So I was tooling around with FCP X for the first time yesterday, and in the midst of doing that I told iTunes to perform a massive HD-intensive task, and oh by the way, Time Machine decided to jump in and ruin my day even more. FCP slowed to a crawl and little yellow triangle icons with exclamation marks started appearing over my events (I could not find a way to get it to give me a specific error). I was doing some speeding up and slowing down of video and lo and behold I think I have some dropped frames in the finished product. Not a big deal, I was making a stupid youtube video that nobody (including myself) will watch. I'm going to try and fix it today, but just in general: Obviously FCP X will slow down in the event of low HD throughput, but will it actually screw up?
