hello,

is there a way to send out four inputs to four HD-SDI outputs on a Blackmagic Decklink card?
or only two and the rest to NDI only?

thank you for your feedback,
Dominik

So were you wanting to use all four SDI channels as outputs from vMix? Although a Duo 2 card can use all four channels as outputs, the limitation in vMix is for 2 external outputs in the 4K & Pro editions, and just one in Basic & HD. You potentially can have two "full screen" outputs (via the graphics card), which could externally be converted from HDMI to SDI, if that's of any help.

vMix can only output 2 signals to a physical device (SDI/HDMI/analog). vMix has two additional outputs (output 3 and 4) which can be used to for NDI purposes or etc.

vMix can output 4 physical outputs if you use external renderer.
For example:
I have a Helios 500 and use:
1xhdmi
1xDP
1xSDI (external rederer BlackMagic UltraStudio 4K)
