Export previews without rerendering (AHD, PP CS3)
 

I hit space to preview a timeline in PPro CS3 with Aspect HD. Now i'd like to export the previewed timeline to cineform avi without rendering the whole timeline again. Is it possible? I tried exporting with recompress checkbox unchecked but with no success, everything has to render again.

The timeline has many layers, effects and AfterEffects Dynamic LInk comps, it would spare me lots of time. I know it's possible to drag the clips from preview folder, but there are hundreds of them.
