Position changes after last keyframe randomly

Hi,

Since the last update, I'm having problems with After Effects. When I place a position keyframe, I go a frame forward and my layers move to a different position, as if there was another keyframe, but there is none, it's the last one. Nothing to do with keyframe interpolation. Anyone knows what happens?

Thanks in advance

I think that the problem is that I have an adjustment layer on top of everything with a posterize time effect with a frame rate of 12 fps (my comp is 25fps). I have muted that layer and now it works. Then I have unmuted it and the final (and correct) position of the layers is one frame after the last position keyframe (where no keyframes are). Dont know if my explanation is a mess, sorry. 


That's it! It gets a little weird to think about, but you have to remember that Posterize Time means you won't always be seeing the effect of your keyframes when they happen - it may be a couple frames later, depending on the settings.

Without any system info and screenshots nobody can tell you much. the only thing that immediately comes to mind are potential issues with corrupted caches or somehow a "bad" mouse registration making you move stuff inadvertently. Outside that the usual stuff applies: Check your hardware acceleration settings, turn off multiframe and speculative rendering, update your graphics driver, flush the caches and experiment with the display settings.

The cache is cleared, graphics driver are updated and have turned off multiframe but still the same. It's been happening only in the last project, I assume that has smt to do with an update because it's something that has never happened to me before.

There's enough going on here that isn't visible that it will be very hard for us to diagnose. I would start by confirming that you don't have any parent or camera layers that are actually causing what you're seeing. 

It doesn't appear that you're seeing any of the unintended auto-bezier "boomerang" behavior on your motion paths, but eliminating that as a variable would also be a good thing to confirm. 

 

If you're only seeing this behavior in the above project, your issue is almost certainly in the way you've built this project, and not a sudden change in AE's behavior.
