Workflow: 24Pa > AE > Vegas

Curious, as I can't seem to figure this out--

While I can open and use 24Pa footage in AE 6.5 w/ pull down, how do I export it with the same pull down that it was interpreted at?

For example:

If I import 24Pa footage, the scheme is "WWSWW." When I go to render the footage, however, "WWSWW" is not listed under the possible pulldowns to add back in, so that I can reimport the clip into Vegas 5.

I'm sure it's simple & I'm missing it!

Hello Dave. If you are using 24Pa, do you need to work in AE with a pullown? It should be easier to capture your footage in Vegas, export it as 23.97, open that in AE, and work in a 23.97 timeline. If your footage was not too long, you could render from Vegas uncompressed and skip codecs. There are selections from the video options dialoge under the "Custom" settings for an DV export in Vegas which allow you to render 29.97 progressive, with a pulldown, with whichever pulldown you want, as well as rendering 23.97. I would think that would not only be the easiest, but best way for quality. That way, you are working with 24 fps progressive, and can set up a new vegas project with those settings.

I sometimes render 2 copites of everything from any program I work with, one with a codec and one uncompressed. Then, I do all the editing with the file with a codec and when it is time to render, replace all the video with the uncompressed files.

Thanks for the advice. It works like a charm.

I don't know why I missed the obvious solution!

so let me get this right in my head

export from vegas 24p> import into AE 23.976 > export as 23.976 then drop back into vegas


or export from vegas as uncompressed > import into ae 29.97 export as 29.97 then drop back into vegas.

I guess when doing uncompressed I am confused if you have insert a pull down when rendering out from vegas before you bring it into AE or vice versa so that it each program knows its 24p and not regular 29.97.:undecided

Ahh, I see the confusion. Basically, it goes like this: If you want to work with a 23.97 timeline, render from Vegas as 23.97. This will make it progressive by default. If you render it uncompressed, that has no impact on inserting a pulldown, as the pulldown is a way for a NLE to pull the 24fps out of a 29.97p or 60i video stream. Since you will be rendering from Vegas at 23.97, there is no need to ever work in a 29.97p or 60i timeline again. Vegas will do one hell of a job in the conversion. And, most programs will be able to instantly recognize it as 23.97 from the start, and After Effects allows you to then create a composition to the exact properties of the clip. Then you export from AE, and by default it will be to the correct settings.

BUT, this is if you are going to be working with the end goal of keeping it at 24. If you are going to view it on a TV, then you would have to take it from 23.97 and convert it back to 29.97. That could cause problems in editing and rendering. The DVX shoots 24p for the reason of keeping it simple. If you want the 24fps look but want to continue to work with your file in a 60i timeline, you can. No extra work needed, with the freedom of adding all the extra elements you want rendered at 30p or 60i. Just import the file, work with it, and don't worry about converting anything. It's quite handy.

The pulldowns are for getting 23.97 footage out of 60i or 30p, and the two different pulldowns, 2-3 and 2-3-3-2 are for 24p and 24pa respectively.

If you want to see what footage shot at 24p (not pa) in camera and turned into 24fps footage looks like, check out my thread in the DVX clips section. That's a DivX file playing at 24fps.
