Could you please describe this a little more clearly? What do you mean by your keyframes jumping back or forth? Do you mean when you leave a composition and come back, they've moved? Or do you mean that they stick with the mouse movement even when you've let go? Or do you mean something else?
Yes is definitely feels like they move when I let go of the mouse... pretty much anything on the timeline that is selected moves a few frames back or forward as if it gets stuck before you let go of the mouse click.
Anyway is probably just me, already tried a different mouse but again I never noticed it before.
nvidia quatro k4000
Two monitors connected.
I've seen similar issues mentioned before, but it's pretty rare. Can you be as specific as possible about your system's setup, hardware, software, etc.? Are you using a Wacom tablet or similar? What sort of other devices are plugged into your machine? Try using CC 2014 for a bit. Does the problem occur there?
Dell u3011 monitor
Generic Pnp Monitor,
z620 workstation 32gb
Two monitors connected and from time to time I disconnect one and then connect a cintiq wacom screen,.. everything else just a standard set up. I use a couple of plug ins from Mt mograph and duik. (not sure if that will affect) AE
I did work with 2014cc and it was pretty smooth didn't notice anything similar before.
Again this bug is not repetitive it feels like when you let go of mouse the ram preview is holding info for less than a second. It is more noticeable when you align keyframes and they don't drop at the spot you want them to.
Thanks for reading though.
Could you unplug your Cintiq and try using a regular mouse for a while with AE and see if the problem remains?
I have had this same problem since CC 2015. Never had this happen in any other version of AE or any other application. I have posted about it here.
Here are my system specs:
Premiere Pro CC 2015
Win 7 64bit (up to date)
NVIDIA 970GTX (driver up to date)
2 x 4TB internal
12TB RAID 5 via USB 3.0
USB 2.0 and 3.0 drives
FireWire audio device (M-AUDIO FireWire1814)... although, I am not using it for playback. It is connected.
Footage is H.264, AI Files, JPG Stills, solids, and no third party plugs.
Cintiq hasn't been connected ever since the update and I usually do the whole -reconnect-reboot computer routine often when I notice something is wrong. Anyway, my coworker has the "exact" machine set up than myself and he have not done the upgrade...so once he get the 2015 cc update it we will find out. (but now he doesnt want to do it) lol
Well, he can feel free to upgrade, but make sure he checks the option to keep his old versions: keeping previous versions installed when installing CC 2015 applications | After Effects region of interest
That way, if CC 2015 doesn't work well for him, he can just use CC 2014
