Premiere does not export

i suggest to try, export, add to queue and export using AME.

you might try smart rendering.

You can render sections by marking an in and out (and use the render in to out option in the sequence menu) til you isolate the problem.

Odd that Kevin didn't suggest it as he wrote the post...

Hey Wolf,

Sorry! It's just hanging there on the blue progress bar? Weird. Usually, an error compiling movie dialog box is triggered. Perhaps there is an odd file in the Timeline. A large photo perhaps? Take a closer look for anything odd in the first third of the Timeline. I wish you luck in locating this "bad actor" and ridding your Timeline of that thing. Your export should be normal afterward. I hope!

Thanks,
Kevin
