You can either File/Export Video to make an MOV file that Premiere can import, or you could do a publish to SWF, and import that into Premiere. What way of exporting are you trying at the moment? What items are in the timeline?
I tried to export the video into an MOV file and also in a SWF file , but when i try to open it, the player says that the file is not supported or there isn't any audio/video stream aviable.
In the timeline there are some motion tweens and some keyframes.
If you're on Windows, do you have QuickTime installed? Are you able to post a file somewhere, so I can try exporting to Premiere with your file?
Thank to you i solved the problem: there wasn't QuickTime installated on my computer and i couldn't open it or post it anywhere. Now i've installated it and the problem is solved.
