Have I discovered a bug or is this a known issue?
I created an audio clip (SFX1) of 470ms duration. When I try to export to After Effects CTA4 crashes.
So I used Adobe Audition to add silence to the end of the audio, making the duration 1.5s. The project exported to Ae just fine.
From an earlier project I had SFX of 1.1s and that exported no problem.
So it appears CTA4 crashes with audio of less than 1s duration. Can someone confirm this, or correct me in some way?

As an aside, CAT4 does not respect the imported audio format. When CTA4 exports to After Effects, it converts all audio to WAV format. This is a pain if you have gone to the trouble of preparing mp3 before importing into CTA4. There should be a preference to say whether or not audio in the project will be converted.
