I can't believe I'm asking this, but...

This is the one subject where I have been continuously confused and SWEAR I've heard contradicting answers before, but here it goes.

Please forgive me for asking such a noob type question.

I shot footage in 24PA on my DVX100B. I created a project in Premiere Pro CS3 as a 23.9(whatever #'s) timline, because according to Adobe that's what it says to use for footage shot in 24PA.

2 questions: 1, did I capture this correctly? Or do I have to start all over again?
2, how do I export this so that when it plays on the web (I.E. vimeo or something) it doesn't look super interlaced?

Please help, I'm on a very crunched schedule here, this question is regarding my TwilightFest entry, which I only have a few days to edit.
 
yeah. I don't use premiere so I can't say with certainty, but you should not need to select that since the footage is already progressive.

If you brought the footage in properly and are editing on a true 24p timeline, you should be good to go. Just have to export properly.

when you're working on a 23.98 timeline with footage you shot 24pa - there should be no interlacing AT ALL. Not for web, DVD, filmout whatever.

I don't use premiere either so this is general information that should apply to working with 24pA in post.

Your camera shot 24pa. This is 24 over 60, but it's tagged certain frames, the interlaced ones, to be removed later by your NLE or on import to your NLE. That's what the "A" stands for Advanced pulldown.

When you've applied the Advanced Pulldown, there are no more interlaced frames. Your NLE, either on import or later throws them in the garbage. Now you have 24 (23.98) frames left and every single one of them progressive. Your footage is no longer 24 over 60 or 29.97. Repeat, you're footage is no longer 29.97 it is now 23.98 because you've thrown away frames and should be worked with on a 23.98 timeline.

If you frame by frame through your footage and see an interlaced frame every 4 or 6 framess then you have not applied pulldown.
 
The footage (unless you're using CS4) should already have pulldown removed and be read in the project bin as 23.976. If not, right click on the footage, select Interpret Footage and there should be an option to remove pulldown.
 
Do NOT use any deinterlace filter. Just capture the footage and edit in a DV - 24p timeline. That's all you have to do, whether it's 24pA or 24p standard.
 
One place where interlacing does sometimes crop up with 23.976 footage is if you export out of Premiere in DV AVI codec.

I haven't used Premiere since CS2 I think but I used to have this problem.

You're working away on a 24p timeline and then you export as DV AVI. But the DV AVI codec is NTSC (or PAL) only - so what you export is 24p over 60, and unless you're in a smart application like Premiere, you're going to see the interlacing.

So export as high quality WMV or H.264 or something for your Vimeo uploads, 24p / progressive / no deinterlacing filters.
