Problem Exporting and Re-Importing 720p24

Hi everyone,
I've come across something I find strange. I have imported a p2 card worth of footage and assembled a timeline of the parts of it I want to keep. I exported as a Quicktime Movie using "current settings"- I'm assuming that would mean I would have no loss of quality or data. So anyway, then I re-opened that file in FCP and it was playing back jumpy. I discovered the problem was that the file needed to be rendered. But why is this? I can open that file in from Quicktime and it plays fine, but in FCP it needs to be rendered. Why would I need to render it if it is just exported (without any change in settings or compression). I'm working in a 720p24 timeline.
thanks for any help!

If you exported it using current settings then it should not change anything or add anymore compression. That being said if you are importing it back into a FCP timeline then you need to make sure your timeline has the same settings as the file.
 
oh. But aren't the files that go into my Capture Scratch QT? I figured that if I was taking a QT file and not changing any settings then it would be the same quality. So I guess it recompresses every time you export it. Is this an explanation why I'd need to render it once I brought the exported file back into my timeline? Is there any way to assemble clips on a timeline and export it in a way that doesn't further compress the footage?
thanks,

I posted the last post before I could read ozduc's post. So I guess I'm confused.
But yeah, I have the same timeline open with the exact same settings its always the 720p24 EasySetUp. I have the same project open and just open the exported QT file and drag it to my timeline and there's a red bar and says unrendered- the other clips in the timeline (the ones that comprised the exported QT that we are speaking of) still sitting there ready to play, never having to have been rendered. I've done it twice to make sure, one time exporting as "current settings" and one time exporting by selecting DVCPRO HD 720p24.
