Dynamic Link has slowly gotten better and less... umm... forgetful. In my experience, it was randomly flaky in CS5 without much rationale.
Don't delete and re-import the DL'ed comp; instead, just select the offline comp footage item in the Project Panel, right-click, and select Link Media. In the dialog, navigate to your AE comp, and Pr should automatically reconnect to the proper comp.
Many thanks, i wil try that
Here's how I do it, and have never had a comp go offline.
1. Create a Premier Pro project
2. From within Premiere Pro go to File>Dynamic Link>New After Effects Comp
3. Do what you need to in AE.
4. Drop the composition onto the timeline
5. Playback, all is ok
6. Save and close
Thanks for your reply.
Would that work if I already had a composition created? or just new comps?
Just new comps.
But for those already created, for for step 2 you choose File>Dynamic Link>Import AE comp.
