Extremely different picture result from 2 broadcasting cameras

[ThorAdam]

Currently streaming a DJ Set with 2 cameras: Sony PXW-Z150 (XDCAM / XAVC) and Sony FX1(HDV). FX1 is fine, but the Z150 (connected via WiFi) keeps producing problems.

On iMac (27“, 8-Core i7). Let me know what other settings you might need to know to help me with that.

thanks a lot.
