So I am working multiple projects right now, primarily on a single machine, but had to render out some 30 minute very complicated projects in Adobe Media Encorder, and I have found it is very unstable with the long complicated projects, so we copied the media to an alternate drive and I moved to another machine. Premiere Pro easily relinked my whole project in a few seconds, but with after effects it was not so easy.
I had quite a few After Effects compositions that I had sent from Premiere Pro, and the problem arose from the fact that the media are MXF files from a P2 card. Normally in after effects if you replace a single file with it’s original file, it looks and relinks all the files it can in that same structure, but this does not work with MXF files.
MXF files that were imported using Adobe Dynamic Link from Premiere pro show up without their extension in After Effects, while the actual files have the .mxf extension. If you import the same files normally in After Effects they show up fine with extension, so this is a Dynamic Link issue. And the problem is that when you replace a file with it’s correct original, it does not see the other files as the correct file because they don’t have the correct extension in After Effects.
This means that you have to manually relink the files in After Effects one at a time, which is a major time waster. I am pretty sure that this is an Adobe Dynamic Link issue, so I have reported this to adobe and hope that someday they fix this bug (you can report bugs and features requests to Adobe here).
Of course this wasn’t my only issue, as when I brought the project back to the original system after using File Synchronization to bring the projects back to the original issue, the Premiere Pro project got messed up. The timeline is completely screwed up and doesn’t show correctly.
Now I was able to work around this, by opening the earlier project in Premiere and using the Media Browser to import the new sequence into Premiere Pro. The cool part is that it also imported all the new files that I had imported into the proper places within the project. They were offline, but it was easy enough to relink the files. Still not sure what happened here, but it is furstrating!
