Capture at 30fps, but imports as 24fps

Rebel with a cause
Can't figure this one out. I have a video file, originally recorded in F5 (24p), and then captured into a PPro 29.97 timeline. Once in PPro the file says it's 24fps. (Interpretting the footage just speeds it up.) Then, when exported from PPro, all the whites flicker (from the pull down, I guess). The clip prior to importing plays and looks great. PPro is doing something to it. Again, the project is DV NTSC and the file was captured in Premiere and also Windows Movie Maker to make sure the clip was captured at 30fps. The properties in WMM shows 29.97. But once it's imported into a 29.97 PPrro timeline the file changes to 24fs. Please help. Thank you for any assistance.

Edit: I just did a quick test in Sony Vegas and it rendered fine. It's definitely PPro doing something screwy. Never had a problem with this before.

I recall reading something about importing multiple clips that are at different frame rates and that causing a problem. Premiere uses the frame rate of the first clip for all the remaining clips. There's more info somewhere here on the site.

Does that sound like the problem you are having?
 
The only problem is the flicker thing right?

WMM thinks its a 29.97 file because that's what it actually is (a 24p file with 2:3 pulldown that distributes 24 frames over 60 fields giving you a 30fps video file). Premiere is clever enough to invert that pulldown and realize that it's really a 24fps file.

I've had a similar problem with the flickering whites, to be honest I don't fully understand what causes it. For me it only happened while I was crossfading (when it was just the clip with no compositing, I didn't get a flicker). Here's a couple things you can try:
-> Drop an NTSC Safe (maybe called "Broadcast Colors"?) effect on the clips
-> Drop a Levels effect on them (don't adjust it, just have it there).

These might help the white levels and shock Premiere into rerendering. Let me know if it works out.
 
PK, PPro doesn't handle 24p (normal) real well... there are some issues. If you shoot 24PA on the other hand, you can edit in a 24p timeline and all will be well.
 
Ah, the flickering problem. Sorry, I didn't read clearly. Yes, it's a PPro problem. As "overnighttolondon" mentions above, use the NTSF Safe filter. I think it's a problem of PPro raising the white level past the safe level for some frames.

I'll do a search to see if I can find more info.
 
The Levels trick worked!!! Didn't even need to adjust anything. Just drop it on the clips that have bright spots and it did its magic. Thanks "overnighttolondon" and everyone else. And thanks DVXuser too!
