Interlaced Video - 24pa/PPro2.0

I am relatively new to video editing and I have a problem that I can't seem to solve. All of my video turns out horribly interlaced. I've spent countless hours reading this board and other web sites but still haven't figured out what I'm doing wrong.


I have shot several short films on a Panasonic DVX100b in 24pa (scene setting 6). I then start up a new project in Premiere Pro 2.0. When doing so, I choose the 'Standard 48KHz' option under the 'DV-24p' heading. Then I capture the video with Scene Detect enabled. I have verified there are no breaks in my time code.


When previewing the video in the PPro editing window, I see interlacing all throughout my video. However, I understand that I'm not really supposed to trust that window. The real problem comes when I export that video. Primarily, I'm trying to export small WMV files that I can upload to YouTube. I use the Adobe Media Encoder and choose to export the file as Windows Media. I've tried dozens of combinations of settings, but all my films end up with terrible interlacing on any shot that contains any sort of movement.


I've exported video with the 'Deinterlace' option in the Output tabbed checked and unchecked. I've tried it with the 'Allow interlaced processing' checkbox under 'Basic Video Settings' checked and unchecked. None of that seems to have any bearing on the finished product. The only thing I have found that works is to right-click on each individual clip in my timeline, choose 'Field Options' and then check 'Always Deinterlace'. The problem with that solution is that I have to click every last clip in my timeline (which gets bigger with each new project) and doing so seems to degrade the quality of my video.


I've wrestled with this problem for months and am no closer to solving it. Can someone help me out here? Am I doing something obviously wrong?
 
What did Premiere interpret your footage as in the project bin? 29.97 or 23.976? If it's 29.97 then the pulldown weren't removed and that's why there's interlacing.
 
Well you said you used "DV-24p" but you shot in "24pa" that might be the problem.

Actually, that probably doesn't mean anything..... I read somewhere not too long ago that when your capturing you could be missing your 24p flags or something.

EDIT******

go to custom settings in the new project window, and set the editing mode to desktop. from there you can uses whatever editing codec you want and use whatever framerate you want and any other custom settings you would like that you have availabe to you on your machine through any plugin ect.

Read that in another thread.

jade, when viewing the properties for my footage, the framerate shows up as 29.97. when i look at the general project settings, the timebase shows up as 23.976. is this the problem? is there a way for me to switch my footage to 23.976? and how do i force premiere to import my footage at the same framerate as the project timebase?
 
That is a problem. The pulldown haven't been removed, hence the interlacing. Try right clicking on the footage in the bin, select Interpret Footage. If the footage is really 24pA, the box Remove 24p DV Pulldown should be available, check it. If it is blanked out, it's possible you should 24p 3:2 instead. Try using a 29.97 timeline instead.
 
well this is rather frustrating. the option to remove 24p pulldown is grayed out and the 'frame rate from file' appears as 29.97. when i look at the settings in my camera, it definitely says i'm shooting in 24pa.

you have been kind to help me this far. do you have any other suggestions?
 
Do you have After Effect? If you're really sure that it's 24pA then you can import it into AE. Interpret and tell it to "guess" the pulldown. This will confirm whether it's 24pA or not. Since AE contains pretty much all of the possible pulldown algorithm, it can remove the pulldown for you but you'll have to render out the file uncompressed before editing, which might be a pain.

Otherwise use a 29.97 timeline and see if there's still interlacing.
