Huh ... just did a bunch of work yesterday/today with matching, without issue. Wonder what's up on your system ... or why it's behaving badly? Don't have a clue, so I'm hoping someone else will pop in with some ideas.
Yeah I wanna know what's up with it too lol. I have a ton of Premiere problems in general. My machine is a monster though, so it shouldn't have problems in theory (obviously anything can have problems). I've never had this problem before. I also have problems when I playback it pops. And premiere randomly completely freezes up a few times a day too.
