Attempt to get a value from a time stream with no key values ( 29 :: 36 )

everytime I try to put in a preset on this one clip it says after efects error: attempt to get a value from a time stream with no key values

我最近遇到同样问题，而且无法另存文件，简单操作后软件就会崩溃。排查后是Form插件的问题，我把Form插件删除后，工程可以另存了。

i need help because when i open ae and open the video file it automatticaly crashes and i cant even open it 

Hello everybody.

The way I resolved this issue, was by deleting layer by layer until I found the problematic one, and re-did it.

The issue occured on my 3rd party plugin from Red Giant Universe on a text layer.

Unfortunately opening the older project and removing the plugins and keyframes didn't work. Any other ideas?

Thanks @Mylenium for good questions. Here's some more info -

The project was originally created in version 13.5.1 (mac 64) and now is being opened and converted to work with the latest version of After Effects.

There are a few dozen comps in the file. Sadly some of the footage associate with the file was lost due to a hard drive failure a few years ago. I have replaced the files sans a few and that issue seems to be working its way out. The downside is that because AE won't let me successfully save the file after converting it (when it does save it's a blank file with no comps) due to the error. This means when I open the file and replace and repair the missing content that work is for not and isn't able to be saved.

Also strangely enough the comps don't seem to update or show anything in the comp preview panel. Meaning, when I change aspects of the comps I don't see any changes in the window displayed.

It also lists three plugins as missing - DE ElectricArcs, DE Glower and DE Sparks which are all  DigieEffects plugins. However, I have the plugins still in my system the issue is that at some point DigieEffects updated the plugins to be named without the DE. It also seems that they removed the Glower plugin.

Maybe the issue is I need to track down the plugins that are missing and try them out? I have already contacted DigieEffects tech support and have heard nothing.

Here is the troubled file in question in case anyone is curious - https://dl.dropboxusercontent.com/u/433483/AFD%20GO%20-%20ClassRoom.aep

It's a very odd situation!

Nobody can tell you anything without exact system info or other technical details like exact versions of AE - the one you are using now and the one the project was created with just as well as specific info about comp settings, effects and features used and so on. Just saying that it doesn't work is of no use to anyone.
