Re-rendering in Sony Vegas

I have a Sony HSR-SR11 camcorder in HD HQ mode (1440 x 10800. I edit in Vegas 9 Studio Platinum.

When I import a clip, its properties are reported as:-

VIDEO AVC 1440 x 1080 x 12 Frame rate 25 (PAL) Upper field first
Pixel aspect 1.3333 (HDV 1080)
AUDIO Dolby AC-3 48,000Hz

I would like to be able to do some work on it and then render it TO THE SAME RENDERING FORMAT (ie. so that it does not re-render everything). Re-rendering a) takes a long time, and b) causes quality loss.

But I cannot find in Sony Vegas any render format the same as the video input from the Sony Camcorder - either as a template or custom. I've tried MPG HDV 1080-50i and Sony AVC AVCHD 1440x1080 PAL - all to no avail. It ALWAYS re-renders.

I asked myself, why would Sony not provide a template corresponding with the output from their own cameras? Am I missing something? Has anyone managed to render native Sony video without it being re-rendered?

Smart Render for AVCHD was only recently introduced in Vegas Professional 9, and they are still working out the kinks.

I do not know of any versions of Movie Studio that support this.

"I asked myself, why would Sony not provide a template corresponding with the output from their own cameras?"

What you're missing is that your camcorder came from Sony Consumer Electronics, and Vegas comes from Sony Pictures Digital. Despite the "Sony" in the names they're not the same company. There's no reason to expect any preferential support between the two products.

As you're discovering, Vegas Movie Studio doesn't support smart rendering.
