Activity Forums Adobe After Effects Expressions Camera Movement

  • Posted by Ollie Wainwright on November 7, 2007 at 5:03 pm

    are there any expressions that can create random motion of a 35mm camera around its pivot point in after effects?

    i am fairly new to how to create smooth natural camera movement within a composition and was wondering if anyone maybe knew of a website that lists different movement expressions that you can just copy and paste over from web to after effects.

    hopefully i will soon be able to do this without the help from others but at the minute i am still a novice!!!!!!

    cheers for taking the time to read this and thanks for any type of reply.

    Rotating a camera around its pivot is fairly simple with a wiggle() expression applied to the camera’s orientation property. However, for this to work you need to turn off the camera’s auto-orient to point of interest by right clicking on the Camera layer and going to Transform > Auto-Orient > Off.

    Then apply this to the orientation property:

    f = 3;
    a = 1;
    wiggle(f,a);

    You can change the frequency (f) for a different feel, lower it for more of a ‘floating camera’ feel or raise it for a more frenetic ‘handheld’ feel. The amplitude (a) should probably remain quite low as the Orientation is measured in degrees and only a small change in degrees is very noticeable.

    There are some pretty cool camera expressions out there, some of them developed by Dan Ebberts and I believe available on his website: https://www.motionscript.com
