Why would this happen??? Previous Vegas results were different.

Please bear with me as I explain this dilema.

I've got a project with multiple graphic files. All pictures are being paned, zoomed, etc... Some of the pictures include a person with a top that has horizontal lines on it. Well, when rendered for DVD, the image results in poor quality. It's like the top is dancing with jittery movement. From experience, I'm aware that such problems are going to happen with such a picture.

So, to correct the problem, I simply add "gausian blur". If I do a test render using just the one problematic picture, the results are fine. Namely, the blur helps reduce the jumpy type result.

Now here's what I notice. If I render the entire track, the "gausian blur" no longer seems to be applied to the render.

In other words, the resulting mpeg files are different. One has blur, the other does not. Why would this happen???

A thought crossed my mind and I tried something. Now get this, what I did was open another instance of Vegas. From the original project, I copied the entire track and pasted it into the other Vegas running. I then tried the render and lo and behold, the gausian blur is now taking effect.

What in the heck happened here? It's the same project open with two different results. Was it just an unsual glitch?

Has this ever happened to anybody else? Any ideas?

Never had this happen so I cannot comment on your Vegas problem but a trick I worked out with the blur to stop the aliasing problem.
Well first (onviosly) try Reduce Interlace flicker, seem to fix more than just interlace flicker. If that fails resort to blur but only apply it in the vertical direction. You can apply quite a bit in the vertical before it becomes noticable. Then I've applied the Unsharpen Mask but this time to sharpen the horizontals. Overall effect is to 'fatten' thin horizontal lines without them looking too soft.

PS, you didn't have FXs bypassed in the project where it didn;t work right?

No bypass used. Remeber, I would get the blur working if I rendered only a small portion. When I rendered the entire track, it would not work.

As for your various suggestions, I'll give them a try.
