AE Dragging with 4.5min. 23.98fps .mov

[Ryan Izzard]

Hi All, I'll try to keep this brief...

I shot a 4.5 minute music video using the DVX, and edited it in FCP HD 4.5 at 23.98fps. Now that I'm done my edits I've exported the video as an uncompressed 23.98fps quicktime file and than imported that file in After Effects so that I can clean it up and add some effects.

The problem I'm having is that when I click the play button in AE it drag's so bad it only plays one frame ever 30+seconds... and if I try to advance one frame at a time manually it still takes 30-45 seconds to advance and often locks up for long periods of time and/or crashes. It even takes long periods of time for the app to respond when I paint or rubber stamp a frame... and will also lock or crash during this as well.

I've tried this on multiple Mac's; PowerBooks, G4 Quicksilver and a G5 all with 2-4GB of RAM running various OS's and instillations of AE so I'm confident this is a software setting problem.

I've tried changing my comp fps to 23.98, 24 and even 30 but nothing works. I'm almost done this project but can't see to cross the finish line becauase of this problem so if anyone has any idea why this is happening please let me know.

Cheers,

Ryan

how big is the uncompressed quicktime file?

have you tried other formats?

It's about 6.5GB. I haven't tred any other formats at this point. I've worked with Apple and Quicktime for years so I'm pretty confident it's not the file. It's still frustrating though. : -)

AE is not really intended to be used for realtime playback untill the project is rendered. even if you just put a simple DV file on the timeline it might not play it back realtime pending your hardware power. i think you need to use a lower resolution for previewing. or use adaptive resolution so that it automatically lowers the res to keep speed up. AE takes enough time trying to do DV at full res .. i wouldnt want to see it choke on uncompressed footage at full res.

I'm doing uncompressed 10bit all the time and let me tell you..it ain't gonna scream..it's AE, so if you want a preview of color correction and som other stuff I would not lower the resolution but rather render it out..make sure you select only a segment to render.. to give you an idea. whenever I do any spot it takes in an average 1.5-2 hrs to render 30sec, and I'm doing fairly simple stuff.. blurs are gonna choke your bandwith so leave out effects like that for final render.
AE has also thing called proxy which is perfect for such projects. file-proxy-create still ... or something like that..
