Activity Forums Adobe After Effects Keyframes not responding correctly

  • Keyframes not responding correctly

    There is something odd going on in the very large composition I am working on.

    This has just started to happen after working on this project, on and off, for months.

    This is difficult to explain but here goes.

    I am setting keyframes in the simplified version of Color Finesse changing the values of the red gamma and gain over the length of a clip. As I move the coursor from keyframe to keyframe the numbers change the but the actual color as viewed on the monitor does not change. It will hold the color of one of the keyframes ignoring the changes of the rest of the keyframes. However, if I just tweak one of the parameters a tiny bit the color will change to match the numbers of that keyframe and then those colors will hold as that on all keyframes even though the numerical parameters change at each keyframe.

    Is this at all clear?

    Any ideas as to what is happening?

    I am using CS3.

    Thanks,
    Bob

    Are your keyframes HOLD keyframes or one of the interpolated keyframe types? It does sound like you have Hold keyframes in place. There may also be the case that interpolating Gamma may not be allowed. See if there is something else that you can use in its place.

    I’ve noticed the same problem (After Effects CS4 Vista) – linear temporal keyframing of numerous variables on an adjustment layer (eg master saturation) yields a fixed change in video appearance that is the same as the LAST keyframe on the timeline. Scrubbing the CTI to any time doesn’t change the video appearance, even though numerical values of the keyframes variable/s can be seen to be changing during scrubbing. I don’t really want to use multiple instances of CF on separate, masked adjustment layers just to get around this glitch. Any useful suggestions?
