Thanks Andrew, this is the most frustrating problem I have ever encountered in this software. Collapsing the multiclips didn’t seem to help. There are portions of the timeline that playback correctly, meaning that you see all the angles in the viewer and they are synced, these have a green code in the render bar, however when the timeline reaches a gray code the viewer has the same image that is in the canvas. If I import a new clip into the timeline it works perfectly, only the previously edited mutliclips seem to have a problem which makes me think I accidently did something. I have multiclip playback checked on and also the sync open in the viewer.
