Trash preferences and repair permissions . See if that helps.
I would check to be sure your work area bar is
not shorter than your sequence length.
Double-click the work area bar to resize it to either the width
of the time ruler, or the length of the entire sequence, whichever is shorter.
To define the whole sequence as the work area, the whole sequence
must be visible in the Timeline panel.
Hi all, thanks for the help.
Work bar area is all good, everything else looks fine.
We tried trashing the preferences too.
Now, turns out that this seems to be a problem with the media encoder perhaps as it only happens when we queue export not when we export directly.
Along the same lines of the WAB (Work Area Bar), one can set an In and an Out Point for the Timeline. This can happen by accident in that if one hits the O key, with the Playhead/CTI short of the end, they can add an Out Point to the Timeline. If there are In Points, or Out Points, the density of the area around the Timeline Ruler will change, so it stands out, but not by THAT much. Check for a Timeline Out Point.
As with the WAB, there can be instances where the setting does not affect an Export, and it could be that with direct Export it does not come into play (pure speculation on my part here).
Just thinking on what could limit your Export.
Whenever I have this "problem" I apply any kind of video filter at that area, but leave the settings so it really doesn't change anything (like maybe a broadcast filter or a brightness/contrast left at 0. Then render it. Then reexport. This has never failed to get me over those mystery bad export areas.
Worth a shot.
