Purchased recently, but I'm having a problem. Suppose I go to "Open Video", ok? Now, when I have that small window and I'm about ot choose from a group of videos, I click one of them once, then click the "Duration" button in the small window. That's so I could specify a certain length instead of inserting the whole video as frames. Problem is, it works with some videos, but not all. When it works, I can choose the duration. But the problem is when I click it and it doesn't show the whole video, just the first 4 seconds or so (all black).
Is there a solution? Thanks.
