Project vs Media File Properties
I’m trying to sort out all these property settings in Vegas 9. My understanding is that Media File Properties define how Vegas interprets data coming in from a file, while Project Properties control output into the rendering engine. Is that right? The manual is confusing me a bit on Page 269 where it uses output-oriented language under the “Field order” media property.
At the other end, what happens if the rendering codec is set up differently from the Project Properties? Does that cause the codec to reinterpret the input? Or does it only affect the rendition?

I grabbed this explanation some time ago and I think it does a good job of explaining things.
Project Properties drive the preview.
For example, you keep Project Properties at DV and then add all HDV on the timeline.
As you play your project, Vegas scales the HDV to DV for preview — result: your computer works harder and you probably can’t sustain full frame rate.
So, you should always set the Project Properties to match the majority of the clips on your timeline for the best playback performance.
It also makes sense to set with the output in mind, too (e.g. widescreen vs. 4:3).Also note that all generated media, titles and such, are scaled to match the Project Properties.
So keep your resolutions and aspect ratio in mind for that too.When it comes to the render, you can indeed override the Project Properties and render to anything.
Vegas does its conversions during the render.
