Hi,
I have this same problem. Just out of the bloom the multiclip stopped working on the viewer.
I have only been syncing my material and making multiclips.
I did do one sequence on the timeline and rendered it. But it does not explain why I can’t watch any of my multiclips simultaneously in viewer..
All the settings should be right. I also trashed all pref files.
Help.. this makes using multiclips a nightmare.
One funny thing though. If I make the viewer window smaller, like 120% the I can see the multiclips. They don’y look right, their slow.
Can anyone help me?
