taking the pulldown out (space issue)
I have a 95 minute movie in an AVI file that’s only 20.6 gb. It’s 24pA and I need to convert it to true 24p.
I put it into after effects and took the pulldown out and am rendering it out to 23.98. But, it’s creating a file that’s WAY larger than the original. It says I don’t have enough space and I have 43 gb free!!!
Why is it so much larger? How much larger is it going to be? Is there any way to keep it closer to the original?

As for the 3rd point Dave. You are, of course, entirely correct 🙂
But we don’t know yet whether it was edited without removing the pulldown. It’s possible that this is raw footage or that it was edited somewhere else with the pulldown removed, and had the pulldown re-introduced when it was put to tape (In reality, I find that most ‘professionals’ manage to miss one of those steps… but I can dream can’t I?)
So, where is this footage coming from?
And to answer the original question, the files are most likely larger because you are rendering out to a lossless format. This prevents any generational data loss, but requires a lot of HD space. You could render back out to the codec that your footage was originally. You will suffer minor generational loss, but it sounds like it may be your only option.

Don’t worry, none of those problems exist here. (unless you consider making a movie in SD a problem)
In Adobe Premiere the pull down is automatically removed and edited in a 23.98 timeline (or 23.976 if you want to get specific). So I’ve already taken the 24pA pulldown out in AE, that’s not a problem at all. It’s just a space issue. Apparently Premiere automatically adds a little compression when it exports (and you can’t export without it apparently). It calls it 24pA compression whatever that actually is.
I could get a 500 gig external HD, but how large would the actual file be for a 95 minute avi file rendered out lossless?

I find that it’s usually around 1.5GB/minute. It depends some on what your material is. To be safe I’d say 2GB/minute.

I appreciate your response. Premiere is pretty weird about this stuff. I always feel like I’m playing catchup trying to figure out what it’s doing. ha.
When you create a “Panasonic 24p” timeline it automatically takes out the pulldown and when you export it puts it back in. To my knowledge you can’t export as true 24p for some weird reason! If it is possible, I’d like to know how!
Where it says “24pA compression” you can change it to “NTSC compression” which I’m assuming puts a 3:2 pulldown when it exports but that’s just my guess.

I did. Thanks for the sarcastic advice though lol
