Possible Cause:

1. The clip begins with black frames.

2. At some hardware configurations, the CUE function does not always work properly. It is machine-dependent.

Solution:

1. Make sure that the clip’s first frame is not black. Edit the clip with Clip Trimmer to trim the black frames from the clip beginning.

2. Go to Settings > General dialog box > Cue Delay.

This option defines a small delay before pausing on the first frame. Please, try to find the best one for your case.
