Change Duration of clip
I am having trouble changing the duration of a clip. I can change the clip duration manually by selecting the clip and dragging it to the right to extend the time say from 10 seconds to 20 seconds, or down to 4 seconds. However, my problem is using the ^D shortcut or "Change Duration" via Modify tag. When I select the clip in the timeline, ^D, then change the time of the clip say from 10 seconds to 4 seconds (using counter in blue in the viewer section), then press return on my keyboard: my playhead moves to 4 seconds instead of the duration changing to 4 seconds. I have troubleshooted with many different scenarios and clips, reset preferences, but nothing seems to help. Please, if anyone knows the fix to this, I would be very happy to hear from you ...
