NEW TUTORIAL: Trim Compose Script

Today we have a new After Effects script to help you work with shots on a large VFX project like a Commercial or a music video that has many edits. One of the nice things about doing VFX inside of AE is seeing your shots in sequence to make sure they flow together, but it can get tricky if you start adding hundreds of layers into a single composition as we all know.

A more organized solution is to Pre-Compose each shot into individual compositions and do the work inside. The Trim Compose Script helps make that job fast and easy but wait there’s more. The script automatically takes selected layers and then pre-composes each one into time accurate pre-comps, based on the length of each edit.


  • Create edit accurate pre-comps based on final cut
  • Keeps projects organized and VFX inside individual comps
  • Create proxies for specific range based on the edit
  • Batch process shots to work with multiple artists
  • Adds frame handles automatically

This probably doesn’t make any sense, check out the video for a full demonstration.

I'm Sorry Shape Layers! I love you!
I must confess… I was never a big fan of shape layers…  we just didn’t get along.  I was used to using masks but suddenly (around AE CS3) the same mask tool began creating Red vector shapes. At first, they seemed cool enough but after accidentally adding shape layers to my comps, instead of masks, I lashed […]

Destruction Experiment!
What is this thing! I’ve basically combined a bunch of stuff into one experiment! I might have been inspired by the amazing planet explosions from The Force Awakens but wanted to see if I could get a cool version inside Element 3D. Few Notes on this experiment; I added smoke elements, shockwaves using CC Sphere, and even […]

Great one and a big time saver, thanx alot!

I got an question regarding this workflow. Say I cut my video in premiere and do the post in AE like you shown in this tut. As far as the cut doesn't change your fine and render the final movie out of AE.

But what happens if you have to change some things in the cut after you did the post? I find no solution, cause the dynamic link only works in one direction:-/

The only thing you could do is copy the new cut out of premiere to AE and copy/paste the adjustments from the post before, which is annoying.

Does anyone has a good solution for that?

Great tutorial and script! Thank you. I use FCP almost exclusively and don't have a ton of experience with premiere and dynamic link but will pull my FCP timeline into Premiere just to get it into AE w/o using Automatic Duck. However, it would be nice to be able to go back and forth seamlessly. I was always wondering what the best approach was for organizing everything with a longer video. I guess I was doing it right but definitely learned some new tips. Anyways, thanks agin.

This seems like a strange workflow. Dynamic link is built-in and does exactly this without the hassle. Just finished a color timing job using pr+ae no problem.

Yea, this is awesome. One of those to who did this manually for an extremely complex scene. I wonder though, is there a reason you did NOT use Dynamic linking? I have not tried using the script with it but just curious to know. Best!

I really wish you'd invented this a month ago! I have a complex scene from a film I'm making, and this would have saved me a lot of time in keeping nice and organised!

However, this is a great tool for just the everyday stuff. Even for just one shot. A couple of clicks instead of resizing and replacing. Great script, thanks a lot for keeping a lot of these great tools free and creating them from and actual need you've come across rather than to just create something.

This and the copy/paste frame are HUGE time savers.

For all FCP users you can use the free script here to use just like the copy and paste feature in Premiere. All you have to do is save your XML file and then open that XML final using the script.

It\'s great

Are there any reasons why you didn't use the actual Dynamic Link function via right click replace with afx composition?
    6 years ago
    That's exactly what I though when I first saw the tutorial! I think you can do exactly the same thing Dynamic Link function in the Premier Pro.
    6 years ago
    I was also thinking why not...
    6 years ago
    i tried the dynamic method well too much. but it always slowed down my computer. so i tried one day to go the same way as andrew, only difference i import my prproj file direct in aex. i got all my clips in one composition and not one composition per clip. and work at full performance.
