Does a nested veg file take on the properties of the new project its nested in?

Somewhat. The contents of the nested veg remain independent of the properties of the timeline in which the veg has been dropped. For example, if you drop 24p timelines into a 60i timeline, it will continue to be 24p, but now pulldown will be added.
You can affect/effect any nested veg just like video. Think of a nested veg file like a rendered or captured video file, it may help. You can split, add FX, pan/crop, Track Motion, composite any nested veg just exactly like a video file. But…like a video file, the veg will be converted to the project properties of the host project, should there be any mismatch.

Thanks for that info. I was concerned because the properties of the veg files can have instructions re things like, rendering quality, progressive or interlaced output etc.

Thanks in advance

Very interesting question!!

Soon I’ll be taking a nice long (14 hour) flight. I wanted to bring my laptop along to work on some lower thirds/graphics for an HD project. However my laptop is not powerful enough for HDV and I thought I could use lower project settings so I could keep my full frame rate previews. I was going to use a DV widescreen project as sort of proxy project template. And then when I arrived back at my workstation I was hoping I could just change the project settings to HDV and voila!!! my generated media would magic rescale perfectly. Well after reading the above post I decided to do some tests to answer the question:

WILL MY GENERATED MEDIA CORRECTLY RESCALE FROM LOWER RESOLUTIONS PROJECTS TO HIGHER RESOLUTIONS PROJECTS AND DIFFERENT ASPECT RATIO SETTINGS?

sooooo…

I generated some lower thirds and titles in a Multimedia (320×240, 15.000 fps) project. I rendered it, took at look at the quality…obviously not great. I saved the project and then dumped the veg on a new HDV 1080-60i (1440×1080, 29.970 fps) timeline – once again I rendered it to see the quality. No difference, it still maintains the qualities of the Multimedia project including the aspect ratio, which would corroborate Spot’s answer above.

Also:
I opened up the original Multimedia project i used and changed it’s properties to HDV 1080-60i. Now i don’t know if you’ve ever noticed but in the Video Event FX window it displays the resolutions of the generated media. In this case, even when the project has changed to higher quality settings the generated media keeps its original resolutions of 320×240, the aspect ratio again stayed the same.

I decided to physically go through and change the resolutions of the generated media, in this case 320×240 to 1440×1080(the new project settings), the media “lost its way” …meaning my lower thirds graphics didn’t scale up properly. Previously butted images now had gaps between them and vice versa, and the titles had also moved.

I thought this might have something to do with the aspect ratio change of the project and not the resolution, so I did the same thing only this time I started with media generated in a 16:9 DV project. Once again I changed the DV project to an HDV project and again I physically went through and changed the resolutions of the generated media from to 720×480 DV Widescreen to1440x1080. Scaled better but not perfect. Once again previously graphics the butted up against one another had gaps between them and vice versa, and once again the titles had moved

So…

WILL MY GENERATED MEDIA CORRECTLY RESCALE FROM LOWER RESOLUTIONS PROJECTS TO HIGHER RESOLUTIONS PROJECTS AND DIFFERENT ASPECT RATIO SETTINGS?

NO!

Just something to keep in mind if you are going to repurpose some generated media for higher resolutions or different aspect ratios projects – you’ll almost always have to readjust everything!
