Project Settings: Meanings?
I asked before but had little luck.
What do the project properties actually do? I have tried settings all over the place and they seem to make little if any difference to the rendered result. The only time I have seen a difference was when I set the AR of the project to a silly figure and got a strange AR rendered. Frame size otherwise seems not to affect the rendered output. Even the Best rendering quality setting is apparently over-ridden by renderers’ settings.
I _think_ I did see a difference once when I was playing with interlaced stuff, where I git a better result by using Interpolate fields and not None or Blend. But as for the rest I cannot see how they interact with the render. Yet I am always being exhorted to get the Properties right, usually to match the source. But what if I am working from several sources with different characteristics? etc.
Any help appreciated.

OK. I did some really rough experiments.
If I set the Project Properties, _some_ of it affects the way the _preview_ works (amaller frame size = smoother preview, but with pixels…etc).
But if I set the “wrong” Aspect Ratio, it stuffs up rendering as well. AFAICS no other settings make ANY difference to the render. Just how I preview.
The lower pane of the PP settings may or may not affect the output, depending on the renderer I use: if it does not take care of the parameters that I set in PP, then PP will take over.
I get the feeling that Project Properties is a Cinderalla setup, that needs re-vamping badly….no…that badly needs re-vamping.
Hence the fact that I am being told to use this and that, but nobody has been able to tell me why.
Please feel free to correct m,e if I am wrong.

aaaaaaaaaaaaaaaaartggggggggggggghhhhhhhhhhhhhh! and even then I thought I saw better preview as I set lower quality PP…then that stopped as well, and it was _Preview Quality_ that made it smoother if less quality.
So WTH _does_ PP do? Still seems a mess.
Please correct me. I keep asking.
EDIT: Let me put it this way. I am willing to put up with various levels of quality and smoothness when editing. I can see where the PP and the Preview Quality settings work there.
But _always_ I am told that in order to get the right render, I _have_ to have the right PP settings. I can’t see how it ties in with rendering.

Nick, I’d recommend reading through Vegas help on this topic. There is a button in the PP that allows you to match it to the media you are editing which may help you out.
Good luck

Thanks for the reply.
I have read the Help. It tells me how. But if I am a “good boy” in setting Project Settings I do not see the difference, except sporadically, to the RENDER….and then the ONLY time I have seen an effect was if I set a really CRAZY aspect ratio. NONE of the other settings seemed to make any difference.
BUT I AM ALWAYS TOLD THAT PROJECT SETTINGS ARE CRUCIAL.
WHY? WHY?/WHY?
WHY do I match it to the source?
What happens if I have various sources….frame sizes/rates?
Have you had a production where your first source was 1080p, the next bit 720i…etc and you had to give a reasonable output? So you are going to have greyscale and colour issues, and what have you.
But do the _Project settings have any effect on the rendered video_?
So far the result has been sporadic for me
AAAAAAAAAAAAAAARRRRRRRRRRRRRRGGGGGGGGGGGGGHHHH\

OK. Just saw a vid. IF you are having trouble previewing smoothly THEN try fiddling about until some result is achieved.
As far as I can see the Project Properties is at best a fluid tool. not of any great consequence.
I will continue to work with that assumption as my efforts to find out more have been for nought or NADI. Back to worrying about rendering.

[Nick White] “BUT I AM ALWAYS TOLD THAT PROJECT SETTINGS ARE CRUCIAL. WHY? WHY?/WHY? “
Because the project properties affect the video preview, and the video preview is what you are using to make all of your editing decisions. If you’re making editing decisions based on inaccurate data, your render is likely to not resemble what you expected.
From reading your posts I can see that you’ve already seen that not getting your Aspect Ratio correct will indeed affect your render. All of your cropping an positioning decisions are made based on the aspect. If you get that wrong, things wont be cropped or positioned correctly in your render (if the render uses a different aspect).
I believe you also mentioned that getting the Deinterlace Method correct is also a critical setting. This is correct. If you don’t tell Vegas how to deal with interlaced footage, you will get a mess when you render.
So it’s not that the project properties directly affect the render, but it will affect how you edit, which will in turn, affect your rendered output.
[Nick White] “WHY do I match it to the source?”
This makes sure that you are making edit decisions based on the true resolution and aspect ratio of your footage. If your project properties don’t match your footage, Vegas will convert your footage into the project properties before showing it to you in the preview so you will be editing based on the project properties and not your footage properties (but this may be desirable sometimes as seen in the next answer)
[Nick White] “What happens if I have various sources….frame sizes/rates? “
Then you have to decide what you want to use to make your edit decisions. In this case, I usually set the project properties to match my delivery format. If I have multiple delivery formats, I set it to make the highest resolution format. The real key is that you have it match the delivery aspect ratio so that there are no surprises when you render.
[Nick White] “But do the _Project settings have any effect on the rendered video_? “
Not directly. The project properties affect how you see your footage while editing and indirectly affect the rendered video if you were making edit decisions in one aspect and then render in another. Also the Deinterlace Method is crucial if you are using interlaced footage so that Vegas knows how you want to handle the interlacing.
Does that help?

I am very sorry I have not replied to this! I never had a notification. You put some real effort to help and I think you for that.
Yes it does help, to a large degree. But I now see that although I have read some very assertive statements about how to use the project Properties, I seriously need to work out my own road based on the computer I am using, among other things.s.
For instance if I try to set the PPs to be 1080 50p (my source, as is often suggested), I have no hope of getting smooth preview unless I use a very poor quality preview window setting.
I shall explore. It was the assertiveness of many tutes and other sources, without real reasons being given, that threw me.
