Crop setting.
2K Crop
Choose On or Off. Provides the option of center cutting 2Kx1080 video signals to
make 1920x1080, or center cutting a 4Kx2160 signal to make 1920x1080. Default
is On.
Edge Filtering
Choose On or Off. You can disable edge filtering with this control. This is useful
if you are stitching together multiple images of 4K2HD outputs. An example is
using four 4K2HD’s to view UHD-2 or 8K on a UltraHD/4K or HD monitor. Each
4K2HD downconverts one quarter of the 8K image. Disabling edge filtering can
eliminate the center vertical and horizontal lines that would occur between the
quadrants in that situation. Default setting is On.
SDI Out
Passthrough
Choose Auto, Off, or On (default is Auto). This setting can be used with HD or 2K
psf format input signals. When On, psf format will passthrough to the SDI output
instead of the converted, progressive format signal.
3Gb Mode
Choose Auto, 3G-A, or 3G-B (default is Auto).
Progressive to Interlace Enable
Progressive to Interlace Enable. Choose Off or On. When On, a 4K/UHD
progressive input will be output as a 1920x1080 interlace signal when possible.
More specifically, when Progressive to Interlace is enabled, the 4K2HD converts
4096x2160 or 3840x2160 progressive signals to a 1920x1080 interlace signal. Crop
is automatically applied if the input signal is 4K.
This conversion is functional for the 4K and UHD input formats listed below:
