    Hey guys,

    I’ve been using CC for quite some time now without a hitch. Today I’ve run into a problem I’ve never seen: I am totally unable to edit keyframes (meaning right-click and adjust keyframe interpolation, toggle keyframe hold, etc) and it is only in one particular comp. I’ve tried deleting my preferences but other than that, I can’t seem to figure out where the problem is coming from nor how to go about fixing it. Any input would be greatly appreciated!

    Also, I should add that I tried creating a new comp and copying and pasting the layers into it, but when I select all of the layers i get an error saying:

    After Effects can’t continue: an input contract violation has occurred

    Thoughts?

    Did you inadvertently lock the layer with keyframes?

    That message is typically because of a badly written third-party plug-in. Are you using any third-party effects in this composition?

    The only 3rd party plugin used is Particular, which is precomped and turned off. Also nothing is locked. I also forgot to mention that I can’t select any keyframes directly by clicking, I have to drag select them. And even then, I can’t move them or make any modifications. I can however access all keyframe interpolation controls through the Animation menu but just not directly. On the other hand, when I add new layers to the comp I can adjust the keyframes however I want with no problems.

    As Todd’s suggested, it’s very likely a plugin issue. What are the effects you’ve applied to the problem layers?

    Were the keyframes created in a composition that then had its framerate changed?

    I ran into the same problem and I realized that it is due to framerate change.

    I had a text layer in a 25fps comp which was a subtitle for a feature film.

    Then the client requested a 24fps version of the subtitle for cinema premiere so I copied the text layer from 25fps comp to a new 24fps one.

    At first I didn’t have any problems, but later on, when I arrived at around 45 min, the mentioned problem happend.

    Solution:
    The solution is simple. Just create your layer from scratch in a comp with a correct framerate (In my case, a text layer in a 24fps comp), then copy the attributes (Effects and Keyframes) from the one which is locked to the new one and then replace the new one with the old one.
