Vegas now rendering unaltered events - why?

I have a DV project with some transitions, effects, etc... but much of it unchanged. A few days ago when I did a render to DV, it did as I would have expected - took longer to render the bits where I had added transitions etc, and on the untouched bits it would speed through faster than "real time" (even on my slow 750 Mhz PC). In these parts the preview would stay on a fixed frame. It took about 2 hours to render the 1 hour video.

Now, having only removed some footage, Vegas 5 seems to be trying to do something to all the video... i.e. it seems to be processing every frame, even those which are untouched... and is taking about 6 hours to render to DV.

I can't figure out why. I've checked that the file properties match the output (PAL project, using PAL DV template). The levels on all the video tracks are at 100%, there are no track effects turned on.

This is driving me crazy... any other places to look?

I've done several test renders a loop on an event which has had no changes applied, and the same thing happens - a slow, frame by frame render, rather than just the fast "pass through".

It's not just the longer rendering time which is bothering me; I assume if Vegas is doing some processing that it shouldn't that it will impact the quality of the output.

Help!

You have certainly checked the things I would... except one thing.

Have you perhaps applied an FX to the preview monitor window? Not the sort of thing I would expect you would foget - but worth a try.

Just a check - what happens when you load the same clips into another project - does it do the same thing?

I had some problems like this that cropped up when doing a 'save project with media' . Some of the DV files had stopped being recognized by Vegas as proper DV avi format - check your media properties of the files that are giving problems.
This topic has been discussed on the forums a few times but the only resolution I have seen is to render out the file as a DV avi and re-import into the project - haven discovered why the files lose their DV avi status

One thing that will cause this is accidentally reducing the track "level" slider below 100%.

Liam - you are a star! Somehow I had a Fx set on the preview window... I must have done this accidently, I didn't even know that was there! I took this off and all is well!

I really appreciate the tip - it would have taken me forever to figure that out!

Glad I could help... it is sometimes a struggle to recall everywhere that FX's can be applied (that's both a blessing and a curse).
