Quick Overview

Retime compositions using split layer markers + Marker manager
AE CC 2019 ready!

NOTICE: Version 1.3 is now available! If you've already used Marker Remap on a project, this is fully backwards compatible. v1.3 is another huge update! Check out the Changelog tab for all the new features. Since I've added so much more functionality, I've revamped the UI for clarity and consistency. You'll love the new flags (Ping-pong, Easing) as well as the powerful new Range feature (great for charts and infographics when you need to reuse the same sequences at different timings). Even if you're not in the habit of time remapping, Marker Remap is indispensable in quickly moving large marker sets around and between layers. Explore the UI below.

With the release of After Effects CC 2019 (16.0), Marker Remap is getting some competition in the form of the new built in Responsive Design feature. See how it stacks up below!

Marker Remap lets you retime compositions using split layer markers in two easy steps!

First, add timeline markers, split around key actions in the composition you’d like to retime.

Once placed into a parent comp and selected, simply click ENABLE RETIMING and... that’s it!

Adjust, delete, rearrange or retime correspondingly-named layer markers.

Here's what a Marker Remap setup looks like:

Marker Remap process demo

It's two tools in one: Time Remapper and Marker Manager

  • Extract all or some comp markers
  • Copy and paste entire marker sets across layers and comps
  • Shift markers for easy timing edits
  • Cut, paste or delete select markers or entire marker ranges to other parts of a layer

Marker Remap will change the way you work:

  • Reuse pre-comps at entirely different timings
  • Easily frame-hold pre-comp segments
  • Trigger pre-comp sequences in any order
  • Add flags to marker names to time reverse or loop marker segments
  • Retime complex sequences that would take hours to retime manually
    or that are confusing to keep track of with native time remapping keyframes
    or time stretching workflows
School of Motion"Marker Remap is a very clever tool from aescripts + aeplugins that lets you retime your animations using markers. It’s actually much cooler than it sounds, promise :) - hat tip to DJ K-Leb"

Marker Remap UI


  1. Place “Marker Remap.jsxbin” inside AfterEffects/Scripts/ScriptUI Panels
  2. Place “AddMarker.jsxbin” inside AfterEffects/Scripts/ (Advanced, not required)
  3. Restart After Effects
  4. Open the panel under Windows > Marker Remap


Marker Remap is very easy to use and is very stable. You can use AE's built in tools for adding markers, but using the Marker Remap Panel makes adding markers easy and controllable.

STEP 1: Add markers to the timeline of a comp, split around key actions.

To add timeline makers, make sure nothing is selected, and click ADD MARKER

STEP 2: Place that comp inside of another comp. Select it and click "ENABLE RETIMING”

Time Remapping gets enabled and code is added to the expression field.

STEP 3: Adjust pre-comp's layer markers to retime segments

Simply drag the markers' in and out points and you're done! Those segments have been retimed. You can use the Marker Remap panel to repeat segments, or further modify the way the markers behave by adding behavior or easing flags.

Marker Remap UI

As a rule, if nothing is selected, buttons will act on the comp's timeline. If a layer is selected, buttons will act on that layer.

Will Marker Remap functionality still work if my file is opened on a system that doesn't have Marker Remap installed?

Yes! All expressions will remain in layers that have had ENABLE RETIMING enabled. The Marker Remap panel is there to speed up the setup process. But after that, everything's set.

Why is my layer not remapping according to the split layer markers?

This could be due to one of several reasons:

  • You haven't clicked ENABLE RETIMING on the layer in question
  • Your pre-comp doesn't have corresponding timeline markers. Go into that comp and set them on the timeline.
  • You have a new version of Marker Remap but an older version of the retiming code on your layer. Simply select the layer, and click ENABLE RETIMINGagain. The latest code will be applied. (Starting in v1.1, the Time Remapping expression code will state what version of code is applied to that layer. Always make sure that the version of the expression code matches the version number of your Marker Remap installation.)
  • Another script or plug-in is also trying to control Time Remapping for that layer. In this case, you may not be able to use Marker Remap for that particular layer.

Does Marker Remap work in tandem with the new Responsive Design feature in AE CC 2019? How does it compare?

Marker Remap will not break with compositions that have markers with "Protected Regions" enabled. AE's Responsive Design doesn't interfere with Time Remapping since it uses the Time Stretch feature to stretch and protect the timing of nested pre-comps. That being said, it's counterintuitive to use both since they are accomplishing similar ends and will get in the way of each other. As of this moment, there are some limitations to Responsive Design that Marker Remap solves:

  • When managing a pre-comp in a parent comp, you can't move or retime layer markers that have been set as a Protected Region (they lose their handles). By default, Marker Remap protects marker spans simply by being able to set them to durations equivalent to their counterparts inside the pre-comp (and they remain re-timeable!)
  • When managing a pre-comp in a parent comp, Protected Regions can't be modified with powerful flags that change their behavior (loop, reverse, ping-pong, range)
  • When managing a pre-comp in a parent comp, Protected Regions can't be repeated as you can using Marker Remap
  • Responsive Design did not bring an amazing marker management panel like Marker Remap! we're still claiming a victory on this round... ha! Thanks for supporting!

What features are in the works?

  • Colorize Marker Remap markers (Waiting for Adobe to provide access to this on the backend. As of right now it can only be done manually through the interface.)
  • More easing variations (quad, quint, etc)
  • "FILL" command: fits the current marker to fill the space between the previous and next markers. Good for making sure markers butt up against each other perfectly.
  • "BUMPER MODE" flag: if this flag is present, then the space between this and the next marker (in the original timeline) will retime automatically, fully simulating the behavior of AE's default Protected Regions (but with all the advantages of Marker Remap's ability to move and retime existing marker ranges). More visual explanations to come!

And we're eager to hear what you think Marker Remap needs for your workflow!

Credit where credit is due...

The core concepts of Marker Remap come from Joe Clay's excellent iteration of Dan Ebbert's excellent implementation of marker-based remapping. Go check them out if you're into the nitty gritty of it all! Marker Remap adds setup automation, flags, time-reversing, loops and marker management to the mix in a way that makes this method easy to access and manage when you need it. I hope you find it as helpful as I have!
