Hi,
I have a pixel offset when using the two SDI outputs as Key & Fill, and I hope you can help me fix it.
EQUIPMENT:
Resolume Arena > UltraStudio HD MINI > 2x MicroConverter BiDirectional 3G > ATEM Mini Extreme ISO
Computer: MacBook Pro 2019 16" running macOS 10.15.7 Catalina
APPROACH:
I am playing video with Alpha Channel (QT ProRes 4:4:4:4)
In Advanced Output I select the UltraStudio as an output with the correct resolution (1080p50)
Color Range, Color Space and Alpha Type do not alter my results
I convert both SDI signals to HDMI and go into two inputs of the ATEM
In ATEM Software Control I setup the Downstream Key 1 with Pre Multiplied Key and no mask
As a background I set a orange color
EXPECTED BEHAVIOUR:
A perfect key
OBSERVED BEHAVIOUR:
Key and Fill seem to be offset by a couple of pixels horizontally. Threre doesn't seem to be a time offset. When I change some settings in Resolume (Keyer External vs. Internal) the offset shifts, but it's never perfect.
Some images here, the last one is a reference (how it's supposed to look like):
