What's the best export format for Keynote to iMovie?

Question

Okay, here is the situation, I have a lengthy Keynote presentation which I plan to export via QuickTime so it can be imported in to iMovie in order to do voice-overs. The question I have is what the best format is to use to export from Keynote in order to import in to iMovie. I am obviously looking for the format which is the smoothest, doesn't lose any quality, and will look clear once imported in to iMovie. Also, there is no reason to use H.264 since size during the transfer doesn't really matter to me, besides, H.264 seems to be somewhat jerky with Keynote exports (or maybe it's just my computer) as I am using some of the graphics intensive transitions and effects.
Also, I know that when you send movies directly from Keynote to iDVD or from iMovie to iDVD, it uses a format which is directly compatible and there is no conversion that takes place, is there a format which will work this way from Keynote to iMovie or does it always have to do the conversion.
Finally, the other thing you should know is that I created the presentation in Keynote using 1280x720 in order to achieve the true widescreen aspect ratio. Now, I am NOT looking to keep this in HD, once I import it in to iMovie, I only need the standard DV Widescreen resolution since I will eventually transfer it to iDVD to burn it as a widescreen DVD. So, I would also appreciate some sort of input as to whether I should export the QuickTime file out of Keynote as the full 1280x720 and then let iMovie do the down-sampling, or should I export it directly out of Keynote using the standard definition widescreen resolution? Please, I would appreciate ANY help on this!!!

Hi Cornelius,
this is the workflow I had which worked fine for me:
My situation was that I had two existing movies in different formats, which a had to filet, add keynote foiles at the beginning (like "Confidemus presents" and so on), between chapters and at the end.
The best way to stick all this together was indeed to export to Qicktime and there to choose the highest resolution. There are several options. The most important point was to have all transitions within foils in keynote approprately defined, because after export it is not possible to do something in iMovie with it.
After having edited the movie in iMovie (that means adding transitions), next I will use Garageband to add sound. So you see that is the point where I'm standing at the moment. I have one time edited sound with iMovie, but Garageband seems to be more sufficient to do that. I have done a little radio play together with my daughter with Garageband and I found it very nice and - of course - easy to use. There are more effects in it and when you are familiar with this editing scheme in Garageband you will love it.
All the best
