"smart rendering" with V8

I've been trying out the so called smart rendering using a SD mpeg2, without any changes (just as it is).
Been very careful to select the "render as" as identical to the original. It doesn't seem to work, thought just be a matter of basically transferring a file from one location to another on the pc, but no, it seems to do a full rendering process (from the time it was taking).
The preview window keeps flashing "no recompress required" (took me quite a while to catch what it said).
Am I doing something wrong?
When I do the same thing in "Womble", it's over in a flash!
Darn good prog that Womble.

Except that Womble won't recognize 24p. It reports 24p as 60p, at least from my HD110. This has been reported to womble tech support.

Sony never commented, that the smartender function works with SD-mepg2 too. The technical specification says, that smartendering works for HDV and XDCAM HD.

However, as long as ist says "no recompress required", I assume that smartrendering takes place for SD-mpeg2. So be happy, that this undocumented feature works too.

If you want to test if smart rendering takes place really, simply use a short clip, and render that twice - with enabledn and with disabled smart rendering (in the options/preferences). And compare the render time.

I use womble in the German version Easymovie too - for simple cuts, taking out advertising from captured movies from a sat receiver. And I am not satisfied, since this Easymovie version generates a lot of additional errors in the material. However, Easymovie is an older version of womble. And you are right, womble is much faster, for sure.

Smartrendering in professional tools like Vegas 8 or Edius 4.5 seems to process the material in a different way, compared with womble. Even if no technical details has been published here, given the longer time for the process compared with womble, we can assume that some other calculations are taking place in the background.

If the footage is unchanged, then this "flashing" of the "no recompress required" doesn't sound right.

When I've tried it (on HDV), it will show "no recompress required" solidly (not flashing) when it is smart rendering. It would only flash if going back and forth between a smart render section and a recompress section.

Sounds to me like it thinks it can smart render, but then realizes it can't, then thinks it can etc. Sounds like it is trying to do it but can't actually smart render SD.
