Are you sure it doesn't mean "Internal test error"? Is there any numeric error code? If it occurs again, maybe you can give us that info along with some system specs and what exactly is involved in your project/ comp settings/ render settings, what footage you use, what effects and so on.
Hello Mylenium, sure i´ve ment "internal test error".
I get no special error code just this message.
I had a picture in jpg-format (621kb), two hour audio mp3-file(270MB), After Effects Audioline Effect and nothing more.
This error appears since the newest version of After Effect appeared.
Have you consdidered substituting the MP3 file with a WAV/ AIFF version converted in an audio program? AE has become better at dealing with such stuff, but the file may still have some oddities or damaged (audio) frames that throw AE for a loop, especially with so long a piece. It may simply cause something odd with the media cache. Perhaps you can try that first.
The audiofile was recorded as a mp3 and was not converted.
Maybe i should look for the media cache, i hope this helps.
Thank you so far Mylenium :-)
