I want my 24 FRAMES !

[wolff75]

How do I get 24 separate frames per second from 24p footage? (shot with dvx100a @ 24pa)

Instead of a 1 second mov running at 24p, I want 24 sequential images (ex: tgas or tiffs).

What is the proper way to do obtain/extract/separate those frames from the 24p movie?

Its not as simple as just exporting, and clicking on a "deinterlace" option. That option gives you some frames that seem to have been deinterlaced by duplication or blending of fields.

I shot footage for a music video with my dvx100a NTSC. The idea requires post: color correction, adjustments, masking, compositing, adding graphics, etc. For this type of treatment, the full frames give me more control that having interlaced images now and then.

I captured and edited with Premiere Pro 1.5, using the Panasonic 24P preset.

Once the editing was completed, I opened my premiere project in After Effects, and had all the separate layers to work each individually.

Now the problem is: I want those 24 FRAMES per second. I want to be able to see each individual frame. After Effects interprets the footage captured in Premiere (using the 24P preset), as being 29.97, separate fields (lower field first).

The movs I have all seem to be interlaced, both in Premiere and After Effects.

Help greatly appreciated!

your post is a little confusing hopefully i understood it properly...It seems as if your settings in after effects are set to ad a pulldown to 60i with your 24pa footage (more or less convertng it to 24p normal footage whihc you would edit as 29.97 lower field) You have to find the settings in after effects that allow you to no add a pulldown. When you recorded in 24pa and captured premiere should have removed the advanced pulldown for you and turned it into 24 progressive frames. In terms of exporting those 24frames after you fix those settings you have to export the timeline using an image sequence for the rendering codec instead of microsoft DV or MOV. You shouldnt have to deinterlace since your footage is already progressive when the pulldown is removed, if there is a lot of movement that would cause a shot made at a shutter spped of 1/48 blurry then that frame will just become blurry in the pic but you wont have to deinterlace like 60i footage.

Usually After Effects guesses properly the settings of a movie automatically. Thats why I became puzzled when it read my movies as being 29.97, separate fields (lower field first).

In premier, when I check the "interpret footage" settings, it says the file's framerate is 23.976

In AE, when I check the "interpret footage" settings, it says the file's framerate is 29.97.
If I change this in AE, using the "conform to frame rate: 23.976", a message appears: "WARNING: Audio May Not Synchronize". But I did it anyway, to check the sequence frame by frame, and still, every 5 frames or so, comes one that looks as if it was deinterlaced.

If I check the framerate on the Windows interface, I select the file, and check the properties. It says the framerate is 29 fps.

I'm guessing that Premiere Pro 1.5 captures the material @ 29.97, interlaced footage, but maybe "handles" it 24p - It knows how to arrange those fields to show you the full 24 frames. The reason for the 29.97 might be so the footage is more compatible with other NLEs.

When I go frame by frame in Premiere I never see that fuzzy frame - all frames seem to be ok and complete.

Let me try to export sequential files (tgas) and will report shortly....

(Thanks for your reply)

I think I got it. I just exported a TGA sequence, and then imported it into AE, and all the frames look ok. I did not click on the "deinterlace" option while exporting.
So, I got my 24 FRAMES !

I still have to check if the audio remains in sync.

And also, its disappointing that AE (v 6.5) can't "handle" the 29.97 intelaced footage, to behave 24p. It should be as simple as interpreting the footage @ 23.976. But as I mentioned, AE 6.5 wont show you all the full frames that way. I guess they still need to add that feature. Maybe they have and I'm not aware of it. Or maybe a series of settings set the right way will do the trick.

For now I have to render each cut in my Premiere sequence as a TGA sequence, and then replace each of the corresponding ones in AE to be able to work on those the way I wanted.

I'll add anything I learn in the process...

if you use the "guess pulldown" feature of AE's "ionterpret footage" function. you can match the proper pulldown on hte file and get it to play right. PPRO outputs as 24pa "33233"

And yes, I'm being quite confusing. Let me explain myself (if I can)...

Its seems that I achieved my initial request: to have 24 separate, full frames (24 TGAs).

But what I really was hoping for was: To have footage, in AfterEffects, that played at 24 frames per second (full frames). To go frame by frame, and not get that fuzzy, deinterlaced frame every now and then. That should be as simple as just interpreting the footage @ 23.976, as long as the Composition had that same setting, but that doesn't work.

So I thougth, if I can get those sequential frames, then there's got to be a way for a quicktime or avi to be converted that way also, to become a movie that plays 24 "progressive" or full frames per second, instead of a 29.97 interlaced movie that can be interpreted to behave 24p -- able to show you 24 frames.

Thats it, it sounds possible, doesn't it?

It works!

It works!

Wow, how did I not guess that? It works! It was simple, after all...

In AE, you go on "Interpret Footage", and down there there's a "Guess 24Pa Pulldown" option. Automatically the frame rate is set to "conform to 29.97", which is the same as the file frame rate, so it wont make the audio go off sync.

Note: to be able to go frame by frame, the comp has to be 23.976. If it is 29.97, then you'll get duplicate frames now and then.

Thanks man!
