In your situation, you’re transferring video from one app to another for further rendering. You want an intermediate, low-compression (actually lossless) high-quality codec. Use Quicktime’s Animation codec at 100%.
Remember, this is not a delivery codec, so it will not play back smoothly on your computer because its compression is so low, and as a result, its data rate is so high. At the end of the project, choose a delivery codec so you can play back the file for your chosen final medium. That could be Sorenson or Windows Media 9 for the web, DV for tape, or a broadcast codec that your editor uses for eventual broadcast (Avid, media 100, Blackmagic, etc.).
Hope that helps,
