I have heard over and over again since dynamic link first began that if you render a dynamically linked comp in AE, premiere pro will play back the cached version in realtime in the timeline. I have NEVER seen this happen or managed to get this to work. even if i render the AE comp and dynamically link it to prem pro it simply does not play back in realtime. i still have to render the dynamically linked comp in the prem pro timeline to see it play back in realtime. because of this i have never used dynamic link as it is just as slow and in some cases less efficient than just rendering it out on full to begin with. (the old fashioned way)
does anybody know this deep and dark secret that has evaded me for so many years?
The only time I get anything even approximating real-time playback with a DL'ed AE comp is if it's just a simple text animation with no background. I usually have to play through the clip once or twice in PPro for the frames to be cached before it'll play most of the frames back without stuttering. AE on its own doesn't have much in the way of real-time playback (RAM preview doesn't count, because it's a render), so I think it's a bit optimistic to expect DL to do the same.
The benefit of Dynamic Link is that your linked comp is live--I've never seen it billed as being real-time. This is where any sort of time savings comes into play. Your best bet is to RAM preview in AE and make sure everything looks good, and then "set it and forget it" in PPro until you're ready for final export.
ok great thanks for the info!
