CS3: A large project with videos of different frame-rates

Ok - first, I apologize if this has been addressed recently - I have checked the forum and scoured google with no luck but I may have overlooked sources as I'm sure this is a common issue.

So I have a 30 minute project in Premiere.
The footage was shot with a Canon GL-2 in the 24 frame cine mode. The video files differ in their frame rates in the project:

23.976 for the videos I worked on in AE and exported.
29.97 for the raw footage

and 2 files in the mix that are 24.00, and 30.00.

My project settings are:

Editing Mode: DV 24p
Timebase: 23.976 fps

720 x 480
Pixel aspect: D1/DV NTSC Widescreen 16:9 (1.2)
Fields: No Fields (Progressive)
Display format: 24 fps Timecode

So obviously there is quite a bit of inconsistency in my project due to ignorance going into it. I am having issues with my export settings now - what I'd like is a clean, uncompressed 24p version that I can load into AE CS4 on another computer to do the color correction and final export.

Right now im exporting as:

DV AVI
DV (24p Advanced)
Frame Rate: 23.976 fps
Pixel Aspect ratio: D1/DV NTSC Widescreen 16:9 (1.2)

Keyframe and Rendering
_______________________
Fields: No fields (progressive)
Checked Deinterlace Video Footage
Checked Optimize Stills

So with these settings I am getting a very lagged looking video with ghost frames and interlacing. As a side note I tried a square pixel aspect ratio export and got the same thing but with a green distorted line at the bottom of the frame of some shots.

I am dealing with a deadline for this and I've just run out of ideas. I have read some solutions to conforming video using Interpret footage and changing the frame rate / pixel aspect ratio in there but I don't want to start messing with that if it will affect the video files themselves. If anyone can offer advice, solutions, or just point me in the direction of some information i'd be really grateful!
 
What are your files that are 24.000 and 30.000?

With the GL2 footage, right-click, go to "Interpret As" and see if you have the ability to remove DV 24p pulldown (if the checkbox is available).
 
The 24.00 is an export from AE - I just did that the other day so I remember that's because I plugged in 24 when I exported. The 30.00 I'm not sure, it's one of my original captured videos. (it's just a file with a few short pickup shots)

I see the greyed out remove DV 24p pulldown with no checkbox available.
 
The GL-2 footage is probably 24p in 30i wrapper (some people call it 60i, but it means the same thing)

AE has more pulldown removal options than Premiere. Test the GL-2 footage in AE to see if the pulldown removal there works. There are several manual modes/cadence that you can test in addition to "guessing". If this works, export out of there using a lossless intermediate or use dynamic link for Premiere

If that doesn't work you can use avisynth to removal pulldown, either with avs import plugin directly into premiere, or lossless intermediate
 
My question about using AE is, will I be able to just load all of my source videos (the media linked in the premiere project) into the render queue, process them to remove pulldown / change framerate, and then still have the files intact and linked by premiere? My concern of course is that I'll need to process each individual file as I have ~100 video files in the project.

I'm reading a bit about the avs import plugin and from what I understand i'd be getting a .avs file out of avisynth that would then need to be imported into premiere which seems like it would break everything? I'll keep reading.. most of the stuff I see about this is pre-cs pro and deals with strange file formats.

Thanks
 
if they were all shot in the 24p mode you should be able to remove pulldown on them in premiere. it appears that most of them have worked correctly and done that automatically. however the shots that still show up as 30fps / 60i may very well have been shot in that format in which case you would have to convert them to 24p somehow. otherwise you could just load them into AE and see if it detects the 24p for pulldown, and then just do a replcae footage command in PPRO after linking that AE comp with each shot into your ppro project, and it would replace your non pulldown clip in your ppro project with the 24p pulled down clip from ae leaving all effects and edits and such intact in your ppro project.

if ae doesnt detect 24p for pulldown as well, ..again the most plausible reason is because they were not shot in 24p.

hope it works :)

I'm not sure what you mean by "break everything"?

It creates a few kb .avs file that is similar to a proxy. It's a frameserver, so to Premiere it looks like your video clip, but with pulldown removed. There are batch avs utilities if you have 100's of these clips. The benefit is that they are tiny (compared to encoding to a lossless intermediate for import), the negatives are the extra step you have to take, and that there is more overhead for premiere (routing though the frameserver), and slower to edit than native footage

But I've had footage from canon cameras that none of the manual modes in AE could process IVTC properly (residual blends or combing). The only successful way was with avisynth

The "ideal" solution would be getting premiere to interpret the footage properly. It wouldn't hurt to make sure you have all updates and try again
 
By break everything I just mean breaking the media linking for the video files.
Neil, I'm really not sure why premiere isn't interpreting the footage properly, everything was shot in 24p mode and then verified. This was a borrowed camera so I had no idea what I was dealing with, I thought that shooting with that setting and setting the project for 24p would be all I needed.. maybe it's as simple as updating premiere.

Thanks for the info PDR, I'll be reading up on using avisynth if all else fails.

Thanks everyone.
 
if your worried about your project getting corrupted during the changes, just save it as a second project and then make the changes. hopefully it all works out :)
