hey guys so ive been working on an edit in fcp 6.0.6 and once i was finished with the edit i was taking each shot into after effects cs3 and grading it and doing other effects to each shot there. The process was that i was exporting a quicktime reference movie of each shot and working with that in after effects and then exporting a quicktime movie of the same codec (xdcam ex 108030p)and puting it back into fcp . It plays fine in the standalone quicktime player but once in fcp it wont play smoothly at all... it shutters, stops, freezes on a frame and more... the specs are exactly the same as the sequence and the orig clips, so i cant figure it out... any help at all would be great..

i apologize if this is a common issue but i couldn't find anything in the forums..

apple g5 dual 2.7
6.5 ram
fcp 6.0.6
AE cs3

Oh, it's a VERY common issue for pre-CS5 versiuons of AE. Read on:

Dave's Stock Answer #1:

If the footage you imported into AE is any kind of the following -- footage in an HDV acquisition codec, MPEG1, MPEG2, AVCHD, mp4, mts, m2t, H.261 or H.264 -- you need to convert it to a different codec.

These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.

In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.

I'm a Mac guy, so I like to convert to Quicktime movies in the Animation or PNG codecs; both are lossless. I'll use Apple's Compressor, Adobe Media Encoder or Quicktime Pro to do it.

It is the XDCam footage -- even if exported by reference out of FCP -- being used within AE that's causing the problem. You need to change it.

Oh did you mean you convert it to animation before AE or out of AE?

Convert before going in AE, render out to an uncompressed format out of AE. And yes, you will have FCP re compress the final, but that's the workflow for best results.

I should probably add that this is a fine reason why you always should capture XDcam footage as ProRes 422 in Final Cut Pro, and edit in a ProRes 422 FCP timeline.

Assuming you run FCP and AE on the same machine, you can render in AE using the ProRes 422 codec. If you do, going from FCP to AE and back to FCP will be blissfully uneventful.

is there an easy way to capture xdcam ex (ex1/3) footage in proRes? i was just looking in the xdcam transfer utility and it doesn't seem like there is a way to change codec while importing. Can you do this in the log and transfer?? or is it something ill have to batch re-render in mpeg streamclip or compressor??

I don't ever mess with XDcam footage. I don't know. Why don't you search for the answer in the FCP forum?
