After Effects warning: Undo group mismatch, will attempt to fix. Have reinstalled After Effects a number of times, and now have a new computer. IT support at work are baffled. This happens as a result of not being able to import files in the normal way (File> Import, double click the media browser, right click on media browser and import) This is not a continuous issue, when I first open AE, I am able to work as normal, import at normal. Only after importing a few different comps does this begin to happen. I am suddenly unable to import any type of file or media. It does not respond or react to opening a box to even begin browsing for what I wish to import. The only other way to import would be to drag and drop my desired media into the project. As a result, when attempting to edit key frames for that imported item, this error (as before) will appear, and all imported media will disappear. Any idea how on earth to fix this issue, or what else I can do? The work around I have at the moment, is to close AE and reopen it, for it to work for about 30 mins before stopping again. it also quite often crashes when this pop up appears.

Anything from cache corruption to leaky plug-ins used in the projects to CoDec issues. Impossible to tell, since you have not provided any exact info.

AE CC, Version: 13.2.0.49 As far as concerned, this is completely up to date.

Mac OSX Yosemite version 10.10.2

please see attached screen shots for the error messages in full.

exact sequence varies  for this issue to happen. import failure through typical steps (file>import, double click, right click) will only import via drag and drop.

when dragging and dropping media to the project, and is adjusted (scale, position, key frames) the error message(s) will come up, and the dragged and dropped media disappears, all changes are undone.

Never used to have a problem before we updated to the cloud. not just me that is affected, another colleague is too.

no thid party hardware.

source footage varies from jpegs, to png's.

quicktime version 10.4

also running adobe premiere pro with no known issues.

no third party effects installed

do not know if using Open GL, I cannot see it in preferences, preview where it normally is.

no problems with output, issues with work flow.

specs of my machine are attached in screen shot. I have recently changed computers, the issue has been present on both. Screen Shot 2015-02-03 at 15.05.13.png

Hi Katie,

Although the After Effects team has heard about this problem from some users, we haven't been able to reproduce this behavior. This usually means there is a condition or behavior related to the issue that we're not aware of. I'd like to ask for your help with exposing what we're missing.

Here is another thread where I've asked for additional data from other users:

https://forums.adobe.com/message/7145447#7145447

Summarizing, what I'd like to get from you is:

1. A process sample (via Activity Monitor) immediately after you encounter the problem.

2. An After Effects Log file (see Help > Enable Loggins and Reveal Logging File) taken immediately after you encounter the problem.

3. A system report from your computer (Apple menu > About this Mac, click System Report, save this file).

Additional information you can offer about your machine, including Finder extensions, pointing devices installed, or anything else you can think of could be useful.

Please send this data to me. My email address is myLastName at Adobe dot com.

Thanks!

This is seriously one of the most annoying aspects about AE CC2015. Any time i use command x to cut a layer out of a composition, immediate error window that repeats 3 times until it goes away. Any time i remove a keyframe, error 3 times.

El Capitan,

AE CC2015 13.5.0.347

Nothing in my timeline besides cameras, nulls and solids.

Is there a reason you're not on the latest version? 13.5.1. fixed quite a few bugs (and introduced one or two others, but...)

Ah interesting. Although I know for a fact it has not fixed this because I am bouncing back and forth between desktop and laptop and my desktop is completely up to date. Seems to be happening on both computers.

Since you are quick and awesome with responses, do you know a way to revert back to the timeline controls of 2014? Mostly in regards to pressing spacebar to play, and then spacebar again to pause. Currently it seems like hitting spacebar again to pause doesnt work and it takes 2 or 3 presses to get the scrubber to stop playing. Is there any way to only preview with the numpad and not spacebar? "the shortcut" pulldown menu does not seem to fix this when setting to numpad

That's pretty annoying, isn't it? I'll try to explain what it's doing so it might make more sense. Pressing spacebar starts a preview. That's fine and dandy. However, if the timeline isn't fully cached when you press spacebar again, it just starts real-time previewing what has been cached. Thus, you often have to press it multiple times before it stops.

Like I said, annoying.

That'll be fixed in next months big update. With all the bugs being fixed and this change to the previews, next month's update could make CC 2015 useable for most folks who aren't using it in production yet. We'll have to wait and see.

Here's more info on next month's update: What’s new and changed in the upcoming update to After Effects CC 2015

I think so. It depends on what you're asking - I'm not quite sure what you meant. Here's a page on how Previewing currently works: all about previews in After Effects CC 2015 (13.5) |

That explains it in far more detail than I could and it might help alleviate some of your issues until the update comes out next month.

Typically this can happen in any comp. I do not use any plug-in's. I use solids and masks to make simple animated charts, statistics and name straps. This error appears when altering key frames after importing an image. I have added a screen shot of a typical project. I hope this helps.
