I'm using V3.04 of VideoPad with a Windows 8 computer. When I try to change a video clip to slow motion, it momentarily works, but on playback, the screen for that clip is black. The slowed down audio still plays, but there's no video showing on the clip.
If I undo the change, the video returns. This only happens when changing to go slower, not faster. It also happens in both Timeline and Storyboard modes.
