Q: Stuttering Ken Burns
I have searched and searched for someone who has had a similar problem and gotten an answer, but have not found it.
I created a series of projects, each 5-7 minutes long and exported each to a Quicktime movie, then imported them iback into iMovie to create a 1-hour video from the imported clips. The individual Quicktime movies play beautifully in Quicktime on my Mac. When I export the full movie to Media Browser at HD720, open iDVD and burn a DVD at Best Performance, the Ken Burns sections play back with a rhythmic stutter on both my Mac and my DVD player connected to the TV.
Since I know the individual QT movies are fine, the problem could be occurring 1) on the re-import to iMovie, 2) the export to Media Browser or 3) the encoding in iDVD.
Any wisdom is appreciated. It's been weeks since I finished the full project and I still can't get a watchable version.
Might the stuttering could be eliminated if I exported the whole movie to a Quicktime movie? I was trying to avoid that because it will take a full day to render.
iMac, Mac OS X (10.6.8), null

I'm not sure why you are getting the stuttering effect but if each of your short iMovie projects are complete you can join them together using Quicktime Player (see: How to use QuickTime Player - Apple Support
for more details). This avoids the quality loss that is likely if you re-import them into iMovie.
A DVD can only contain one hour of standard TV definition so iDVD may be having to do an extreme amount of compression on your 720p project. You may get better results exporting to 540p resolution.
