Forums Adobe After Effects Macro? Automating repetitive tasks??

  • Macro? Automating repetitive tasks??

  • Joseph M. Morgan

    I do quite a bit work turning still photos into movies. I use After-Effects to do some small things like create a little movement, and use the adjust->auto color effect. I need some help automating most of the repetitive work.

    For example, for every photo I:

    1) Create a comp with a similar name to the photo, such as: Mary.JPG (photo name) = MaryJPG (comp name)
    2) Put the photo into the comp
    3) Add the Adjust->Auto Color effect
    4) Resize the photo to near the comp size
    5) Turn on keyframes for Position and Scale

    The composition length is always 6 seconds. After that, the scaling and position will vary according to the picture.

    Can I use expressions to do it??? Is there a better way??? How can I speed up this kind of thing???

    Hey,

    Scripting!

    Check this stuff out, once you get your head around it you’ll be up and running in no time…

    Take care,

    Oh my god… it’s JavaScript! I’ll be right at home (20yr programming veteran)…. thanks a million!

    And… I looked at the AEEnhancers site… and there is a script there I can probably just modify to do what I need…

    Hopefully there will be a relatively good object model reference out there..

    Thanks again…

    If you wanted to share any new scripts, here or at aenchancers, that would be great.

    Hey,

    That’s AWESOME; you’ll probably pick it up in no time. Here’s a link to Adobe’s scripting reference, it’s not easy for a beginner but for someone with some programming experience it probably won’t be too much hassle.

    https://pages.emerson.edu/departments/infotech/web/helpdesk/documentation/2004/aftereffects65/ScriptingGuide.pdf

    There’s a couple of members at the forum here who know an awful lot about scripting, virtually all my questions have been answered : )

    Take care,

    Nick

    Will do… call me lazy… but I became a programmer 20 years ago because I didn’t want to keep doing the same thing over and over again….

    I’ll dig into this right away… and keep everyone up to date.

    OK…. I finally got to the point I could write this thing… it is a modification of “COMPIFY” from the AE Enhancers web site. However, I made quite a few modifications… most notably:

    1) Added much more white space to make the code easier for ME to read
    2) Changed variable names for more meaningful names for ME.
    3) Added a list of existing folders from which to choose to place the new comps
    4) Added a comp size option
    5) Scaled the still images to as close to the comp scale as possible.
    6) Added some utility functions to simplify making the UI containers so they
    made more sense to ME… that is, ( x, y, width, height ) rather than by using
    the bounds ( left, top, right, bottom ). It also eases the understanding that
    the controls are set relative to the container.

    After I post here, I am going to do some refactoring so the script isn’t so long….
