I’m no video engineer, it just worked where v30 and v60 cards did not…that’s all I’m saying here. I hope yours work great for you.V90 is overkill for 2k video on the controller, even for the 100MBps 4k on the drone; - but had they been available I probably would have purchased them. The V30 cards I have do 200MBps read, 160MBps write.
