AE CC Keyframes for color correction not EZ anything

Could use a little assistance please! Is there something I'm missing here? When I was using the previous version of AE (6.5?) I could easily set keyframes for interpolated parameters changing over time. I wasn't good at it, but with enough trial and error (and some non-family-friendly verbiage) I could coerce the program to do what I wanted.

I have a fairly simple situation here, and I just discovered that the keyframe thing is different. For some reason, there is no change over time from (Example: Brightness +0.03 to -1 over 15 seconds) both keyframes are set relationship EZ Ease out - In, messed with the graph editor, etc, HOWEVER, there is no change until the frame of the keyframe, then POW! Sudden change.

This will not do!

Please advise!

Do you have a decent grasp on the different styles of interpolation of key frames? (not meaning that to sound bad) Also you could have messed up the curve some how, try clicking the key frame stop watch off and re-doing what you want it to do. Also try a more drastic change so you can see what exactly is happening if you can't already. Sounds like you can though.

Graph editors can be a bit touchy some times, also I have just overloaded AE and gotten off weird results for no real reason. Shut down restart the machine if you have not in a long time. It's rare but it does happen.

I think what you might want is an ease in ease out right style right? So the curve goes from a low point and has a gradual slope to a peak and a gradual slope down. The Key frame assistant and the interpolation are two different things, right clicking your key frame (a brand new one) and setting it to bezier in the key frame interpolation might give you the results your looking for.

If none of that works one way to better see what a particular thing is doing, is to apply it to a movement of a shape. Make a simple solid with a scale of 10, then play with the different styles of interpolation with movement in one direction. That's one of the easiest ways to see the actual effect of that type of thing. Doing it on brightness it's a bit tricky to see what one verses the other does.

A common mistake among people that due looping animations is not setting it to linear, because when your set at Bezier or ease in ease out is you get a slow to fast to slow look instead of a continual speed. The peaking looks weird, like a ball going from slow to fast, slow to fast...

Was a little rushed to write this feel free to PM me if you need any more help.

Thinking about this more, did you accidentally put a key frame almost directly on top of another? Pull your time slider top gray track above the numbers of frames in on each side and get the chunk of time your working on to just showing the small maybe 50-100 frames or less of what your working on to make sure there isn't a key frame that got put a frame before it. When your working with hundreds or thousands of frames or on time code it can be really easy to have a key frame sitting right before the other one and not notice. That could easily be the cause of your pop.

Thanks Bryan - the situation resolved itself, and dangit, I don't remember how.....that's the thing, while I've seen some of the situations you described happen, this was one of those cases where was a very simple 2 keyframe situation (after I broke it all down and started over). But suddenly it started working! I don't remember if I restarted or not before that - it just started doing what I expected it to do, and I got the clip done. Could have been the equivalent of a total crash in Sony Vegas, except that AE just soldiers on and pretends nothing is wrong.

It's rare, but AE will so weird stuff from time to time. Usually it's a 100% crash out of the blue, too much footage, too many effects, then sudden death. Glad it got worked out for you though.

I just experienced the same weirdness on a clip a couple of days ago. I simply shut down AE and restarted. That cleared it up. I think the auto levels, auto colors, and auto contrast and brightness are the issue. I was just experimenting to se what or how well these function in cc... They suck. :) i really have never used auto anything. Now i know why.

Did a clip yesterday with a gentle adjustment over time to compensate for light falloff during a tilt. Worked like a charm. Used the same method as I mentioned in the original post, but this time it worked great. Musta been a glitch before.

Agreed - "Auto" might as well be "FUBAR"
