Does the timeline really have any impact?

I'm already re-rendering a project just in case, but does the timeline really have any impact on the final render?

For example, all my clips were shot 24PA, brought into a project, then rendered out 24P (23.976). I JUST discovered yesterday that I never changed the project settings from interlaced 29.97 to 24P (23.976).

Does the timeline have ANY effect at all, or am I just wasting my time fixing the project settings & re-rendering the file? If it timeline has no effect on render, then it could even be set at PAL 25fps, 12fps, etc. and the clips/render still wouldn't be effected for quality/look?
 
I wouldn't think it would effect quality or output for example I had a clip that was shot in 24pa brought it in on the timeline and it ended at 05:23 sec. changed the timeline to 29.97 and now it it ended at 05:28, still had the same number of frames and no difference, though it could get hairy if you were editing an hour long film, if you shoot in 24pa I personally would set the the timeline to 24p as well imo.
 
I'm re-rendering because I now have it at 24P, and thought it was already there the entire time I was working on the project ... I was beyond frusterated when I realized what had happened.

How can it not effect the output/quality if by changing the timeline you had FIVE entire seconds added to the length of the project? That doesn't sound right ... number of frames per second may be effected and interlaced vs. progressive, but additional time shouldn't have been effected, I don't think.
 
bdt09, did you change the RULER to 29.97 when you changed the project properties? If you didn't do it manually, then it didn't get changed, and that could explain the time difference.

If you're editing on a 24p timeline, you're working in pure 24p and you will elminate any interlacing. If you remain in 29.97, you will see interlacing.

The good news is, you can switch on the fly.

However, just to see what would happen, I brought a 24pA clip into a 29.97 timeline and rendered out as 24p with 2:3:3:2 pulldown. The result was a clean 24pA file with no quality loss that I could see.

Which would be fine for just straight rendering, but if you're working with effects, text, etc., you want to work in a 24p timeline, because when you do, Vegas will optimize them for 24p.
 
Thanks David for responding. Taking your advice you gave to bdt09, I manually changed the properties to 23.97 on the ruler, and it did actually look like my project was about a second shorter (the ruler expanded slightly).

I also noticed that whatever I changed my project settings to, the properties of the text, etc. would automatically change as well ... NICE.
 
ahhh..... i think i misunderstood the question I thought he was in a 24p project but had the time ruler format set to 29.97.......I didn't actually see a 5 second difference the clip itself was 5 seconds so i saw 00:00:5:23 change to 00:00:5:28, great now I am all confused.
 
That makes perfect sense, actually; the 23rd frame of a 24p second will end up part of the 28th frame when pulldown is added to make it 60i.
