When trying to export a sequence thorugh "Edit in Adobe Audtition" (with video preview), Premiere never gets passed the "Preparing Sequence Data" which runs infinitely.
When selecting the preview video option it actually makes it through the "Preparing Video for Adobe Audition..." and then runs the "Preparing Audio for Adobe Audition" process fine but then craps out on the next step and never makes it into Audition.
It is only a 13 minute clip that I am attempting to bring into Audition and when not selecting video preview, which i need to sync up the audio edits, it seems to work the majority of the time.
I'm late to the game here, but I just had the same problem. Once I removed the video feed from the dynamic link, I no longer had this problem.
