    I don’t use hold keyframes much, but in this case it’s the easiest thing to do.

    I’m doing a couple moves on a precomp. It’s a big layer with a grid of stills. I want it to pan across, then cut to zooming in, then cut to panning another direction, etc. I could split the layer and do this with multiple layers like a video edit, but in this case, I have a lot of parenting to this particular layer going on so splitting it up gets messy.

    What is happening, is I’m doing all the moves with linear keyframes. The second keyframe being a HOLD keyframe. The frame after that keyframe is a new linear keyframe in a completely new position. Trying to accomplish a cut between the two. But that 3rd keyframe is sort of a morph of the hold keyframe before it, and itself. Half transparent if you will. I get goofy stuff like this with keyframes as I play around , and usually have to go into graph mode or manually change the interpolation. But this time, everything in the graph is square corned, no handles. The interpolation settings is completely linear.

    I guess I’m forgetting something about hold keyframes or something. But seems there should be no interpolation between a hold keyframe, and a new linear keyframe place directly after it.

    I’ll try some of that. But I don’t think that’s it. If you go frame by frame here’s what I see…

    frame 312-hold keyframe: looks solid
    frame 313-linear keyframe: blended with hold keyframe
    frame 314-solid version of 313, but without the blending.
    frame 315-motion becomes apparent

    So if 314 had motion or blending I’d agree with you. Hmmmm….
