What means: DueToSourceFrameRate and how to fix this problem.

I use Blackmagic minirecorder 3 cards for inputs.
I try everything but nothing. Sometimes skip 1 frame but mostly many frames. This is happening since the start of record. Graphics card: GeForce GTX 770 with 4 GB memory.

vMix is powerful software but won't work correctly (for me) :(

When multicorder is stopped but all the cameras have been added to vMix, wait 5 minutes
and then take a screenshot of the Statistics window (click the colour bar button in the bottom right hand corner of vMix)

Hallo Martin,

At this moment i don't have connected cameras but add three decklink capture inputs to vMix (without video). Ok for this test?

I wait more then 10 minutes. Print screen:

Dropped just 1 frame.

After 1 h. 5 render droped frames and the same 1 source dropped frame.

When i change performance setings after 30 minutes print screen:

Hi,

The test results will need to be with cameras plugged in and sending video.
The blackmagic driver does different timing when nothing is plugged in.
