Did you select all of the keyframes involved before you clicked the "convert to linear" button? Your screenshot doesn't show them all as selected.
This is a no-brainer -- convert the keyframes in aquestion to "Linear" in the keyframe interpolation and the problem goes away.
If it doesn't, you have a more fundamental problem with your hardware, your OS or something else, like a third-party card in your machine.
But why sometimes I got a lines like this to help to modify my curve:
And sometimes It doesn't appear? I can't use curves in After Effects at all. It doesn't work correctly every time.
What should I do if I want to see that grey lines to modify my curve (yellow arrow on screen above)? Please, tell me. I don't know. And this is like randomize.
What are you trying to modify? The way these lines react to modifications depend on the property. We don't know anything at all about what you're trying to accomplish because you haven't shown us the timeline or the properties you're trying to change.
It took me a little while to learn how to use the graph editor, but it is 100% predictable once you figure it out.
If you are trying to convert the path that your object takes when animating positio then the best place to do that is in the composition window.
If Y and X are moving in a non-linear fashion and you want Z to move in a linear path and you want to edit that path in the graph editor try pressing the G key to bring up the pen tool. I think that maybe it is time for me to think about a graph editor tutorial. The ones I have seen on the Internet are not very comprehensive.
Hi Rick, thanks for your answer.
You know, everything in that menu is different. A graph editor is like a new thing to learn.
For example: why they changed Y dimensions? When I apply a minus-values it is goes UP, and when I apply plus-values everything goes DOWN. So dimensions are completely different. Even our curves don't "grow up". I see every curve is going down. So this is very strange to understand why that is.
That's because in After Effects, 0,0 is in the uper left hand corner of the comp. To move toward the bottom of the comp, the change in Y is positive. To move toward the top of the comp, the change in Y is NEGATIVE.
It has ALWAYS been this way; I'm confused why you think it has changed..

Where it is? In what EXCATLY place is it? Can you show me? Without these I can't understand. Where is that place? Idon't know what are you talking about.
If you think good, it shouldn't be in that way.
Oh, for Heaven's sake.
Here's an example in a 1280x720 comp: the pixel in the uppermost left portion of the comp is 0,0. The pixel in lowermost right portion of the comp is 1280,720. The center of the comp is 640, 360.
If you have trouble grasping this oh-so radical, 21-year-old concept, I STRONGLY recommend spending a LOT of time visiting the pages you will find here:
