Don't export anything from Premiere. Either import your individual original clips into AE and use the Interpret Footage command to "Guess 3:2 Pulldown" in order to generate 24p clips/comps which you then export or DL to PPro, or import your PPro project into AE and do the above process on each individual clip. You can't remove the pulldown en masse because of the way in which the pulldown is introduced; you have to go clip by clip. Since you've already done your edit (it appears) you're going to have to do some sequence-jockeying as you'll be changing the timebase of the clips and therefore will need a new sequence (24p, obviously).
My workflow would be to take the clips into AE, remove pulldown, and create a comp for each clip. After you interpret the footage, simply drag the clips onto the New Comp icon and select the individual comps radio button; this will create as many comps as clips, and name the comps the same as the clips. This makes media management a little easier as you know which comp belongs to which clip.
I'm assuming you've got the Production bundle, and therefore Dynamic Link. In Premiere, first save a copy of your project for safety, and then create a new sequence with a 24p timebase, and copy your original edit (all clips in the 60i sequence) and paste it into the new sequence. Now, for each clip you've used, select its master clip in the Project Panel and right-click on it; select Replace Footage. Navigate to your AE project and hit OK, and this will launch the Dynamic Link window; select the comp that matches your clip. The original clip and all instances of it will be replaced with the DL'ed comp, and will assume the 24p timebase. Repeat this for each clip in use. Unfortunately, there's really no automated way to do this, so it's a one-by-one deal. In the future, it's probably easier to do this at the outset instead of after the edit is done.
Man, that sounds like a lot of work. Might be easier just to leave it as is. The look won't change any. It'll simply take up more space on the disk.
in any case. I would still like to know how i should export the file (what codec+settings). On top of that, I don't even think i'm using the correct sequence settings...
PP automatically assigns 29.9700fps (yeah.. i know) and a lower first field scan. So i don't even know which preset to use... Help plz?
ok guys i figured out EXACTLY how to do this.
I edited my entire movie in premiere pro at 29.970 fps. I then imported the entire sequence into after effects through dynamic link, right clicked the sequence in the browser pane on the left side, interpreted the footage and then put the source frame rate to 29.976 fps and guessed a 24Pa pulldown YAAAY! i rendered a bit out and AE plays it back at 23.976 fps
