Help! - Big rendering problems with vv4

The problem is actually not only w/vv4, but with vv3 after having installed vv4 and/or DVDA.

When I try to render an AVI to DVD MPEG2, or even to another AVI, I'm getting horrible artifacts when I use a letterbox (so the image doesn't get clipped on the TV). It looks like a really bad rippling effect when there is fast movement. You can see it in the preview window when the file is being rendered, and you can see it on the final DVD when played on a set-top box (though it looks okay when I play it on my PC). Please see my screen capture of the preview window so you can see what I'm talking about.

I never had this problem with VV3. What happened???

TIA

Did you uninstall V3 before loading V4? Sonic Foundry recommends that.
Hope that helps.

I may be way off-beam here, but I've seen this in the previewing of rendered files while working in U-Lead Movie FActory. But when burnt to VCD or SVCD, it looks good to me. As I say I may be way of beam here. Oh, have you tried to change the Preview Screen to imitate the device. Again I'm on weak ground here, but before you apply some "drastic" remedies have a rethink on the Previewing.

I did uninstall VV3 before installing V4.

I'm not concerned about the preview. I am concerned about the fact that this is what the final DVD looks like.

I didn't see where there was a recommendation to uninstall VV3 before installing V4. Where did you see that? I think I remember a recommendation to uninstall the v4Beta before upgrading, but not V3.

BTW, I have VV3 and V4 both running just fine on my system. Didn't want to convert all my old edits, some of which reside on external drives.

I think both programs should be working fine . . . and would look to some other source of this poster's problem.

Me too - VV3 and V4 AND VF on same system drive no problems here. In fact V4 has even picked up some hard won presets I created in VF - amazing.

Okay -- big update on this problem. Turns out it has nothing to do with VV3 versus V4. I reverted my system to an old configuration with VV3 installed, and tried it again, and still got the rippling. I started thinking that perhaps it was the DV file itself causing it, but then tried it with another file.

Turns out that the reason it was happening was because I was using the TRACK pan/crop instead of the EVENT pan/crop to letterbox the video. When I use the event pan/crop, it looks just great. Use the track, and I get the horrible rippling effect. (Again, I must stress that this comes out not only on the preview, but on the final DVD, if rendering to MPEG2, though the rippling happens no matter what format you render to, including DV).

So, would this be considered a bug in the Track Pan/Crop tool? It happens in both Vegas 3 and 4 -- try it and see!

Is your Rendering Quality set at Best? If it is set to Good (the default), and you use any Pan/Crop, it will produce the rippling you experienced.

I was trying to set it to best -- as you mentioned you have to do it by hand, so it's possible I forgot, but I tried it so many times, I'm sure I had it set to best. I'll check again when I get home. But my tests this morning seemed to indicate that the Track pan/crop = bad and the event pan/crop = good.

I just confirmed. Highest quality settings when using the track pan/crop result in the ripple effect.
