Graphics shrinkage

We're having an odd issue. We have a project in Vegas 9.0c HD 1080-60i shot on HDV. The footage is just a lecture and I have built some graphics, in this case some maps, in Photoshop CS4. The maps were built in Illustrator and then enhanced in Photoshop. Most of the files are about 2300x1080 to allow for some panning and the pan/crop format is set to 16x9.

When we render to Mainconcept mpeg 2 with the DVD Architect template the graphics shrink horizontally so that the layer underneath, the speaker, shows at the edges. This is not evident in Vegas, only when the rendered program is played on a DVD player or in DVD Architect. The underneath layer renders fine -- it's just the graphics layer. And the problem seems to only happen in certain programs

I have tried adjusting the crop to get rid of the problem, but no luck.
We can work around it, but it would be nice and cause less headaches to know what is causing it.

Thanks

Your problem is that HDV's 16:9 is not exactly the same as SD's 16:9. So when Vegas downscales it slightly pillarboxes the HDV exposing graphics below at the edges of the frame.
There's a switch "Stretch video to fill output frame size (do not letterbox)" in the render dialog that should prevent this.

Your other alternative is to nest your HD project into a SD project and render from that.

Open the Pan/Crop window on an image, right-click in the centre of it and select "Match Output Aspect".

Ahhh. I learned a lot here. Thanks much Budwzr, Bob, and Mike. The stretching in the render box did the trick, but all are most helpful.

All appreciated. Good forum. Thanks.

Actually I do, but I haven't used a DVD in so many years I forgot. That's the anamorphic hack.

===============================================
"When I do that I cut the height to 400 to avoid the stretch."

That is completely the wrong thing to do! You don't even understand the most basic principles of PAR and DAR. God help the poor souls that come here looking for help and end up taking your advice.
