Dynamic Link to AE and timewarp has funky results

[Alex Udell]

“Aha, I’ve got it working now. It appears the problem before was that I was opening the new comp and editing that one, not just continuing to edit on the same one.”

Yup…

it’s hard to write that w/o it getting a bit convoluted.

Glad you got it sorted!

Hey Ryan ,
I am facing same issue and not able to rectify it. could u please elaborate what you actually did to resolve it.

Thanks in advance.

Vipul, there were two different solutions that both worked for me. I chose option 1.

1) After dual linking, in AE, select pre-compose composition, then apply timewarp to the ORIGINAL comp (not the new one that pops up when you pre-compose).

2) A bit more roundabout, but you could also split the clip in PP, render out just that section of the clip, take it into AE and apply the timewarp, and then copy the timeline from AE back into PP.

Thanks a lot for replying ryan.
option 1 worked for me too.

Wondering the reason for this though.

[Alex Udell]

because even though you have trimmed a clip to your timeline in Premiere Pro, it’s still referencing your originally ingested media clip.

So even if your edit is only 5 seconds long, the underlying media file may be 5 minutes long.

so Time warping may take place from zero based on the file, not on your edited clip…

by precomping….you place constraints on what frames are accessible to time warp, this gives you a more predictable result.

Thanx for replying alex. that solves my dilemma.
So, is this as per design or a product limitation.?

[Alex Udell]

I wouldn’t say it’s a limitation….

I think it’s a question of understanding the underlying design of the software….

Better to be unconstrained and have a work around, then being constrained without a solution.

My opinion….

So here’s a question. Let’s say that you had cut your clip into 100 different pieces to do the editing. Then you decide you want to adjust the color to give it a greenish hue. Normally you’d either have to apply that effect to every clip or render out and apply it to the final file and render again.

It seems like, with what we’ve learned here, you could just DL one of the cuts to AE and adjust the color there without pre-composing, and it would update all of your clips instead of just the one. Maybe that’s what they were going for.

It is a bit frustrating that there was no documentation detailing this, but in the end I think it working this way ends up being a good thing. It gives you the option of both editing the entire sequence in one fell swoop or just editing the one piece that you want to. It just would have been nice if they had told us this from the get-go 😛

Depending on the sophistication of the color correction there may not be a need to go to AE.

You might consider at the front end of a project:

1) Taking your clip, and putting it in a sequence…. then applying your look within the clip in that sequence…

2) use that sequence as the source to edit from.

In this way if you change the Color correction in the source “nest” it will change for all uses of the clip in your main edit.

so depending on what you are trying to do….this workflow can be useful….a lot better than having to search the timeline and reapply a color correction setup 100 times individually…

But…PPro also needs timeline searching like FCP and the ability to save selection sets as well….

I know this is an old post but it might help someone. Here is what I did:

I have two clips in a Premiere Pro CS6 project (m2ts) that I want to use timewarp on. I imported the project into After Effects. I increased the duration x2 (Composition/Compostion Settings/Duration); turned each clip into a PreComp (Layer/Pre-Comp/Move all attributes into the new composition). Then enabled time remapping for each clip and then added timewarp.

I found that I had to reduce the speed to 25% to get 50% (sometimes) but it worked. It still needed fiddling i.e. drag the end of the clips to the desired length but I got the darn thing to work.

When working on 2+ clips in a project I found that after the first clip, when I added Timewarp, I get a black screen. What happened is that the scene went massively to the right in the time line. What I did here was to find where the clip ended in the time line and compress the time line to the clip size (grab the very end of the time line and drag it left or right). Then set the warp to 100 and then decrease it by 5. At each decrease I would have to drag the right end of the time line out. I would repeat this process until I got to 50.
