Vision SDI - Internal Loop/Input
This applies to all different OS versions and MXWendler 6.0 and above
Problem
You have a Datapath FX4 SDI, and a Datapath Vision SDI2 capture card and you try to use the outputs of the FX4 as input for your Vision SDI2 capture card. In MXWendler as well as Vision Fenster software, you realize the video flickers and has random timeouts.
Solution
Do no connect FX4 SDI outputs directly with Vision SDI2 capture card inputs. If you must make this connection necessarily, try to use a Scaler between the two devices.
