Time remapping and replace with AE composition problem with time matching

Adobe, please fix this annoying problem that is going for a long time from one verstion to another.

For example, I'm making time remapping in Premiere clip. Then I want to add more complicated effects and do replace with AE comptosition command. Ok, now I have this clip in AE with time remapping there. But if I compare original frames in Premiere with what I have in AE, then I see some time shift. It's a small shift, may be just 1-2-3 frames but I see this problem for many times. Some clips with fast motion need to be very accurate, so I just can't say "no problem" to this small shift. So I have to go to AE and then carefully try to find what I need to change in time remapping there to get look like it was in Premiere.

Replace with AE composition is a very good tool, but I just can't trust it. In some cases (like this) it just changing the look of my clip.

P.S. Also similar problem with optical flow interpolation. If I make replace with AE composition then this effect is just turning off. And in AE I manually have to make similar settings again. I can't belive that this can't be solved for so long time.

Yeah, I get how annoying that is. "Replace with AE Composition" can mess up time shifts and optical flow settings, which is a big problem when you need things precise. Having to redo everything manually in AE just adds to the frustration. Hopefully, Adobe will fix this bug soon since it's been a problem for a while.

There is no bug present but I get the frustration. You have to understand that the mechanisms designed in Premiere to do speed changes is different from that of After Effects'. Because of this you wouldn't be able to get a perfect frame match due to precision differences and animation curves.

If you need an absolute match the best approach would be to not have the timeremapping in AE at all. We sometimes nest footage in a native source clip resolution sequence and apply timeremapping outside of it. Then we can also place that source clip in AE to do compositing and whatever else and have it render back to Premiere inside that nest. Because it's still in the nest, the timeremap of Premiere remains there outside the nest. For the context of compositing it is also a very bad idea to work on timeremapped frames anyway.

I would understand that if you need to do totally different things to the material, maybe more motion design related then it's not always the best approach. In those cases I would try to match the data in AE's timeremap.

How do I fix this issue after using dynamic link (automatic time remapping shift)?? Am I supposed to redo the time remapping in After Effects? Or do I cut off the couple of unnecessary frames??

Hi @SPfoto,

That's it mate. Replace with AE (dynamic link) is GREAT. Sadly, dynamic link has not worked for me as well. The workaround is to be precise with what you need, and shift the AE work towards the end of your workflow. This was annoying at first, but it forced me to be more organised and precise. And believe me it was a game changer, because BEFORE I even open AE, I know, almost precisely, what I need to do in AE. Massive time saver.

Sorry for ressponding so late, but hope it can be of some help.

Cheers,

Yash

I'm having the same problem for as long as I can remember, this is really annoying. Premiere and After Effects should have the exact same way to deal with time. I hope one day we can just edit flowlessly in a combined after effects/premiere without having to endure all these archaic bugs. Please Adobe, set your priorities.
