No, rendering is for preview only and has nothing to do with exporting. If you do render for preview purposes, do NOT use preview files on export. It will usually degrade quality.

You can choose whether you want to use your preview files (means your allready rendert effects) or not. if you go to >edit>export>media, there you can switch on "use preview".
@Harm Millaard: I think this depense on the render setting. If you have the same resolution as your footage, you can use your render files to accelerate your output without degrading quality
If you limit yourself to DV, I agree, but not with any other codec. HDV, AVCHD, XDCAM, P2 and the rest suffer in quality when you use preview files.
I'm working with the matrox mxo2 le, and with this codec i can't see any differences. It's an MPEG-2 I-frame only with 50-300Mb/s. Can't you choose something like uncompressed, if you don't have a matrox installed?
Great Thanks for this, i used Canopus Eduis 5 to edit this footage from AVCHD to Canopus HQ. Then Exported the file to a Uncompressed AVI RGB File and Imported into Adobe Premiere CS5, Applied the Neat Video Filter, Setup it up and Now its ready for Export. But you have Said i Can Export Without Render and It shoul dbe fine. Which is Good. As Render would have taken 55Hours on my Intel i7 X980 CPU with 12GB Ram. Export will Take about 42Hours into a AVI File.
Thanks for you help if you think of anything else to sace time please message me.
