Here’s a quick script to create comp markers at regular intervals as follows:

Regularly-spaced comp markers

When you run keen-CompMarkersMake, it will open a dialog box asking you how often it should create comp markers. The default interval is every 12 frames.

Three major points to keep in mind:

  1. The marker interval is measured in frames.
  2. The marker interval will begin at the current time in the comp. In other words, the first marker will be placed at the current-time indicator (CTI).
  3. Marker creation will be limited to the work area.

To run, download and unzip this script. You may place it in your After Effects script folder (or drag it into your project with Ae CC 12.1 and higher), restart Ae and run it from the File > Scripts menu, or you may run it from anywhere via File > Scripts > Run script file…

If you have a lot of track matte layers and want to manage their selection, or if you want to precompose the matte and fill layers, here’s keen-UncleMatte:


Selection and precomposing should work as advertised, but if you run across any issues, please do let me know and I’ll try to sort them out.

Unzip the script and place in your After Effects ScriptUI folder, then invoke from the Window menu.

keen-UnUnMult: A workaround for the UnMult bug in Ae 13.1 (CC 2014.1)

The CC 2014.1 release of After Effects (version 13.1) has a nasty bug which causes the application to fail on effects with no properties, like the popular Red Giant Software’s UnMult effect [link], with a never-ending barrage of error message windows:

After Effects error: internal verification failure, sorry ! {unexpected match name searched for in group} ( 29 :: 0 )

After Effects error: internal verification failure, sorry ! {unexpected match name searched for in group} ( 29 :: 0 )

The Ae team is working on a fix [link], and it should be out soon, but in the meantime, I’ve developed a workaround.

I’ve written a script, keen-UnUnMult, which searches a project file for any instance of UnMult and replaces it with one of three unmultiplication alternatives:


Each UnMult alternative has pros and cons. Channel Combiner plus Remove Color Matte is a good match for the look of UnMult, but is limited to 8bpc. Set Matte plus Remove Color Matte works at 8-, 16- or 32bpc, but is not mathematically or visually identical to UnMult results. Video Copilot’s free Vibrance effect [link] can do unmultiplication, but it’s third-party and produces slightly different results.

None of these replacements may be perfect, but if you are having trouble opening and using an older project with the current 13.1 release of After Effects, this script may be able to help you.

You can download the script below. Unzip and drag the keen-UnUnMult-v1x3.jsxbin file into your ScriptUI folder:
PC: C:\Program Files\Adobe\After Effects CC 2014\Support Files\Scripts\ScriptUI Panels
Mac: /Applications/Adobe After Effects 2014/Scripts/ScriptUI Panels

If your UnMult project crashes immediately upon opening in Ae 13.1, hold the Shift key while opening the project. This opens the project but does not open any comp viewers and should get you past the error loop. From the Window menu, select keen-UnUnMult, choose your replacement method, and click the button.

This is working nicely here, but I haven’t done exhaustive testing. Please report back any issues and I’ll try to get them fixed ASAP.

I’m taking a page from Jeff Almasol’s book here: if this gets you out of a jam, please consider making a donation to a charity that matters to you and tell us about it on Twitter with the #devforacause hashtag.

After Effects Script: keen_3dLayerTools

I previously published a script which centers and orients layers to the active camera [link].

Building on that, I’ve published a new version which also adds a tool for promoting 2D layers to 3D in the active camera’s view, keeping the apparent 2D positioning.

Unzip the script and drop it in your ScriptUI folder. Relaunch After Effects, then open it from the Window menu

Suppress After Effects save-on-crash

After Effects has a very useful feature wherein it attempts to save your project if it detects a crash. However, in certain cases where you’re really pushing the envelope or trying to troubleshoot a problem, this may not be desirable behavior [link].

Here’s a quick script which lets you toggle this save-on-crash behavior. It’s just a simple checkbox to turn it on and off:

To install, unzip this and install the .jsxbin file into your ScriptUI folder [link].

To use after installation, click the Window menu and choose keen_ToggleCrashSave to open the panel.
