Hello Chris,
My comp in AE and my sequence in Premiere have the same framerate (25 f/s).
Files are interpreted the same way.
Dynamic effect only in Premiere. (tried without, still the same).
I am using dynamic link with my audio sequence because my project in AE is a full animation with character and lips-sync, when i need to adjust my audio on my animation i don’t need to make an .wav export for each modification or cut, what i found is very usefull with this method, which was working very well before i updated.
