    I’m doing a lot more 4K now with my Sony F5. But whenever I try to work with 4K 25P (and off-speed), the playback via SDI on the Decklink is terrible. It stutters and sometimes stops altogether. I’m using XAVC 4K clips scaled in a 1080 timeline. This feels like a hardware limitation. Is the RT downscaling too much for the Decklink?

    My system is;
    Adobe CC 2014
    Mac Pro 2012
    24gb RAM
    16gb SAS RAID-10 – 30% full
    GTX680 2gb
    Decklink Extreme 3D

    Does anyone else have 4K issues on 1080 Premiere timelines with their Decklink?
