I'm using Final Cut Pro X in my nMP and have a question regarding to its performance. I use 1080p AVCHD video files and I know that the performance is less with that format, so thats the reason why I let FCP X convert them in Apple Pro Res. But I still have jerking/lagging and its not running smooth as I saw reviews on Youtube. I have also to say that the video files are on the integrated SSD in my nMP. Do you know what the reason for the poor performance could be?
