This is the Aero forum. I can’t move your post; please repost the the Premier forum:

I don’t use Premiere, but I found this on a help page under the subheading “Performance, playback, and stability”:

”A 12000 error message could appear when software rendering fallback occurred in the timeline while using Film Impact plugins.”

If you are or are not using the Film Impact plugin, be sure to mention that when you repost.
