Hi
I have a problem that my fill and key of CasparCG is randomly async. It can happen at the beginning or after one hour. After another hour it can be in sync again.
I’m working with two Blackmagic DeckLink Mini Monitor 4K. Are the numbers maybe a problem? My config:
That is correct for the old Duo card, but not for the Duo 2. This has 4 outs and in the control panel applet you can set them up to 2 times fill and key.
The Duo 2 can only do HD. The 8K can also do 4K (I don’t know if it could do fill & key in 8K). So dependent on your jobs you can choose. If HD is ok, there is also the Duo 2 mini, that is a low profile card. You could also use the Extreme. It has a bunch of analog I/O, but it is more expensive and only a single fill & key.
In the end it is always better to have the fill & key coming from the hardware. Beside being more reliable you also gain performance, as Caspar only needs to output one stream of video instead of two.
