Re: Exporting problem/question

I concur. There are many reasons why not to do what you're trying to do. First, as Thad said, you will degrade the DV clip even if it's only imperceptibly these things get slowly compounded. Second, you are wasting precious productive time waiting for a render that was not needed. Third, manipulating all that material in AE is cumbersome so in addition to the wasted render time you spent time wrangling a very large clip.

The one thing of value I will add to this thread is the suggestion that you render your titles separately. Make each one the duration it will be on-screen in your finished show. Have no video behind it and render them QT, Compression Animation, RGB+Alpha, Millions+, Premultiplied. You’ll get a relatively small file with high quality.
