Project rendering revisted

Could someone tell me how to identify the reason why VV3 often decides (without apparent need)to re-render a project on printing to tape. I am working on projects in excess of 10 minutes but sourced from DV and cut only edit, so I don't expect to suffer the delay of re-rendering. However I face frequently "80% of your project must be rendered - do you wish to proceed". Strange thing is that I can play the project in real time from the timeline no problem without re-rendering! Is there anyway I can work out what is causiing this? Premiere seems to have no issue and prints to tape immediately. Premiers also shows any mismatch between output format and source format to help pinpoint these issues. Possibilities/suspects include frame interleave output selected and different dv source codec (microsoft). Thanks John I

Hello John,

The way I understand it, this issue is most often seen when codecs other than Vegas are used... Capturing and outputting using Vegas' codec is usually a remedy. Users report that other capture/codec methods are accepted by Vegas without rendering, Scenalyzer being one that comes to mind.

You might run a test with a short Vegas-captured clip to see if you have your project-properties and capture settings configured to permit a "non-render" print. When you got that squared, you can try applying those project settings to a copy of your current project to see if it resolves. If not, your capture codec may be hanging you up...

Other issues that might be involved include: opacity changes on a track, a foreground track in a compositing mode, rendering to other than "good" quality, rendering to an audio sample rate other than 48k, deinterlacing, or a template other than DV.

Some of the material was rendered on a different PC and almost certainly a different DV codec (probably Microsoft). Thanks for the comments, I will experiment further. However I do come back to the point that Premiere is much more forgiving/flexible in this respect. Also more helpful in helping you find out why a render is required. VV3 is good in other ways though. Thanks John I

Look at the media properties for two clips, one that requires a render and one that doesn't. What are the differences?
