Bedeviling Keyframe Glitch

Posted by Robert Buncher on April 29, 2009 at 2:17 am

I posted about this problem a week or so ago. It has now returned.

I think this is some glitch, perhaps OS related or something in AE. I have been slowly color correcting this project for the last several hours and everything has been working just fine. I change a value and a keyframe is make and the image on the screen corresponds to that change.

Now suddenly if I change a keyframe all of rest of the timeline takes on the value of the one changed keyframe. If I move to another keyframe and just slightly change it (I just have to tweak it slightly, one tenth or hundredth) and image jumps to the original values of that keyframe and all the images on the timeline adopt the same values, disregarding their own keyframed values. However the values of the keyframes read as before, it is that just the images have no correct relation to their keyframe values.

For example: On one part of the timeline the image is too dark so I move the RGB Master Gamma from 1.03 to 1.20 and the image is now where I want it. But now all the rest of the timeline has increased in value even though there many other keyframes and their numerical values have not changed.

There is a disconnect between the image and the various keyframes. Now, if I go to another keyframe where the image is now very over bright but the keyframe states it is at .86 and I tweak it to .87, it drops to the correct dark value. However all the rest of the timeline is now very dark, WITHOUT THE KEYFRAMES CHANGING NUMERICAL VALUE.

I am trying to explain this clearly but it is so frustrating and difficult to explain. This is a personal project that I have been working on for over a year. I just need to get the last bit of editing and CC work done and I can mix the audio and be done. This keyframe issue is stalling the entire process.

I am working in the simplified interface of Color Finesse. I have hundreds of keyframes in this project.

This has just started to happen in the last week or so after working on this project, on and off, for months.

Is this at all clear?

Any idea as to what is happening?

I am using CS3 on a mac book pro.

Thanks

Thinking more about this I realize that it began to happen after the only time my macbook pro crashed.

What happened was that I was in the full Color Finesse interface, reading the help files to better use that program, and tried to save a look as a preset. I hit a couple keystrokes, I forget exactly perhaps shift and F2, and the screen went black, the mac shut off. I rebooted and went on. (These strokes don’t work for a laptop with out reprograming the keys)

Because of that crash, perhaps some file in AE became corrupt and only causes a problem after working for several hours.

If this is the case, what should I do. Trash preferences, reinstall AE? I am loath to reinstall AE this far along in a project. Perhaps I should clone the system drive before reinstalling AE?

Any thoughts as to if this could be the problem and the solution or otherwise.

Thanks,
Bob
