Cubase Pro 11.0.30 Windows.
- Import 2 hour video (mp4)
- Set project start time to more than 1 hour (e.g., 01:20:00:00)
- Press F8 to show video window
- Video window will be black yet thumbnails can be seen on timeline and audio from video will be played
– on step 2 make it less than one hour, and it works correctly. One frame over 1 hour triggers the bug.
