Version: 2.7   Sign up to be notified by email when a new version of this script is posted

This script converts the selected properties to expressions and adds the current value. This locks the property with this value and it ignores any keyframes. This is useful for adjusting keyframed values at a different time than they are set at. It can also enable or disable the selected expressions.

Version History

  • v2.7 Fixed foreign language compatibility with CS5.5 – Nov 2011
  • v2.6 (Aug 2010)
    • When there is an expression, the script locks the property and also stores the expression so that when unlocking the property goes back to its original state.
    • CS5 compatibility.
  • v2.5 Initial release on aescripts.com (Aug 2009)

About the author

My name is Charles Bordenave and I am currently located in France. I started working with After Effects in 2005, when I was a PhD student in computer science at Montreal. My interest quickly converged to expressions and scripting. Nowadays I'm regularly hired on a freelance basis by production studios focussed on tv broadcast, cartoon animation, motion graphics or cinema. My job usually consists of developing customized automation tools for After Effects.
