Problem With No Recompress Render Of HDV

Seth wrote on 11/19/2008, 2:44 PM

How long should a no-recompress smart render take on a mid-range system (2.16GHz Core2 Duo, 3 GB RAM) for an hour of HDV? It should real-time or better, since it's technically not rendering anything but cuts, right?

I'm rendering a tape back out which I had captured in HDVSplit, but needs to be rejoined at the split points to print back to tape as one file. Vegas is telling me that the render will take 14 hours. This seems pretty bogus. Is there any indication in the render window that Vegas is using smart-render, or is it 'seamless'?

Should I just print back to tape one clip at a time?

in the preview screen it will say no recompression needed, or something like that,, otherwise its rendering

I've checked to make sure that my project and render settings are identical to the media on the timeline. In Preferences I've set no-recompress as active. What else might I check to ensure that no-recompress rendering starts working as advertised?

Use a free utility such as MediaInfo to give you more information.
In particular, pay attention to bitrate, cbr/vbr, field order (important!), frame rate, and audio. Get enough right, and it will smart-render!

Thanks for the replies. The footage I'm asking Vegas to smart-render is 24pf HDV from the HV20, which is the source of the trouble, I think. I just crash-recorded the individual clips back onto a blank tape one at a time, as it left my workstation available for use within 45 minutes instead of 14 hours.

Do you render that HV20 footage interlaced or progressive?
