I open an old PSD file that I used to create and animated gif with. The timline panel showed the animation frames and I was able to preview it with its play button. I then used the Timeline Fly-out menu and clicked convert to Video Timeline. The frames became a single layer and the Timeline panel showed a single video clip which I previewed using the play button in the Timeline Panel. I then used the timeline fly-out menu and clicked render video. After some time a pop-up window with a progress bar appeared with the title initialization video export its progress bar went to 3/4 the length and hung there in a loop. Using the pop-up window's cancel button closed the initialization video export window however soon a new initialization video export pop-up showed up the progress bar when to 3/4 and hung looping. Tried several timed to cancel would up having to terminate CS6 with the task manager.
