Hi everyone, I apologise in advance if this has already been covered in another thread. I had a good look around and while some discussions were hinting at this, none covered the specific problem that I have.
Initially I had the same problem as a few people have had - when I right clicked clips in my Premiere timeline and selected "Replace with After Effects composition", I was confused and annoyed as to why my transitions no longer worked in Premiere. I now understand that it's to do with handles (the parts of a clip before the in and after the out points that allow you to do things like cross dissolves right?) and the fact that dynamically linked AE clips don't automatically account for them. The original clip is long enough to deal with transitions but my dynamically linked clip starts and stops at the in/out points, not leaving me enough spare frames to cross dissolve.
Okay, so finally my question. Is there a simple way, when dynamic linking, to make AE account for handles? That is, to make it use enough of the original clips, to give it enough on either side of my in/out points that I can still cross dissolve?
I'd appreciate any help with this.
Not that I am aware of. There are work arounds like adding a little more to the head of the clip in the AE DL comp and extend the comps duration the same amount . I did this all the time when I used Auto Duck with FCP to send clips to AE. I havent tried it with dynamic links yet but it should theoretically work.
Since your clip you want to replace with AE composition may be quite complex piece of several nested sequences, and you are not prohibited from having some extra video and audio tracks in the timeline, it's a easier to do some preparatory work right in PrPro:
1. Select you clip you want to replace with AE composition and paste it e.g. into the tracks above and below
2. Expand it according to your transitions borders and then replace with AE comp
3. When you finish your magic in AE, select that very clip in the PrPro timeline you originally wanted to replace with AE comp (if you want to keep your original audio untouched, unlink audio from video first).
4. Select your Dynamically Linked comp in your Project panel or Source monitor, keep Alt/Opt pressing and drag it over selected clip in the timeline - it preserves your transitions from disappearing (if you want to perlace just video, drag only video from Source monitor accordingly)
Thanks for the workaround.
For whatever reason, the trick of Option-Dragging (iMac) the composition back onto the original clip on the timeline in order to preserve the transition does not seem to work after the first time, at least in my hands. What happens is that the composition overwrites the clip AND the transition. It is not a big deal, as I can then just reapply the transitions and things look fine, but I wonder whether somebody has noticed that too, or whether I am just doing something wrong.
Sorry, I did not have a chance to try that until now...
I still don't get it. If I Alt-Drag the linked composition over the original clip, I loose the handles (the composition overwrite them, including of course the part of the clips before and after).
If I Shift+Alt-Drag, nothing happens...
I think I have managed to do that once, so it is quite puzzling.
I am using PP 5.5.2, AE 10.5 on Mac OS Lion.
EDIT: nevermind, I figured out that I was not reading the instructions properly, dragging the clip that I had dragged one track above (and replaced by a composition) onto the original track. Dragging the Linked Composition FROM THE PROJECT EXPLORER of course does the job.
I've got a follow-up question regarding this technique. I am still a bit confused about what is "linked" or not.
Namely, what I usually do is transcode my footage to a codec and bitrate that is manageable for my system and edit that transcoded footage.
Then, after I am satisfied with the sequence (having color corrected, titled, etc), I use "replace footage..." to replace all the transcoded clips by their originals and export the sequence to its final destination, hopefully recovering the original footage quality.
My question is whether this will also work for linked compositions. That is, supposed that I stabilized a (transcoded) clip and reinsert it in the timeline as discussed in this thread. If I replace that clip in the Project Explorer by the original (using "replace footage..."), will the dynamic link work with the new (original) clip? I guess I could experiment and delete the transcoded footage after I have done the replacement to see whether that breaks the sequence...
I hope my question makes sense to someone.
No, that will not work this way.
When you replace a clip with After Effects composition, After Effects imports your transcoded clip(s) as an assets for that Dynamically Linked composition into AE project, which is completely 'independent'. So as to achieve the result you want you should replace your transcoded clip(s) with original footage(s) in AE project as well.
The technique works in preserving the transitions but doesn’t let ALL the effects in AE come through.
For example if you color correct in Ae that works fine with this technique, but if you use warp stabilizer the stabilization is not carried through to premier and the linked comp is left unstabilized... very strange ?? any ideas why or how to get warp stabilizer to work and preserve the transitions ?
Shouldn't be true in general. PrPro does transfer all effects applied within dynamically linked AE composition, including Warp Stabilizer.
You may probably encounter two issues:
- the necessity to render Entire Work Area (not just Effects in Work Area);
- while playing back a transition applied on the left handle of the dynamically linked AE comp with Warp Stabilizer PrPro 'freezes' initial frames until it reaches the cut between clips.
The first one is a 'feature', the second one in my humble opinion is a 'bug'. Use Slip Tool to correct it.
I couldn't get it to work. I could slip one way but not the other and after slipping in one direction, there was a gap at the end (during the transition), so a black flash occured. I resorted to recreating the comp...but even then, after reprocessing the clip, I got the same bug. :-(
Sounds like you are trying to shift frames of your dynamically linked comp with Slip Tool too much.
Lets explore the following example.
Your timeline contains three clips, each which 5 seconds length.
You applied transitions on cuts. Each transition length is 2 seconds, center at cut.
You decided to replace the clip in the middle with dynamically linked AE composition.
In our case you need to extend targeted clip 1 second left and 1 second right to get handles which provide smooth 2 second transitions with center at cut. Therefore you get 7 seconds clip to replace with AE composition.
When you finish your magic in After Effects and try to drag and drop dynamically linked comp over your clip in PrPro timeline, PrPro may shift the beginning of the resulting clip by its first cut on the timeline. I.e. your resulting clip first frame is now situated at cut instead of 1 second prior to cut as it should be.
All you need to correct the issue is to shift frames with Slip Tool exactly 1 second left.
Gotcha! It works but that's odd. PP basically did not handle the handle properly and "filled" in the first transition's last half with the first frame of the clip/comp intended for the handle (static display) and then resumed playing the clip. I suppose it therefore had extra footage at the end of the clip for the end transition?
Thanks a bunch for guiding me through it.
You said it's a reported bug? It is not systematic for all linked comps in which the warp stabilizer is used, as I have many others in my sequence, and they seem to play fine.
I suppose it therefore had extra footage at the end of the clip for the end transition?Yes. PrPro doesn't change the length of your dynamically linked comp. In the example above it's still 7 seconds.
Since the first frame is now located at cut instead of 1 second prior to cut, the last frame is located 2 seconds after the second cut instead of 1 second after the second cut.
'Freezing' first frame at the beginning of first transition behaviour is similar to one when you apply a transition onto ordinary clips which don't have extra frames for handles (e.g. clip physically starts at cut; when you apply a transition on that clip which ends at cut or centered at cut, you get the following PrPro warning: 'Insufficient media. This transition will contain repeated frames')
You said it's a reported bug?It's up to you to decide whether to file bug report or not...
Wow! I took a closer look at my sequence and it turns out that ALL transitions involving linked comps (mine are mostly used to apply the warp stabilizer) are messed up... I should have reacted earlier, as the transitions looked half hatched on the sequence. But I am new to PP, so I didn't quite know what to do of this info.
Definitely worth a bug report now that the reproducibility is guaranteed! I'll do that once I have fixed my sequence...
